Guzzle Upgrade Guide
|
||
|
====================
|
||
|
|
||
|
5.0 to 6.0
|
||
|
----------
|
||
|
|
||
|
Guzzle now uses [PSR-7](http://www.php-fig.org/psr/psr-7/) for HTTP messages.
|
||
|
Due to the fact that these messages are immutable, this prompted a refactoring
|
||
|
of Guzzle to use a middleware based system rather than an event system. Any
|
||
|
HTTP message interaction (e.g., `GuzzleHttp\Message\Request`) need to be
|
||
|
updated to work with the new immutable PSR-7 request and response objects. Any
|
||
|
event listeners or subscribers need to be updated to become middleware
|
||
|
functions that wrap handlers (or are injected into a
|
||
|
`GuzzleHttp\HandlerStack`).
|
||
|
|
||
|
- Removed `GuzzleHttp\BatchResults`
|
||
|
- Removed `GuzzleHttp\Collection`
|
||
|
- Removed `GuzzleHttp\HasDataTrait`
|
||
|
- Removed `GuzzleHttp\ToArrayInterface`
|
||
|
- The `guzzlehttp/streams` dependency has been removed. Stream functionality
|
||
|
is now present in the `GuzzleHttp\Psr7` namespace provided by the
|
||
|
`guzzlehttp/psr7` package.
|
||
|
- Guzzle no longer uses ReactPHP promises and now uses the
|
||
|
`guzzlehttp/promises` library. We use a custom promise library for three
|
||
|
significant reasons:
|
||
|
1. React promises (at the time of writing this) are recursive. Promise
|
||
|
chaining and promise resolution will eventually blow the stack. Guzzle
|
||
|
promises are not recursive as they use a sort of trampolining technique.
|
||
|
Note: there has been movement in the React project to modify promises to
|
||
|
no longer utilize recursion.
|
||
|
2. Guzzle needs to have the ability to synchronously block on a promise to
|
||
|
wait for a result. Guzzle promises allows this functionality (and does
|
||
|
not require the use of recursion).
|
||
|
3. Because we need to be able to wait on a result, doing so using React
|
||
|
promises requires wrapping react promises with RingPHP futures. This
|
||
|
overhead is no longer needed, reducing stack sizes, reducing complexity,
|
||
|
and improving performance.
|
||
|
- `GuzzleHttp\Mimetypes` has been moved to a function in
|
||
|
`GuzzleHttp\Psr7\mimetype_from_extension` and
|
||
|
`GuzzleHttp\Psr7\mimetype_from_filename`.
|
||
|
- `GuzzleHttp\Query` and `GuzzleHttp\QueryParser` have been removed. Query
|
||
|
strings must now be passed into request objects as strings, or provided to
|
||
|
the `query` request option when creating requests with clients. The `query`
|
||
|
option uses PHP's `http_build_query` to convert an array to a string. If you
|
||
|
need a different serialization technique, you will need to pass the query
|
||
|
string in as a string. There are a couple helper functions that will make
|
||
|
working with query strings easier: `GuzzleHttp\Psr7\parse_query` and
|
||
|
`GuzzleHttp\Psr7\build_query`.
|
||
|
- Guzzle no longer has a dependency on RingPHP. Due to the use of a middleware
|
||
|
system based on PSR-7, using RingPHP and it's middleware system as well adds
|
||
|
more complexity than the benefits it provides. All HTTP handlers that were
|
||
|
present in RingPHP have been modified to work directly with PSR-7 messages
|
||
|
and placed in the `GuzzleHttp\Handler` namespace. This significantly reduces
|
||
|
complexity in Guzzle, removes a dependency, and improves performance. RingPHP
|
||
|
will be maintained for Guzzle 5 support, but will no longer be a part of
|
||
|
Guzzle 6.
|
||
|
- As Guzzle now uses a middleware based systems the event system and RingPHP
|
||
|
integration has been removed. Note: while the event system has been removed,
|
||
|
it is possible to add your own type of event system that is powered by the
|
||
|
middleware system.
|
||
|
- Removed the `Event` namespace.
|
||
|
- Removed the `Subscriber` namespace.
|
||
|
- Removed `Transaction` class
|
||
|
- Removed `RequestFsm`
|
||
|
- Removed `RingBridge`
|
||
|
- `GuzzleHttp\Subscriber\Cookie` is now provided by
|
||
|
`GuzzleHttp\Middleware::cookies`
|
||
|
- `GuzzleHttp\Subscriber\HttpError` is now provided by
|
||
|
`GuzzleHttp\Middleware::httpError`
|
||
|
- `GuzzleHttp\Subscriber\History` is now provided by
|
||
|
`GuzzleHttp\Middleware::history`
|
||
|
- `GuzzleHttp\Subscriber\Mock` is now provided by
|
||
|
`GuzzleHttp\Handler\MockHandler`
|
||
|
- `GuzzleHttp\Subscriber\Prepare` is now provided by
|
||
|
`GuzzleHttp\PrepareBodyMiddleware`
|
||
|
- `GuzzleHttp\Subscriber\Redirect` is now provided by
|
||
|
`GuzzleHttp\RedirectMiddleware`
|
||
|
- Guzzle now uses `Psr\Http\Message\UriInterface` (implements in
|
||
|
`GuzzleHttp\Psr7\Uri`) for URI support. `GuzzleHttp\Url` is now gone.
|
||
|
- Static functions in `GuzzleHttp\Utils` have been moved to namespaced
|
||
|
functions under the `GuzzleHttp` namespace. This requires either a Composer
|
||
|
based autoloader or you to include functions.php.
|
||
|
- `GuzzleHttp\ClientInterface::getDefaultOption` has been renamed to
|
||
|
`GuzzleHttp\ClientInterface::getConfig`.
|
||
|
- `GuzzleHttp\ClientInterface::setDefaultOption` has been removed.
|
||
|
- The `json` and `xml` methods of response objects has been removed. With the
|
||
|
migration to strictly adhering to PSR-7 as the interface for Guzzle messages,
|
||
|
adding methods to message interfaces would actually require Guzzle messages
|
||
|
to extend from PSR-7 messages rather then work with them directly.
|
||
|
|
||
|
## Migrating to middleware
|
||
|
|
||
|
The change to PSR-7 unfortunately required significant refactoring to Guzzle
|
||
|
due to the fact that PSR-7 messages are immutable. Guzzle 5 relied on an event
|
||
|
system from plugins. The event system relied on mutability of HTTP messages and
|
||
|
side effects in order to work. With immutable messages, you have to change your
|
||
|
workflow to become more about either returning a value (e.g., functional
|
||
|
middlewares) or setting a value on an object. Guzzle v6 has chosen the
|
||
|
functional middleware approach.
|
||
|
|
||
|
Instead of using the event system to listen for things like the `before` event,
|
||
|
you now create a stack based middleware function that intercepts a request on
|
||
|
the way in and the promise of the response on the way out. This is a much
|
||
|
simpler and more predictable approach than the event system and works nicely
|
||
|
with PSR-7 middleware. Due to the use of promises, the middleware system is
|
||
|
also asynchronous.
|
||
|
|
||
|
v5:
|
||
|
|
||
|
```php
|
||
|
use GuzzleHttp\Event\BeforeEvent;
|
||
|
$client = new GuzzleHttp\Client();
|
||
|
// Get the emitter and listen to the before event.
|
||
|
$client->getEmitter()->on('before', function (BeforeEvent $e) {
|
||
|
// Guzzle v5 events relied on mutation
|
||
|
$e->getRequest()->setHeader('X-Foo', 'Bar');
|
||
|
});
|
||
|
```
|
||
|
|
||
|
v6:
|
||
|
|
||
|
In v6, you can modify the request before it is sent using the `mapRequest`
|
||
|
middleware. The idiomatic way in v6 to modify the request/response lifecycle is
|
||
|
to setup a handler middleware stack up front and inject the handler into a
|
||
|
client.
|
||
|
|
||
|
```php
|
||
|
use GuzzleHttp\Middleware;
|
||
|
// Create a handler stack that has all of the default middlewares attached
|
||
|
$handler = GuzzleHttp\HandlerStack::create();
|
||
|
// Push the handler onto the handler stack
|
||
|
$handler->push(Middleware::mapRequest(function (RequestInterface $request) {
|
||
|
// Notice that we have to return a request object
|
||
|
return $request->withHeader('X-Foo', 'Bar');
|
||
|
}));
|
||
|
// Inject the handler into the client
|
||
|
$client = new GuzzleHttp\Client(['handler' => $handler]);
|
||
|
```
|
||
|
|
||
|
## POST Requests
|
||
|
|
||
|
This version added the [`form_params`](http://guzzle.readthedocs.org/en/latest/request-options.html#form_params)
|
||
|
and `multipart` request options. `form_params` is an associative array of
|
||
|
strings or array of strings and is used to serialize an
|
||
|
`application/x-www-form-urlencoded` POST request. The
|
||
|
[`multipart`](http://guzzle.readthedocs.org/en/latest/request-options.html#multipart)
|
||
|
option is now used to send a multipart/form-data POST request.
|
||
|
|
||
|
`GuzzleHttp\Post\PostFile` has been removed. Use the `multipart` option to add
|
||
|
POST files to a multipart/form-data request.
|
||
|
|
||
|
The `body` option no longer accepts an array to send POST requests. Please use
|
||
|
`multipart` or `form_params` instead.
|
||
|
|
||
|
The `base_url` option has been renamed to `base_uri`.
|
||
|
|
||
|
4.x to 5.0
|
||
|
----------
|
||
|
|
||
|
## Rewritten Adapter Layer
|
||
|
|
||
|
Guzzle now uses [RingPHP](http://ringphp.readthedocs.org/en/latest) to send
|
||
|
HTTP requests. The `adapter` option in a `GuzzleHttp\Client` constructor
|
||
|
is still supported, but it has now been renamed to `handler`. Instead of
|
||
|
passing a `GuzzleHttp\Adapter\AdapterInterface`, you must now pass a PHP
|
||
|
`callable` that follows the RingPHP specification.
|
||
|
|
||
|
## Removed Fluent Interfaces
|
||
|
|
||
|
[Fluent interfaces were removed](http://ocramius.github.io/blog/fluent-interfaces-are-evil)
|
||
|
from the following classes:
|
||
|
|
||
|
- `GuzzleHttp\Collection`
|
||
|
- `GuzzleHttp\Url`
|
||
|
- `GuzzleHttp\Query`
|
||
|
- `GuzzleHttp\Post\PostBody`
|
||
|
- `GuzzleHttp\Cookie\SetCookie`
|
||
|
|
||
|
## Removed functions.php
|
||
|
|
||
|
Removed "functions.php", so that Guzzle is truly PSR-4 compliant. The following
|
||
|
functions can be used as replacements.
|
||
|
|
||
|
- `GuzzleHttp\json_decode` -> `GuzzleHttp\Utils::jsonDecode`
|
||
|
- `GuzzleHttp\get_path` -> `GuzzleHttp\Utils::getPath`
|
||
|
- `GuzzleHttp\Utils::setPath` -> `GuzzleHttp\set_path`
|
||
|
- `GuzzleHttp\Pool::batch` -> `GuzzleHttp\batch`. This function is, however,
|
||
|
deprecated in favor of using `GuzzleHttp\Pool::batch()`.
|
||
|
|
||
|
The "procedural" global client has been removed with no replacement (e.g.,
|
||
|
`GuzzleHttp\get()`, `GuzzleHttp\post()`, etc.). Use a `GuzzleHttp\Client`
|
||
|
object as a replacement.
|
||
|
|
||
|
## `throwImmediately` has been removed
|
||
|
|
||
|
The concept of "throwImmediately" has been removed from exceptions and error
|
||
|
events. This control mechanism was used to stop a transfer of concurrent
|
||
|
requests from completing. This can now be handled by throwing the exception or
|
||
|
by cancelling a pool of requests or each outstanding future request
|
||
|
individually.
|
||
|
|
||
|
## headers event has been removed
|
||
|
|
||
|
Removed the "headers" event. This event was only useful for changing the
|
||
|
body a response once the headers of the response were known. You can implement
|
||
|
a similar behavior in a number of ways. One example might be to use a
|
||
|
FnStream that has access to the transaction being sent. For example, when the
|
||
|
first byte is written, you could check if the response headers match your
|
||
|
expectations, and if so, change the actual stream body that is being
|
||
|
written to.
|
||
|
|
||
|
## Updates to HTTP Messages
|
||
|
|
||
|
Removed the `asArray` parameter from
|
||
|
`GuzzleHttp\Message\MessageInterface::getHeader`. If you want to get a header
|
||
|
value as an array, then use the newly added `getHeaderAsArray()` method of
|
||
|
`MessageInterface`. This change makes the Guzzle interfaces compatible with
|
||
|
the PSR-7 interfaces.
|
||
|
|
||
|
3.x to 4.0
|
||
|
----------
|
||
|
|
||
|
## Overarching changes:
|
||
|
|
||
|
- Now requires PHP 5.4 or greater.
|
||
|
- No longer requires cURL to send requests.
|
||
|
- Guzzle no longer wraps every exception it throws. Only exceptions that are
|
||
|
recoverable are now wrapped by Guzzle.
|
||
|
- Various namespaces have been removed or renamed.
|
||
|
- No longer requiring the Symfony EventDispatcher. A custom event dispatcher
|
||
|
based on the Symfony EventDispatcher is
|
||
|
now utilized in `GuzzleHttp\Event\EmitterInterface` (resulting in significant
|
||
|
speed and functionality improvements).
|
||
|
|
||
|
Changes per Guzzle 3.x namespace are described below.
|
||
|
|
||
|
## Batch
|
||
|
|
||
|
The `Guzzle\Batch` namespace has been removed. This is best left to
|
||
|
third-parties to implement on top of Guzzle's core HTTP library.
|
||
|
|
||
|
## Cache
|
||
|
|
||
|
The `Guzzle\Cache` namespace has been removed. (Todo: No suitable replacement
|
||
|
has been implemented yet, but hoping to utilize a PSR cache interface).
|
||
|
|
||
|
## Common
|
||
|
|
||
|
- Removed all of the wrapped exceptions. It's better to use the standard PHP
|
||
|
library for unrecoverable exceptions.
|
||
|
- `FromConfigInterface` has been removed.
|
||
|
- `Guzzle\Common\Version` has been removed. The VERSION constant can be found
|
||
|
at `GuzzleHttp\ClientInterface::VERSION`.
|
||
|
|
||
|
### Collection
|
||
|
|
||
|
- `getAll` has been removed. Use `toArray` to convert a collection to an array.
|
||
|
- `inject` has been removed.
|
||
|
- `keySearch` has been removed.
|
||
|
- `getPath` no longer supports wildcard expressions. Use something better like
|
||
|
JMESPath for this.
|
||
|
- `setPath` now supports appending to an existing array via the `[]` notation.
|
||
|
|
||
|
### Events
|
||
|
|
||
|
Guzzle no longer requires Symfony's EventDispatcher component. Guzzle now uses
|
||
|
`GuzzleHttp\Event\Emitter`.
|
||
|
|
||
|
- `Symfony\Component\EventDispatcher\EventDispatcherInterface` is replaced by
|
||
|
`GuzzleHttp\Event\EmitterInterface`.
|
||
|
- `Symfony\Component\EventDispatcher\EventDispatcher` is replaced by
|
||
|
`GuzzleHttp\Event\Emitter`.
|
||
|
- `Symfony\Component\EventDispatcher\Event` is replaced by
|
||
|
`GuzzleHttp\Event\Event`, and Guzzle now has an EventInterface in
|
||
|
`GuzzleHttp\Event\EventInterface`.
|
||
|
- `AbstractHasDispatcher` has moved to a trait, `HasEmitterTrait`, and
|
||
|
`HasDispatcherInterface` has moved to `HasEmitterInterface`. Retrieving the
|
||
|
event emitter of a request, client, etc. now uses the `getEmitter` method
|
||
|
rather than the `getDispatcher` method.
|
||
|
|
||
|
#### Emitter
|
||
|
|
||
|
- Use the `once()` method to add a listener that automatically removes itself
|
||
|
the first time it is invoked.
|
||
|
- Use the `listeners()` method to retrieve a list of event listeners rather than
|
||
|
the `getListeners()` method.
|
||
|
- Use `emit()` instead of `dispatch()` to emit an event from an emitter.
|
||
|
- Use `attach()` instead of `addSubscriber()` and `detach()` instead of
|
||
|
`removeSubscriber()`.
|
||
|
|
||
|
```php
|
||
|
$mock = new Mock();
|
||
|
// 3.x
|
||
|
$request->getEventDispatcher()->addSubscriber($mock);
|
||
|
$request->getEventDispatcher()->removeSubscriber($mock);
|
||
|
// 4.x
|
||
|
$request->getEmitter()->attach($mock);
|
||
|
$request->getEmitter()->detach($mock);
|
||
|
```
|
||
|
|
||
|
Use the `on()` method to add a listener rather than the `addListener()` method.
|
||
|
|
||
|
```php
|
||
|
// 3.x
|
||
|
$request->getEventDispatcher()->addListener('foo', function (Event $event) { /* ... */ } );
|
||
|
// 4.x
|
||
|
$request->getEmitter()->on('foo', function (Event $event, $name) { /* ... */ } );
|
||
|
```
|
||
|
|
||
|
## Http
|
||
|
|
||
|
### General changes
|
||
|
|
||
|
- The cacert.pem certificate has been moved to `src/cacert.pem`.
|
||
|
- Added the concept of adapters that are used to transfer requests over the
|
||
|
wire.
|
||
|
- Simplified the event system.
|
||
|
- Sending requests in parallel is still possible, but batching is no longer a
|
||
|
concept of the HTTP layer. Instead, you must use the `complete` and `error`
|
||
|
events to asynchronously manage parallel request transfers.
|
||
|
- `Guzzle\Http\Url` has moved to `GuzzleHttp\Url`.
|
||
|
- `Guzzle\Http\QueryString` has moved to `GuzzleHttp\Query`.
|
||
|
- QueryAggregators have been rewritten so that they are simply callable
|
||
|
functions.
|
||
|
- `GuzzleHttp\StaticClient` has been removed. Use the functions provided in
|
||
|
`functions.php` for an easy to use static client instance.
|
||
|
- Exceptions in `GuzzleHttp\Exception` have been updated to all extend from
|
||
|
`GuzzleHttp\Exception\TransferException`.
|
||
|
|
||
|
### Client
|
||
|
|
||
|
Calling methods like `get()`, `post()`, `head()`, etc. no longer create and
|
||
|
return a request, but rather creates a request, sends the request, and returns
|
||
|
the response.
|
||
|
|
||
|
```php
|
||
|
// 3.0
|
||
|
$request = $client->get('/');
|
||
|
$response = $request->send();
|
||
|
|
||
|
// 4.0
|
||
|
$response = $client->get('/');
|
||
|
|
||
|
// or, to mirror the previous behavior
|
||
|
$request = $client->createRequest('GET', '/');
|
||
|
$response = $client->send($request);
|
||
|
```
|
||
|
|
||
|
`GuzzleHttp\ClientInterface` has changed.
|
||
|
|
||
|
- The `send` method no longer accepts more than one request. Use `sendAll` to
|
||
|
send multiple requests in parallel.
|
||
|
- `setUserAgent()` has been removed. Use a default request option instead. You
|
||
|
could, for example, do something like:
|
||
|
`$client->setConfig('defaults/headers/User-Agent', 'Foo/Bar ' . $client::getDefaultUserAgent())`.
|
||
|
- `setSslVerification()` has been removed. Use default request options instead,
|
||
|
like `$client->setConfig('defaults/verify', true)`.
|
||
|
|
||
|
`GuzzleHttp\Client` has changed.
|
||
|
|
||
|
- The constructor now accepts only an associative array. You can include a
|
||
|
`base_url` string or array to use a URI template as the base URL of a client.
|
||
|
You can also specify a `defaults` key that is an associative array of default
|
||
|
request options. You can pass an `adapter` to use a custom adapter,
|
||
|
`batch_adapter` to use a custom adapter for sending requests in parallel, or
|
||
|
a `message_factory` to change the factory used to create HTTP requests and
|
||
|
responses.
|
||
|
- The client no longer emits a `client.create_request` event.
|
||
|
- Creating requests with a client no longer automatically utilize a URI
|
||
|
template. You must pass an array into a creational method (e.g.,
|
||
|
`createRequest`, `get`, `put`, etc.) in order to expand a URI template.
|
||
|
|
||
|
### Messages
|
||
|
|
||
|
Messages no longer have references to their counterparts (i.e., a request no
|
||
|
longer has a reference to it's response, and a response no loger has a
|
||
|
reference to its request). This association is now managed through a
|
||
|
`GuzzleHttp\Adapter\TransactionInterface` object. You can get references to
|
||
|
these transaction objects using request events that are emitted over the
|
||
|
lifecycle of a request.
|
||
|
|
||
|
#### Requests with a body
|
||
|
|
||
|
- `GuzzleHttp\Message\EntityEnclosingRequest` and
|
||
|
`GuzzleHttp\Message\EntityEnclosingRequestInterface` have been removed. The
|
||
|
separation between requests that contain a body and requests that do not
|
||
|
contain a body has been removed, and now `GuzzleHttp\Message\RequestInterface`
|
||
|
handles both use cases.
|
||
|
- Any method that previously accepts a `GuzzleHttp\Response` object now accept a
|
||
|
`GuzzleHttp\Message\ResponseInterface`.
|
||
|
- `GuzzleHttp\Message\RequestFactoryInterface` has been renamed to
|
||
|
`GuzzleHttp\Message\MessageFactoryInterface`. This interface is used to create
|
||
|
both requests and responses and is implemented in
|
||
|
`GuzzleHttp\Message\MessageFactory`.
|
||
|
- POST field and file methods have been removed from the request object. You
|
||
|
must now use the methods made available to `GuzzleHttp\Post\PostBodyInterface`
|
||
|
to control the format of a POST body. Requests that are created using a
|
||
|
standard `GuzzleHttp\Message\MessageFactoryInterface` will automatically use
|
||
|
a `GuzzleHttp\Post\PostBody` body if the body was passed as an array or if
|
||
|
the method is POST and no body is provided.
|
||
|
|
||
|
```php
|
||
|
$request = $client->createRequest('POST', '/');
|
||
|
$request->getBody()->setField('foo', 'bar');
|
||
|
$request->getBody()->addFile(new PostFile('file_key', fopen('/path/to/content', 'r')));
|
||
|
```
|
||
|
|
||
|
#### Headers
|
||
|
|
||
|
- `GuzzleHttp\Message\Header` has been removed. Header values are now simply
|
||
|
represented by an array of values or as a string. Header values are returned
|
||
|
as a string by default when retrieving a header value from a message. You can
|
||
|
pass an optional argument of `true` to retrieve a header value as an array
|
||
|
of strings instead of a single concatenated string.
|
||
|
- `GuzzleHttp\PostFile` and `GuzzleHttp\PostFileInterface` have been moved to
|
||
|
`GuzzleHttp\Post`. This interface has been simplified and now allows the
|
||
|
addition of arbitrary headers.
|
||
|
- Custom headers like `GuzzleHttp\Message\Header\Link` have been removed. Most
|
||
|
of the custom headers are now handled separately in specific
|
||
|
subscribers/plugins, and `GuzzleHttp\Message\HeaderValues::parseParams()` has
|
||
|
been updated to properly handle headers that contain parameters (like the
|
||
|
`Link` header).
|
||
|
|
||
|
#### Responses
|
||
|
|
||
|
- `GuzzleHttp\Message\Response::getInfo()` and
|
||
|
`GuzzleHttp\Message\Response::setInfo()` have been removed. Use the event
|
||
|
system to retrieve this type of information.
|
||
|
- `GuzzleHttp\Message\Response::getRawHeaders()` has been removed.
|
||
|
- `GuzzleHttp\Message\Response::getMessage()` has been removed.
|
||
|
- `GuzzleHttp\Message\Response::calculateAge()` and other cache specific
|
||
|
methods have moved to the CacheSubscriber.
|
||
|
- Header specific helper functions like `getContentMd5()` have been removed.
|
||
|
Just use `getHeader('Content-MD5')` instead.
|
||
|
- `GuzzleHttp\Message\Response::setRequest()` and
|
||
|
`GuzzleHttp\Message\Response::getRequest()` have been removed. Use the event
|
||
|
system to work with request and response objects as a transaction.
|
||
|
- `GuzzleHttp\Message\Response::getRedirectCount()` has been removed. Use the
|
||
|
Redirect subscriber instead.
|
||
|
- `GuzzleHttp\Message\Response::isSuccessful()` and other related methods have
|
||
|
been removed. Use `getStatusCode()` instead.
|
||
|
|
||
|
#### Streaming responses
|
||
|
|
||
|
Streaming requests can now be created by a client directly, returning a
|
||
|
`GuzzleHttp\Message\ResponseInterface` object that contains a body stream
|
||
|
referencing an open PHP HTTP stream.
|
||
|
|
||
|
```php
|
||
|
// 3.0
|
||
|
use Guzzle\Stream\PhpStreamRequestFactory;
|
||
|
$request = $client->get('/');
|
||
|
$factory = new PhpStreamRequestFactory();
|
||
|
$stream = $factory->fromRequest($request);
|
||
|
$data = $stream->read(1024);
|
||
|
|
||
|
// 4.0
|
||
|
$response = $client->get('/', ['stream' => true]);
|
||
|
// Read some data off of the stream in the response body
|
||
|
$data = $response->getBody()->read(1024);
|
||
|
```
|
||
|
|
||
|
#### Redirects
|
||
|
|
||
|
The `configureRedirects()` method has been removed in favor of a
|
||
|
`allow_redirects` request option.
|
||
|
|
||
|
```php
|
||
|
// Standard redirects with a default of a max of 5 redirects
|
||
|
$request = $client->createRequest('GET', '/', ['allow_redirects' => true]);
|
||
|
|
||
|
// Strict redirects with a custom number of redirects
|
||
|
$request = $client->createRequest('GET', '/', [
|
||
|
'allow_redirects' => ['max' => 5, 'strict' => true]
|
||
|
]);
|
||
|
```
|
||
|
|
||
|
#### EntityBody
|
||
|
|
||
|
EntityBody interfaces and classes have been removed or moved to
|
||
|
`GuzzleHttp\Stream`. All classes and interfaces that once required
|
||
|
`GuzzleHttp\EntityBodyInterface` now require
|
||
|
`GuzzleHttp\Stream\StreamInterface`. Creating a new body for a request no
|
||
|
longer uses `GuzzleHttp\EntityBody::factory` but now uses
|
||
|
`GuzzleHttp\Stream\Stream::factory` or even better:
|
||
|
`GuzzleHttp\Stream\create()`.
|
||
|
|
||
|
- `Guzzle\Http\EntityBodyInterface` is now `GuzzleHttp\Stream\StreamInterface`
|
||
|
- `Guzzle\Http\EntityBody` is now `GuzzleHttp\Stream\Stream`
|
||
|
- `Guzzle\Http\CachingEntityBody` is now `GuzzleHttp\Stream\CachingStream`
|
||
|
- `Guzzle\Http\ReadLimitEntityBody` is now `GuzzleHttp\Stream\LimitStream`
|
||
|
- `Guzzle\Http\IoEmittyinEntityBody` has been removed.
|
||
|
|
||
|
#### Request lifecycle events
|
||
|
|
||
|
Requests previously submitted a large number of requests. The number of events
|
||
|
emitted over the lifecycle of a request has been significantly reduced to make
|
||
|
it easier to understand how to extend the behavior of a request. All events
|
||
|
emitted during the lifecycle of a request now emit a custom
|
||
|
`GuzzleHttp\Event\EventInterface` object that contains context providing
|
||
|
methods and a way in which to modify the transaction at that specific point in
|
||
|
time (e.g., intercept the request and set a response on the transaction).
|
||
|
|
||
|
- `request.before_send` has been renamed to `before` and now emits a
|
||
|
`GuzzleHttp\Event\BeforeEvent`
|
||
|
- `request.complete` has been renamed to `complete` and now emits a
|
||
|
`GuzzleHttp\Event\CompleteEvent`.
|
||
|
- `request.sent` has been removed. Use `complete`.
|
||
|
- `request.success` has been removed. Use `complete`.
|
||
|
- `error` is now an event that emits a `GuzzleHttp\Event\ErrorEvent`.
|
||
|
- `request.exception` has been removed. Use `error`.
|
||
|
- `request.receive.status_line` has been removed.
|
||
|
- `curl.callback.progress` has been removed. Use a custom `StreamInterface` to
|
||
|
maintain a status update.
|
||
|
- `curl.callback.write` has been removed. Use a custom `StreamInterface` to
|
||
|
intercept writes.
|
||
|
- `curl.callback.read` has been removed. Use a custom `StreamInterface` to
|
||
|
intercept reads.
|
||
|
|
||
|
`headers` is a new event that is emitted after the response headers of a
|
||
|
request have been received before the body of the response is downloaded. This
|
||
|
event emits a `GuzzleHttp\Event\HeadersEvent`.
|
||
|
|
||
|
You can intercept a request and inject a response using the `intercept()` event
|
||
|
of a `GuzzleHttp\Event\BeforeEvent`, `GuzzleHttp\Event\CompleteEvent`, and
|
||
|
`GuzzleHttp\Event\ErrorEvent` event.
|
||
|
|
||
|
See: http://docs.guzzlephp.org/en/latest/events.html
|
||
|
|
||
|
## Inflection
|
||
|
|
||
|
The `Guzzle\Inflection` namespace has been removed. This is not a core concern
|
||
|
of Guzzle.
|
||
|
|
||
|
## Iterator
|
||
|
|
||
|
The `Guzzle\Iterator` namespace has been removed.
|
||
|
|
||
|
- `Guzzle\Iterator\AppendIterator`, `Guzzle\Iterator\ChunkedIterator`, and
|
||
|
`Guzzle\Iterator\MethodProxyIterator` are nice, but not a core requirement of
|
||
|
Guzzle itself.
|
||
|
- `Guzzle\Iterator\FilterIterator` is no longer needed because an equivalent
|
||
|
class is shipped with PHP 5.4.
|
||
|
- `Guzzle\Iterator\MapIterator` is not really needed when using PHP 5.5 because
|
||
|
it's easier to just wrap an iterator in a generator that maps values.
|
||
|
|
||
|
For a replacement of these iterators, see https://github.com/nikic/iter
|
||
|
|
||
|
## Log
|
||
|
|
||
|
The LogPlugin has moved to https://github.com/guzzle/log-subscriber. The
|
||
|
`Guzzle\Log` namespace has been removed. Guzzle now relies on
|
||
|
`Psr\Log\LoggerInterface` for all logging. The MessageFormatter class has been
|
||
|
moved to `GuzzleHttp\Subscriber\Log\Formatter`.
|
||
|
|
||
|
## Parser
|
||
|
|
||
|
The `Guzzle\Parser` namespace has been removed. This was previously used to
|
||
|
make it possible to plug in custom parsers for cookies, messages, URI
|
||
|
templates, and URLs; however, this level of complexity is not needed in Guzzle
|
||
|
so it has been removed.
|
||
|
|
||
|
- Cookie: Cookie parsing logic has been moved to
|
||
|
`GuzzleHttp\Cookie\SetCookie::fromString`.
|
||
|
- Message: Message parsing logic for both requests and responses has been moved
|
||
|
to `GuzzleHttp\Message\MessageFactory::fromMessage`. Message parsing is only
|
||
|
used in debugging or deserializing messages, so it doesn't make sense for
|
||
|
Guzzle as a library to add this level of complexity to parsing messages.
|
||
|
- UriTemplate: URI template parsing has been moved to
|
||
|
`GuzzleHttp\UriTemplate`. The Guzzle library will automatically use the PECL
|
||
|
URI template library if it is installed.
|
||
|
- Url: URL parsing is now performed in `GuzzleHttp\Url::fromString` (previously
|
||
|
it was `Guzzle\Http\Url::factory()`). If custom URL parsing is necessary,
|
||
|
then developers are free to subclass `GuzzleHttp\Url`.
|
||
|
|
||
|
## Plugin
|
||
|
|
||
|
The `Guzzle\Plugin` namespace has been renamed to `GuzzleHttp\Subscriber`.
|
||
|
Several plugins are shipping with the core Guzzle library under this namespace.
|
||
|
|
||
|
- `GuzzleHttp\Subscriber\Cookie`: Replaces the old CookiePlugin. Cookie jar
|
||
|
code has moved to `GuzzleHttp\Cookie`.
|
||
|
- `GuzzleHttp\Subscriber\History`: Replaces the old HistoryPlugin.
|
||
|
- `GuzzleHttp\Subscriber\HttpError`: Throws errors when a bad HTTP response is
|
||
|
received.
|
||
|
- `GuzzleHttp\Subscriber\Mock`: Replaces the old MockPlugin.
|
||
|
- `GuzzleHttp\Subscriber\Prepare`: Prepares the body of a request just before
|
||
|
sending. This subscriber is attached to all requests by default.
|
||
|
- `GuzzleHttp\Subscriber\Redirect`: Replaces the RedirectPlugin.
|
||
|
|
||
|
The following plugins have been removed (third-parties are free to re-implement
|
||
|
these if needed):
|
||
|
|
||
|
- `GuzzleHttp\Plugin\Async` has been removed.
|
||
|
- `GuzzleHttp\Plugin\CurlAuth` has been removed.
|
||
|
- `GuzzleHttp\Plugin\ErrorResponse\ErrorResponsePlugin` has been removed. This
|
||
|
functionality should instead be implemented with event listeners that occur
|
||
|
after normal response parsing occurs in the guzzle/command package.
|
||
|
|
||
|
The following plugins are not part of the core Guzzle package, but are provided
|
||
|
in separate repositories:
|
||
|
|
||
|
- `Guzzle\Http\Plugin\BackoffPlugin` has been rewritten to be much simpler
|
||
|
to build custom retry policies using simple functions rather than various
|
||
|
chained classes. See: https://github.com/guzzle/retry-subscriber
|
||
|
- `Guzzle\Http\Plugin\Cache\CachePlugin` has moved to
|
||
|
https://github.com/guzzle/cache-subscriber
|
||
|
- `Guzzle\Http\Plugin\Log\LogPlugin` has moved to
|
||
|
https://github.com/guzzle/log-subscriber
|
||
|
- `Guzzle\Http\Plugin\Md5\Md5Plugin` has moved to
|
||
|
https://github.com/guzzle/message-integrity-subscriber
|
||
|
- `Guzzle\Http\Plugin\Mock\MockPlugin` has moved to
|
||
|
`GuzzleHttp\Subscriber\MockSubscriber`.
|
||
|
- `Guzzle\Http\Plugin\Oauth\OauthPlugin` has moved to
|
||
|
https://github.com/guzzle/oauth-subscriber
|
||
|
|
||
|
## Service
|
||
|
|
||
|
The service description layer of Guzzle has moved into two separate packages:
|
||
|
|
||
|
- http://github.com/guzzle/command Provides a high level abstraction over web
|
||
|
services by representing web service operations using commands.
|
||
|
- http://github.com/guzzle/guzzle-services Provides an implementation of
|
||
|
guzzle/command that provides request serialization and response parsing using
|
||
|
Guzzle service descriptions.
|
||
|
|
||
|
## Stream
|
||
|
|
||
|
Stream have moved to a separate package available at
|
||
|
https://github.com/guzzle/streams.
|
||
|
|
||
|
`Guzzle\Stream\StreamInterface` has been given a large update to cleanly take
|
||
|
on the responsibilities of `Guzzle\Http\EntityBody` and
|
||
|
`Guzzle\Http\EntityBodyInterface` now that they have been removed. The number
|
||
|
of methods implemented by the `StreamInterface` has been drastically reduced to
|
||
|
allow developers to more easily extend and decorate stream behavior.
|
||
|
|
||
|
## Removed methods from StreamInterface
|
||
|
|
||
|
- `getStream` and `setStream` have been removed to better encapsulate streams.
|
||
|
- `getMetadata` and `setMetadata` have been removed in favor of
|
||
|
`GuzzleHttp\Stream\MetadataStreamInterface`.
|
||
|
- `getWrapper`, `getWrapperData`, `getStreamType`, and `getUri` have all been
|
||
|
removed. This data is accessible when
|
||
|
using streams that implement `GuzzleHttp\Stream\MetadataStreamInterface`.
|
||
|
- `rewind` has been removed. Use `seek(0)` for a similar behavior.
|
||
|
|
||
|
## Renamed methods
|
||
|
|
||
|
- `detachStream` has been renamed to `detach`.
|
||
|
- `feof` has been renamed to `eof`.
|
||
|
- `ftell` has been renamed to `tell`.
|
||
|
- `readLine` has moved from an instance method to a static class method of
|
||
|
`GuzzleHttp\Stream\Stream`.
|
||
|
|
||
|
## Metadata streams
|
||
|
|
||
|
`GuzzleHttp\Stream\MetadataStreamInterface` has been added to denote streams
|
||
|
that contain additional metadata accessible via `getMetadata()`.
|
||
|
`GuzzleHttp\Stream\StreamInterface::getMetadata` and
|
||
|
`GuzzleHttp\Stream\StreamInterface::setMetadata` have been removed.
|
||
|
|
||
|
## StreamRequestFactory
|
||
|
|
||
|
The entire concept of the StreamRequestFactory has been removed. The way this
|
||
|
was used in Guzzle 3 broke the actual interface of sending streaming requests
|
||
|
(instead of getting back a Response, you got a StreamInterface). Streaming
|
||
|
PHP requests are now implemented through the `GuzzleHttp\Adapter\StreamAdapter`.
|
||
|
|
||
|
3.6 to 3.7
|
||
|
----------
|
||
|
|
||
|
### Deprecations
|
||
|
|
||
|
- You can now enable E_USER_DEPRECATED warnings to see if you are using any deprecated methods.:
|
||
|
|
||
|
```php
|
||
|
\Guzzle\Common\Version::$emitWarnings = true;
|
||
|
```
|
||
|
|
||
|
The following APIs and options have been marked as deprecated:
|
||
|
|
||
|
- Marked `Guzzle\Http\Message\Request::isResponseBodyRepeatable()` as deprecated. Use `$request->getResponseBody()->isRepeatable()` instead.
|
||
|
- Marked `Guzzle\Http\Message\Request::canCache()` as deprecated. Use `Guzzle\Plugin\Cache\DefaultCanCacheStrategy->canCacheRequest()` instead.
|
||
|
- Marked `Guzzle\Http\Message\Request::canCache()` as deprecated. Use `Guzzle\Plugin\Cache\DefaultCanCacheStrategy->canCacheRequest()` instead.
|
||
|
- Marked `Guzzle\Http\Message\Request::setIsRedirect()` as deprecated. Use the HistoryPlugin instead.
|
||
|
- Marked `Guzzle\Http\Message\Request::isRedirect()` as deprecated. Use the HistoryPlugin instead.
|
||
|
- Marked `Guzzle\Cache\CacheAdapterFactory::factory()` as deprecated
|
||
|
- Marked `Guzzle\Service\Client::enableMagicMethods()` as deprecated. Magic methods can no longer be disabled on a Guzzle\Service\Client.
|
||
|
- Marked `Guzzle\Parser\Url\UrlParser` as deprecated. Just use PHP's `parse_url()` and percent encode your UTF-8.
|
||
|
- Marked `Guzzle\Common\Collection::inject()` as deprecated.
|
||
|
- Marked `Guzzle\Plugin\CurlAuth\CurlAuthPlugin` as deprecated. Use
|
||
|
`$client->getConfig()->setPath('request.options/auth', array('user', 'pass', 'Basic|Digest|NTLM|Any'));` or
|
||
|
`$client->setDefaultOption('auth', array('user', 'pass', 'Basic|Digest|NTLM|Any'));`
|
||
|
|
||
|
3.7 introduces `request.options` as a parameter for a client configuration and as an optional argument to all creational
|
||
|
request methods. When paired with a client's configuration settings, these options allow you to specify default settings
|
||
|
for various aspects of a request. Because these options make other previous configuration options redundant, several
|
||
|
configuration options and methods of a client and AbstractCommand have been deprecated.
|
||
|
|
||
|
- Marked `Guzzle\Service\Client::getDefaultHeaders()` as deprecated. Use `$client->getDefaultOption('headers')`.
|
||
|
- Marked `Guzzle\Service\Client::setDefaultHeaders()` as deprecated. Use `$client->setDefaultOption('headers/{header_name}', 'value')`.
|
||
|
- Marked 'request.params' for `Guzzle\Http\Client` as deprecated. Use `$client->setDefaultOption('params/{param_name}', 'value')`
|
||
|
- Marked 'command.headers', 'command.response_body' and 'command.on_complete' as deprecated for AbstractCommand. These will work through Guzzle 4.0
|
||
|
|
||
|
$command = $client->getCommand('foo', array(
|
||
|
'command.headers' => array('Test' => '123'),
|
||
|
'command.response_body' => '/path/to/file'
|
||
|
));
|
||
|
|
||
|
// Should be changed to:
|
||
|
|
||
|
$command = $client->getCommand('foo', array(
|
||
|
'command.request_options' => array(
|
||
|
'headers' => array('Test' => '123'),
|
||
|
'save_as' => '/path/to/file'
|
||
|
)
|
||
|
));
|
||
|
|
||
|
### Interface changes
|
||
|
|
||
|
Additions and changes (you will need to update any implementations or subclasses you may have created):
|
||
|
|
||
|
- Added an `$options` argument to the end of the following methods of `Guzzle\Http\ClientInterface`:
|
||
|
createRequest, head, delete, put, patch, post, options, prepareRequest
|
||
|
- Added an `$options` argument to the end of `Guzzle\Http\Message\Request\RequestFactoryInterface::createRequest()`
|
||
|
- Added an `applyOptions()` method to `Guzzle\Http\Message\Request\RequestFactoryInterface`
|
||
|
- Changed `Guzzle\Http\ClientInterface::get($uri = null, $headers = null, $body = null)` to
|
||
|
`Guzzle\Http\ClientInterface::get($uri = null, $headers = null, $options = array())`. You can still pass in a
|
||
|
resource, string, or EntityBody into the $options parameter to specify the download location of the response.
|
||
|
- Changed `Guzzle\Common\Collection::__construct($data)` to no longer accepts a null value for `$data` but a
|
||
|
default `array()`
|
||
|
- Added `Guzzle\Stream\StreamInterface::isRepeatable`
|
||
|
- Made `Guzzle\Http\Client::expandTemplate` and `getUriTemplate` protected methods.
|
||
|
|
||
|
The following methods were removed from interfaces. All of these methods are still available in the concrete classes
|
||
|
that implement them, but you should update your code to use alternative methods:
|
||
|
|
||
|
- Removed `Guzzle\Http\ClientInterface::setDefaultHeaders(). Use
|
||
|
`$client->getConfig()->setPath('request.options/headers/{header_name}', 'value')`. or
|
||
|
`$client->getConfig()->setPath('request.options/headers', array('header_name' => 'value'))` or
|
||
|
`$client->setDefaultOption('headers/{header_name}', 'value')`. or
|
||
|
`$client->setDefaultOption('headers', array('header_name' => 'value'))`.
|
||
|
- Removed `Guzzle\Http\ClientInterface::getDefaultHeaders(). Use `$client->getConfig()->getPath('request.options/headers')`.
|
||
|
- Removed `Guzzle\Http\ClientInterface::expandTemplate()`. This is an implementation detail.
|
||
|
- Removed `Guzzle\Http\ClientInterface::setRequestFactory()`. This is an implementation detail.
|
||
|
- Removed `Guzzle\Http\ClientInterface::getCurlMulti()`. This is a very specific implementation detail.
|
||
|
- Removed `Guzzle\Http\Message\RequestInterface::canCache`. Use the CachePlugin.
|
||
|
- Removed `Guzzle\Http\Message\RequestInterface::setIsRedirect`. Use the HistoryPlugin.
|
||
|
- Removed `Guzzle\Http\Message\RequestInterface::isRedirect`. Use the HistoryPlugin.
|
||
|
|
||
|
### Cache plugin breaking changes
|
||
|
|
||
|
- CacheKeyProviderInterface and DefaultCacheKeyProvider are no longer used. All of this logic is handled in a
|
||
|
CacheStorageInterface. These two objects and interface will be removed in a future version.
|
||
|
- Always setting X-cache headers on cached responses
|
||
|
- Default cache TTLs are now handled by the CacheStorageInterface of a CachePlugin
|
||
|
- `CacheStorageInterface::cache($key, Response $response, $ttl = null)` has changed to `cache(RequestInterface
|
||
|
$request, Response $response);`
|
||
|
- `CacheStorageInterface::fetch($key)` has changed to `fetch(RequestInterface $request);`
|
||
|
- `CacheStorageInterface::delete($key)` has changed to `delete(RequestInterface $request);`
|
||
|
- Added `CacheStorageInterface::purge($url)`
|
||
|
- `DefaultRevalidation::__construct(CacheKeyProviderInterface $cacheKey, CacheStorageInterface $cache, CachePlugin
|
||
|
$plugin)` has changed to `DefaultRevalidation::__construct(CacheStorageInterface $cache,
|
||
|
CanCacheStrategyInterface $canCache = null)`
|
||
|
- Added `RevalidationInterface::shouldRevalidate(RequestInterface $request, Response $response)`
|
||

|
||
|
3.5 to 3.6
|
||
|
----------
|
||
|
|
||
|
* Mixed casing of headers are now forced to be a single consistent casing across all values for that header.
|
||
|
* Messages internally use a HeaderCollection object to delegate handling case-insensitive header resolution
|
||
|
* Removed the whole changedHeader() function system of messages because all header changes now go through addHeader().
|
||
|
For example, setHeader() first removes the header using unset on a HeaderCollection and then calls addHeader().
|
||
|
Keeping the Host header and URL host in sync is now handled by overriding the addHeader method in Request.
|
||
|
* Specific header implementations can be created for complex headers. When a message creates a header, it uses a
|
||
|
HeaderFactory which can map specific headers to specific header classes. There is now a Link header and
|
||
|
CacheControl header implementation.
|
||
|
* Moved getLinks() from Response to just be used on a Link header object.
|
||
|
|
||
|
If you previously relied on Guzzle\Http\Message\Header::raw(), then you will need to update your code to use the
|
||
|
HeaderInterface (e.g. toArray(), getAll(), etc.).
|
||
|
|
||
|
### Interface changes
|
||
|
|
||
|
* Removed from interface: Guzzle\Http\ClientInterface::setUriTemplate
|
||
|
* Removed from interface: Guzzle\Http\ClientInterface::setCurlMulti()
|
||
|
* Removed Guzzle\Http\Message\Request::receivedRequestHeader() and implemented this functionality in
|
||
|
Guzzle\Http\Curl\RequestMediator
|
||
|
* Removed the optional $asString parameter from MessageInterface::getHeader(). Just cast the header to a string.
|
||
|
* Removed the optional $tryChunkedTransfer option from Guzzle\Http\Message\EntityEnclosingRequestInterface
|
||
|
* Removed the $asObjects argument from Guzzle\Http\Message\MessageInterface::getHeaders()
|
||
|
|
||
|
### Removed deprecated functions
|
||
|
|
||
|
* Removed Guzzle\Parser\ParserRegister::get(). Use getParser()
|
||
|
* Removed Guzzle\Parser\ParserRegister::set(). Use registerParser().
|
||
|
|
||
|
### Deprecations
|
||
|
|
||
|
* The ability to case-insensitively search for header values
|
||
|
* Guzzle\Http\Message\Header::hasExactHeader
|
||
|
* Guzzle\Http\Message\Header::raw. Use getAll()
|
||
|
* Deprecated cache control specific methods on Guzzle\Http\Message\AbstractMessage. Use the CacheControl header object
|
||
|
instead.
|
||
|
|
||
|
### Other changes
|
||
|
|
||
|
* All response header helper functions return a string rather than mixing Header objects and strings inconsistently
|
||
|
* Removed cURL blacklist support. This is no longer necessary now that Expect, Accept, etc. are managed by Guzzle
|
||
|
directly via interfaces
|
||
|
* Removed the injecting of a request object onto a response object. The methods to get and set a request still exist
|
||
|
but are a no-op until removed.
|
||
|
* Most classes that used to require a `Guzzle\Service\Command\CommandInterface` typehint now request a
|
||
|
`Guzzle\Service\Command\ArrayCommandInterface`.
|
||
|
* Added `Guzzle\Http\Message\RequestInterface::startResponse()` to the RequestInterface to handle injecting a response
|
||
|
on a request while the request is still being transferred
|
||
|
* `Guzzle\Service\Command\CommandInterface` now extends from ToArrayInterface and ArrayAccess
|
||
|
|
||
|
3.3 to 3.4
|
||
|
----------
|
||
|
|
||
|
Base URLs of a client now follow the rules of http://tools.ietf.org/html/rfc3986#section-5.2.2 when merging URLs.
|
||
|
|
||
|
3.2 to 3.3
|
||
|
----------
|
||
|
|
||
|
### Response::getEtag() quote stripping removed
|
||
|
|
||
|
`Guzzle\Http\Message\Response::getEtag()` no longer strips quotes around the ETag response header
|
||
|
|
||
|
### Removed `Guzzle\Http\Utils`
|
||
|
|
||
|
The `Guzzle\Http\Utils` class was removed. This class was only used for testing.
|
||
|
|
||
|
### Stream wrapper and type
|
||
|
|
||
|
`Guzzle\Stream\Stream::getWrapper()` and `Guzzle\Stream\Stream::getStreamType()` are no longer converted to lowercase.
|
||
|
|
||
|
### curl.emit_io became emit_io
|
||
|
|
||
|
Emitting IO events from a RequestMediator is now a parameter that must be set in a request's curl options using the
|
||
|
'emit_io' key. This was previously set under a request's parameters using 'curl.emit_io'
|
||
|
|
||
|
3.1 to 3.2
|
||
|
----------
|
||
|
|
||
|
### CurlMulti is no longer reused globally
|
||
|
|
||
|
Before 3.2, the same CurlMulti object was reused globally for each client. This can cause issue where plugins added
|
||
|
to a single client can pollute requests dispatched from other clients.
|
||
|
|
||
|
If you still wish to reuse the same CurlMulti object with each client, then you can add a listener to the
|
||
|
ServiceBuilder's `service_builder.create_client` event to inject a custom CurlMulti object into each client as it is
|
||
|
created.
|
||
|
|
||
|
```php
|
||
|
$multi = new Guzzle\Http\Curl\CurlMulti();
|
||
|
$builder = Guzzle\Service\Builder\ServiceBuilder::factory('/path/to/config.json');
|
||
|
$builder->addListener('service_builder.create_client', function ($event) use ($multi) {
|
||
|
$event['client']->setCurlMulti($multi);
|
||
|
}
|
||
|
});
|
||
|
```
|
||
|
|
||
|
### No default path
|
||
|
|
||
|
URLs no longer have a default path value of '/' if no path was specified.
|
||
|
|
||
|
Before:
|
||
|
|
||
|
```php
|
||
|
$request = $client->get('http://www.foo.com');
|
||
|
echo $request->getUrl();
|
||
|
// >> http://www.foo.com/
|
||
|
```
|
||
|
|
||
|
After:
|
||
|
|
||
|
```php
|
||
|
$request = $client->get('http://www.foo.com');
|
||
|
echo $request->getUrl();
|
||
|
// >> http://www.foo.com
|
||
|
```
|
||
|
|
||
|
### Less verbose BadResponseException
|
||
|
|
||
|
The exception message for `Guzzle\Http\Exception\BadResponseException` no longer contains the full HTTP request and
|
||
|
response information. You can, however, get access to the request and response object by calling `getRequest()` or
|
||
|
`getResponse()` on the exception object.
|
||
|
|
||
|
### Query parameter aggregation
|
||
|
|
||
|
Multi-valued query parameters are no longer aggregated using a callback function. `Guzzle\Http\Query` now has a
|
||
|
setAggregator() method that accepts a `Guzzle\Http\QueryAggregator\QueryAggregatorInterface` object. This object is
|
||
|
responsible for handling the aggregation of multi-valued query string variables into a flattened hash.
|
||
|
|
||
|
2.8 to 3.x
|
||
|
----------
|
||
|
|
||
|
### Guzzle\Service\Inspector
|
||
|
|
||
|
Change `\Guzzle\Service\Inspector::fromConfig` to `\Guzzle\Common\Collection::fromConfig`
|
||
|
|
||
|
**Before**
|
||
|
|
||
|
```php
|
||
|
use Guzzle\Service\Inspector;
|
||
|
|
||
|
class YourClient extends \Guzzle\Service\Client
|
||
|
{
|
||
|
public static function factory($config = array())
|
||
|
{
|
||
|
$default = array();
|
||
|
$required = array('base_url', 'username', 'api_key');
|
||
|
$config = Inspector::fromConfig($config, $default, $required);
|
||
|
|
||
|
$client = new self(
|
||
|
$config->get('base_url'),
|
||
|
$config->get('username'),
|
||
|
$config->get('api_key')
|
||
|
);
|
||
|
$client->setConfig($config);
|
||
|
|
||
|
$client->setDescription(ServiceDescription::factory(__DIR__ . DIRECTORY_SEPARATOR . 'client.json'));
|
||
|
|
||
|
return $client;
|
||
|
}
|
||
|
```
|
||
|
|
||
|
**After**
|
||
|
|
||
|
```php
|
||
|
use Guzzle\Common\Collection;
|
||
|
|
||
|
class YourClient extends \Guzzle\Service\Client
|
||
|
{
|
||
|
public static function factory($config = array())
|
||
|
{
|
||
|
$default = array();
|
||
|
$required = array('base_url', 'username', 'api_key');
|
||
|
$config = Collection::fromConfig($config, $default, $required);
|
||
|
|
||
|
$client = new self(
|
||
|
$config->get('base_url'),
|
||
|
$config->get('username'),
|
||
|
$config->get('api_key')
|
||
|
);
|
||
|
$client->setConfig($config);
|
||
|
|
||
|
$client->setDescription(ServiceDescription::factory(__DIR__ . DIRECTORY_SEPARATOR . 'client.json'));
|
||
|
|
||
|
return $client;
|
||
|
}
|
||
|
```
|
||
|
|
||
|

### Guzzle\Service\Description\ServiceDescription
|
||
|
|
||
|
Commands are now called Operations
|
||
|
|
||
|
**Before**
|
||
|
|
||
|
```php
|
||
|
use Guzzle\Service\Description\ServiceDescription;
|
||
|
|
||
|
$sd = new ServiceDescription();
|
||
|
$sd->getCommands(); // @returns ApiCommandInterface[]
|
||
|
$sd->hasCommand($name);
|
||
|
$sd->getCommand($name); // @returns ApiCommandInterface|null
|
||
|
$sd->addCommand($command); // @param ApiCommandInterface $command
|
||
|
```
|
||
|
|
||
|
**After**
|
||
|
|
||
|
```php
|
||
|
use Guzzle\Service\Description\ServiceDescription;
|
||
|
|
||
|
$sd = new ServiceDescription();
|
||
|
$sd->getOperations(); // @returns OperationInterface[]
|
||
|
$sd->hasOperation($name);
|
||
|
$sd->getOperation($name); // @returns OperationInterface|null
|
||
|
$sd->addOperation($operation); // @param OperationInterface $operation
|
||
|
```
|
||
|
|
||
|
### Guzzle\Common\Inflection\Inflector
|
||
|
|
||
|
Namespace is now `Guzzle\Inflection\Inflector`
|
||
|
|
||
|
### Guzzle\Http\Plugin
|
||
|
|
||
|
Namespace is now `Guzzle\Plugin`. Many other changes occur within this namespace and are detailed in their own sections below.
|
||
|
|
||
|
### Guzzle\Http\Plugin\LogPlugin and Guzzle\Common\Log
|
||
|
|
||
|
Now `Guzzle\Plugin\Log\LogPlugin` and `Guzzle\Log` respectively.
|
||
|
|
||
|
**Before**
|
||
|
|
||
|
```php
|
||
|
use Guzzle\Common\Log\ClosureLogAdapter;
|
||
|
use Guzzle\Http\Plugin\LogPlugin;
|
||
|
|
||
|
/** @var \Guzzle\Http\Client */
|
||
|
$client;
|
||
|
|
||
|
// $verbosity is an integer indicating desired message verbosity level
|
||
|
$client->addSubscriber(new LogPlugin(new ClosureLogAdapter(function($m) { echo $m; }, $verbosity = LogPlugin::LOG_VERBOSE);
|
||
|
```
|
||
|
|
||
|
**After**
|
||
|
|
||
|
```php
|
||
|
use Guzzle\Log\ClosureLogAdapter;
|
||
|
use Guzzle\Log\MessageFormatter;
|
||
|
use Guzzle\Plugin\Log\LogPlugin;
|
||
|
|
||
|
/** @var \Guzzle\Http\Client */
|
||
|
$client;
|
||
|
|
||
|
// $format is a string indicating desired message format -- @see MessageFormatter
|
||
|
$client->addSubscriber(new LogPlugin(new ClosureLogAdapter(function($m) { echo $m; }, $format = MessageFormatter::DEBUG_FORMAT);
|
||
|
```
|
||
|
|
||
|
### Guzzle\Http\Plugin\CurlAuthPlugin
|
||
|
|
||
|
Now `Guzzle\Plugin\CurlAuth\CurlAuthPlugin`.
|
||
|
|
||
|
### Guzzle\Http\Plugin\ExponentialBackoffPlugin
|
||
|
|
||
|
Now `Guzzle\Plugin\Backoff\BackoffPlugin`, and other changes.
|
||
|
|
||
|
**Before**
|
||
|
|
||
|
```php
|
||
|
use Guzzle\Http\Plugin\ExponentialBackoffPlugin;
|
||
|
|
||
|
$backoffPlugin = new ExponentialBackoffPlugin($maxRetries, array_merge(
|
||
|
ExponentialBackoffPlugin::getDefaultFailureCodes(), array(429)
|
||
|
));
|
||
|
|
||
|
$client->addSubscriber($backoffPlugin);
|
||
|
```
|
||
|
|
||
|
**After**
|
||
|
|
||
|
```php
|
||
|
use Guzzle\Plugin\Backoff\BackoffPlugin;
|
||
|
use Guzzle\Plugin\Backoff\HttpBackoffStrategy;
|
||
|
|
||
|
// Use convenient factory method instead -- see implementation for ideas of what
|
||
|
// you can do with chaining backoff strategies
|
||
|
$backoffPlugin = BackoffPlugin::getExponentialBackoff($maxRetries, array_merge(
|
||
|
HttpBackoffStrategy::getDefaultFailureCodes(), array(429)
|
||
|
));
|
||
|
$client->addSubscriber($backoffPlugin);
|
||
|
```
|
||
|
|
||
|
### Known Issues
|
||
|
|
||
|
#### [BUG] Accept-Encoding header behavior changed unintentionally.
|
||
|
|
||
|
(See #217) (Fixed in 09daeb8c666fb44499a0646d655a8ae36456575e)
|
||
|
|
||
|
In version 2.8 setting the `Accept-Encoding` header would set the CURLOPT_ENCODING option, which permitted cURL to
|
||
|
properly handle gzip/deflate compressed responses from the server. In versions affected by this bug this does not happen.
|
||
|
See issue #217 for a workaround, or use a version containing the fix.
|
