|
|
<p>This milestone could be just this, what's different from any other ActivityPub
|
|
plugin? How is it better than v2's?</p>
|
|
|
|
<p>It's better in how it's organised and extensible. See the examples below to have
|
|
an idea.</p>
|
|
|
|
<p>To extend an Activity properties you do:</p>
|
|
|
|
<pre><code>public function onActivityPubValidateActivityStreamsTwoData(string $type_name, array &$validators): bool {
|
|
if ($type_name === '{Type}') {
|
|
$validators['attribute'] = myValidator::class;
|
|
}
|
|
return Event::next;
|
|
}
|
|
</code></pre>
|
|
|
|
<p>The Validator should be of the form:</p>
|
|
|
|
<pre><code>class myValidator extends Plugin\ActivityPub\Util\ModelValidator
|
|
{
|
|
/**
|
|
* Validate Attribute's value
|
|
*
|
|
* @param mixed $value from JSON's attribute
|
|
* @param mixed $container A {Type}
|
|
* @return bool
|
|
* @throws Exception
|
|
*/
|
|
public function validate($value, $container): bool
|
|
{
|
|
// Validate that container is a {Type}
|
|
Util::subclassOf($container, Type\Extended\Object\{Type}::class, true);
|
|
|
|
return {Validation Result};
|
|
</code></pre>
|
|
|
|
<p>To act on received activities do:</p>
|
|
|
|
<pre><code>public function onActivityPubNew{Type}(&$obj): bool {
|
|
</code></pre>
|
|
|
|
<p>To add information to Activities being federated by ActivityPub do:</p>
|
|
|
|
<pre><code>public function ActivityPubAddActivityStreamsTwoData(string $type_name, &$type): bool {
|
|
</code></pre>
|
|
|
|
<p>To implement an ActivityStreams 2.0 representation do:</p>
|
|
|
|
<pre><code>public function onActivityPubActivityStreamsTwoResponse(string $route, arrray $vars, ?TypeResponse &$response = null): bool {
|
|
if ($route === '{Object route}') {
|
|
$response = ModelResponse::handle($vars[{Object}]);
|
|
return Event::stop;
|
|
}
|
|
return Event::next;
|
|
}
|
|
</code></pre>
