Member Function Documentation

RequestContext::canUseWikiPage ( )

Check whether a WikiPage object can be get with getWikiPage().

Callers should expect that an exception is thrown from getWikiPage() if this method returns false.

Since: 1.19

Returns: bool

Implements IContextSource.

Definition at line 208 of file RequestContext.php.

References Title\canExist(), and getTitle().

RequestContext::exportSession ( )

Export the resolved user IP, HTTP headers, user ID, and session ID.

The result will be reasonably sized to allow for serialization.

Returns: array

Since: 1.21

Implements IContextSource.

References MediaWiki\Session\SessionManager\getGlobalSession(), getRequest(), and getUser().

RequestContext::getConfig ( )

Get the Config object.

Returns: Config

Implements IContextSource.

RequestContext::getLanguage ( )

Get the Language object.

Initialization of user or request objects can depend on this.

Returns: Language

Get the RequestContext object associated with the main request and gives a warning to the log, to find places, where a context maybe is missing.

Parameters

RequestContext::getStats ( )

Get the Stats object.

Deprecated:: since 1.27 use a StatsdDataFactory from MediaWikiServices (preferably injected)

Returns: StatsdDataFactory

Implements IContextSource.

RequestContext::getTiming ( )

Get the timing object.

Returns: Timing

RequestContext::getWikiPage ( )

Get the WikiPage object.

May throw an exception if there's no Title object set or the Title object belongs to a special namespace that doesn't have WikiPage, so use first canUseWikiPage() to check whether this method can be called safely.

Since: 1.19

Exceptions

Returns: WikiPage

static RequestContext::importScopedSession ( array $params )

static

Import an client IP address, HTTP headers, user ID, and session ID.

This sets the current session, $wgUser, and $wgRequest from $params. Once the return value falls out of scope, the old context is restored. This method should only be called in contexts where there is no session ID or end user receiving the response (CLI or HTTP job runners). This is partly enforced, and is done so to avoid leaking cookies if certain error conditions arise.

This is useful when background scripts inherit context when acting on behalf of a user. In general the 'sessionId' parameter should be set to an empty string unless session importing is truly needed. This feature is somewhat deprecated.

Note: suhosin.session.encrypt may interfere with this method.

Parameters

array $params Result of RequestContext::exportSession()

Returns: ScopedCallback

Exceptions

MWException
