◆ getMethod()

Referenced by wasPosted().

◆ getPathInfo()

static WebRequest::getPathInfo ( $want = 'all' )

staticprotected

Extract relevant query arguments from the http request uri's path to be merged with the normal php provided query arguments.

Tries to use the REQUEST_URI data if available and parses it according to the wiki's configuration looking for any known pattern.

If the REQUEST_URI is not provided we'll fall back on the PATH_INFO provided by the server if any and use that to set a 'title' parameter.

This internal method handles many odd cases and is tailored specifically for used by WebRequest::interpolateTitle, for index.php requests. Consider using WebRequest::getRequestPathSuffix for other path-related use cases.

Parameters

string $want If this is not 'all', then the function will return an empty array if it determines that the URL is inside a rewrite path.

Returns: string[] Any query arguments found in path matches.

Exceptions

FatalError If invalid routes are configured (T48998)

◆ getVal()

WebRequest::getVal	(	$name,
		$default = `null`
	)

Fetch a text string and partially normalized it.

Use of this method is discouraged. It doesn't normalize line breaks and defaults to null instead of the empty string. Instead:

Use {
See also
getText} when reading user input or form fields that are expected to contain non-ASCII characters.
Use {
See also
getRawVal} when reading ASCII strings, such as parameters used to select predefined behaviour in the software.
Array values are discarded for security reasons. Use {
See also
getArray} or {

getIntArray}.

Parameters

string $name

string | null $default

Returns
string|null The input value, or $default if none set

◆ hasSafeMethod()

WebRequest::hasSafeMethod ( )

Check if this request uses a "safe" HTTP method.

Safe methods are verbs (e.g. GET/HEAD/OPTIONS) used for obtaining content. Such requests are not expected to mutate content, especially in ways attributable to the client. Verbs like POST and PUT are typical of non-safe requests which often change content.

Returns: bool

See also: https://tools.ietf.org/html/rfc7231#section-4.2.1; https://www.w3.org/Protocols/rfc2616/rfc2616-sec9.html

◆ initHeaders()

WebRequest::initHeaders ( )

protected

Initialise the header list.

Referenced by getAllHeaders(), and getHeader().

◆ interpolateTitle()

WebRequest::interpolateTitle ( )

Check for title, action, and/or variant data in the URL and interpolate it into the GET variables.

This should only be run after the content language is available, as we may need the list of language variants to determine available variant URLs.

Definition at line 377 of file WebRequest.php.

References $matches.

◆ isSafeRequest()

WebRequest::isSafeRequest ( )

Whether this request should be identified as being "safe".

This means that the client is not requesting any state changes and that database writes are not inherently required. Ideally, no visible updates would happen at all. If they must, then they should not be publicly attributed to the end user.

In more detail:

Cache populations and refreshes MAY occur.
Private user session updates and private server logging MAY occur.
Updates to private viewing activity data MAY occur via DeferredUpdates.
Other updates SHOULD NOT occur (e.g. modifying content assets).

Returns: bool

◆ markAsSafeRequest()

WebRequest::markAsSafeRequest ( )

Mark this request as identified as being nullipotent even if it is a POST request.

POST requests are often used due to the need for a client payload, even if the request is otherwise equivalent to a "safe method" request.

See also: https://tools.ietf.org/html/rfc7231#section-4.2.1; https://www.w3.org/Protocols/rfc2616/rfc2616-sec9.html
