Detailed Description

Group all the pieces relevant to the context of a request into one instance.

Stability: newable

Note: marked as newable in 1.35 for lack of a better alternative, but should use a factory in the future and should be narrowed down to not expose heavy weight objects.

Member Function Documentation

◆ canUseWikiPage()

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 210 of file RequestContext.php.

References $title, and getTitle().

◆ exportSession()

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.

Definition at line 583 of file RequestContext.php.

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

◆ getActionName()

RequestContext::getActionName ( )

Get the action name for the current web request.

This generally returns "view" if the current request or process is not for a skinned index.php web request (e.g. load.php, thumb.php, job runner, CLI, API).

Warning: This must not be called before or during the Setup.php phase, and may cause an error or warning if called too early.

Since: 1.38

Returns: string Action

RequestContext::getAuthority ( )

Since: 1.36

RequestContext::getCsrfTokenSet ( )

Get a set of CSRF tokens to obtain and match specific tokens.

Returns: CsrfTokenSet

Implements MediaWiki\Session\CsrfTokenSetProvider.

Definition at line 593 of file RequestContext.php.

◆ getLanguage()

RequestContext::getLanguage ( )

Get the Language object.

Initialization of user or request objects can depend on this.

Returns: Language

Exceptions

LogicException

Since: 1.19

Implements IContextSource.

Definition at line 425 of file RequestContext.php.

References MediaWiki\Rest\Handler\getRequest(), and getUser().

◆ getMain()

static RequestContext::getMain ( )

static

Get the RequestContext object associated with the main request.

Returns: RequestContext

◆ getMainAndWarn()

static RequestContext::getMainAndWarn ( $func = __METHOD__ )

static

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

string $func

Returns: RequestContext

Since: 1.24

◆ getOutput()

RequestContext::getOutput ( )

Returns: OutputPage

Implements IContextSource.

Definition at line 320 of file RequestContext.php.

◆ getRequest()

RequestContext::getRequest ( )

Returns: WebRequest

Implements IContextSource.

Definition at line 141 of file RequestContext.php.

◆ getSkin()

RequestContext::getSkin ( )

Returns: Skin

Implements IContextSource.

◆ getTiming()

RequestContext::getTiming ( )

Returns: Timing

Implements IContextSource.

◆ getTitle()

RequestContext::getTitle ( )

Returns: Title|null

Implements IContextSource.

Definition at line 178 of file RequestContext.php.

◆ getUser()

RequestContext::getUser ( )

Returns: User

Implements IContextSource.

Definition at line 340 of file RequestContext.php.

References MediaWiki\Rest\Handler\getRequest(), and User\newFromSession().

◆ getWikiPage()

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

MWException

Returns: WikiPage

Implements IContextSource.

Definition at line 246 of file RequestContext.php.

References $title, and getTitle().

◆ hasTitle()

RequestContext::hasTitle ( )

Check, if a Title object is set.

Since: 1.25

Returns: bool

Definition at line 198 of file RequestContext.php.

Referenced by setWikiPage().

◆ importScopedSession()

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.

Parameters

array $params Result of RequestContext::exportSession()

Returns: ScopedCallback

Exceptions

MWException

Since: 1.21

Definition at line 617 of file RequestContext.php.

References $wgRequest, getMain(), User\newFromId(), User\newFromName(), and MediaWiki\Session\SessionManager\singleton().

◆ msg()

RequestContext::msg	(	$key,
		$params
	)

Get a Message object with context set Parameters are the same as wfMessage()

Parameters

string \| string[] \| MessageSpecifier	$key	Message key, or array of keys, or a MessageSpecifier.
	mixed	...$params

Returns: Message

Implements MessageLocalizer.

Definition at line 536 of file RequestContext.php.

References wfMessage().

◆ newExtraneousContext()

static RequestContext::newExtraneousContext	(	Title	$title,
			$request = `[]`
	)

static

Create a new extraneous context.

The context is filled with information external to the current session.

Title is specified by argument
Request is a MediaWiki\Request\FauxRequest, or a MediaWiki\Request\FauxRequest can be specified by argument
User is an anonymous user, for separation IPv4 localhost is used
Language will be based on the anonymous user and request, may be content language or a uselang param in the fauxrequest data may change the lang
Skin will be based on the anonymous user, should be the wiki's default skin

Parameters
