◆ 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.

1.19

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.

Note
suhosin.session.encrypt may interfere with this method.
Parameters
array$paramsResult of RequestContext::exportSession()
Returns
ScopedCallback
Exceptions
MWException

◆ msg()

RequestContext::msg (   $key,

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

  • 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
Title$titleTitle to use for the extraneous request
WebRequest | array$requestA WebRequest or data to use for a FauxRequest
