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 211 of file RequestContext.php.

References $title, MediaWiki\Title\Title\canExist(), 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 584 of file RequestContext.php.

References 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

Implements IContextSource.

Definition at line 280 of file RequestContext.php.

◆ getAuthority()

RequestContext::getAuthority ( )

Since: 1.36

Returns: Authority

Implements IContextSource.

Definition at line 371 of file RequestContext.php.

◆ getConfig()

RequestContext::getConfig ( )

Returns: Config

Implements IContextSource.

Definition at line 124 of file RequestContext.php.

◆ getCsrfTokenSet()

RequestContext::getCsrfTokenSet ( )

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

Returns: CsrfTokenSet

Implements MediaWiki\Session\CsrfTokenSetProvider.

Definition at line 594 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 426 of file RequestContext.php.

References $lang, and getUser().

◆ getMain()

static RequestContext::getMain ( )

static

Get the RequestContext object associated with the main request.

Returns: RequestContext

Definition at line 546 of file RequestContext.php.

Referenced by importScopedSession().

◆ 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

Definition at line 560 of file RequestContext.php.

References wfDebug().

◆ getOutput()

RequestContext::getOutput ( )

Returns: OutputPage

Implements IContextSource.

Definition at line 321 of file RequestContext.php.

◆ getRequest()

RequestContext::getRequest ( )

Returns: WebRequest

Returns: User

Implements IContextSource.

Definition at line 341 of file RequestContext.php.

References 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 247 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 199 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 618 of file RequestContext.php.

References $wgRequest, getMain(), User\newFromId(), and User\newFromName().

◆ 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

Definition at line 537 of file RequestContext.php.

References wfMessage().

◆ newExtraneousContext()

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

static

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
