@page apiroot API Root
|
|
|
|
The URLs for methods referred to in this API documentation are
|
|
relative to the StatusNet API root. The API root is determined by the
|
|
site's @b server and @b path variables, which are generally specified
|
|
in config.php. For example:
|
|
|
|
@code
|
|
$config['site']['server'] = 'example.org';
|
|
$config['site']['path'] = 'statusnet'
|
|
@endcode
|
|
|
|
The pattern for a site's API root is: @c protocol://server/path/api E.g:
|
|
|
|
@c http://example.org/statusnet/api
|
|
|
|
The @b path can be empty. In that case the API root would simply be:
|
|
|
|
@c http://example.org/api
|
|
