Detailed Description

This is the main API class, used for both external and internal processing.

When executed, it will create the requested formatter object, instantiate and execute an object associated with the needed action, and use formatter to print results. In case of an exception, an error message will be printed using the same formatter.

To use API from another application, run it using FauxRequest object, in which case any internal exceptions will not be handled but passed up to the caller. After successful execution, use getResult() for the resulting data.

Stability: newable
Note
marked as newable in 1.35 for lack of a better alternative, but should use a factory in the future.

Constructor & Destructor Documentation

◆ __construct()

ApiMain::__construct ( $context = null,
$enableWrite = false )

Constructs an instance of ApiMain that utilizes the module and format specified by $request.

Stability: stable
to call
Parameters
IContextSource | WebRequest | null$contextIf this is an instance of FauxRequest, errors are thrown and no printing occurs
bool$enableWriteShould be set to true if the api may modify data

Member Function Documentation

◆ addRequestedFields()

ApiMain::addRequestedFields ( $force = [])
protected

Add requested fields to the result.

Parameters
string[]$forceWhich fields to force even if not requested. Accepted values are:
  • servedby

Definition at line 1423 of file ApiMain.php.

References wfHostname(), and wfTimestamp().

◆ canApiHighLimits()

ApiMain::canApiHighLimits ( )

Check whether the current user is allowed to use high limits.

Returns
bool

Definition at line 2411 of file ApiMain.php.

References getAuthority().

◆ checkAsserts()

ApiMain::checkAsserts ( $params)
protected

Check asserts of the user's rights.

Parameters
array$params

Definition at line 1797 of file ApiMain.php.

References getAuthority(), getUser(), and wfEscapeWikiText().

◆ checkConditionalRequestHeaders()

ApiMain::checkConditionalRequestHeaders ( $module)
protected

Check selected RFC 7232 precondition headers.

RFC 7232 envisions a particular model where you send your request to "a resource", and for write requests that you can read "the resource" by changing the method to GET. When the API receives a GET request, it works out even though "the resource" from RFC 7232's perspective might be many resources from MediaWiki's perspective. But it totally fails for a POST, since what HTTP sees as "the resource" is probably just "/api.php" with all the interesting bits in the body.

Therefore, we only support RFC 7232 precondition headers for GET (and HEAD). That means we don't need to bother with If-Match and If-Unmodified-Since since they only apply to modification requests.

And since we don't support Range, If-Range is ignored too.

◆ setCacheControl()

ApiMain::setCacheControl ( $directives)

Set directives (key/value pairs) for the Cache-Control header.

Boolean values will be formatted as such, by including or omitting without an equals sign.

Cache control values set here will only be used if the cache mode is not private, see setCacheMode().

Parameters
array$directives

Definition at line 820 of file ApiMain.php.

◆ setCacheMaxAge()

ApiMain::setCacheMaxAge ( $maxage)

Set how long the response should be cached.

Parameters
int$maxage

Definition at line 743 of file ApiMain.php.

◆ setCacheMode()

ApiMain::setCacheMode ( $mode)

Set the type of caching headers which will be sent.

Parameters
string$modeOne of:
  • 'public': Cache this object in public caches, if the maxage or smaxage parameter is set, or if setCacheMaxAge() was called. If a maximum age is not provided by any of these means, the object will be private.
  • 'private': Cache this object only in private client-side caches.
  • 'anon-public-user-private': Make this object cacheable for logged-out users, but private for logged-in users. IMPORTANT: If this is set, it must be set consistently for a given URL, it cannot be set differently depending on things like the contents of the database, or whether the user is logged in.

If the wiki does not allow anonymous users to read it, the mode set here will be ignored, and private caching headers will always be sent. In other words, the "public" mode is equivalent to saying that the data sent is as public as a page view.

For user-dependent data, the private mode should generally be used. The anon-public-user-private mode should only be used where there is a particularly good performance reason for caching the anonymous response, but where the response to logged-in users may differ, or may contain private data.

If this function is never called, then the default will be the private mode.
