Public Member Functions
	__construct (RevisionLookup $revisionLookup, ParserFactory $parserFactory)

	execute ()
	Execute the handler.

	getParamSettings ()
	Fetch ParamValidator settings for parameters.

	needsWriteAccess ()
	Indicates whether this route requires write access to the wiki.Handlers may override this method to return false if and only if the operation they implement is "safe" per RFC 7231 section 4.2.1. A handler's operation is "safe" if it is essentially read-only, i.e. the client does not request nor expect any state change that would be observable in the responses to future requests.Implementations of this method must always return the same value, regardless of the parameters passed to the constructor or system state.Handlers for GET, HEAD, OPTIONS, and TRACE requests should each implement a "safe" operation. Handlers of PUT and DELETE requests should each implement a non-"safe" operation. Note that handlers of POST requests can implement a "safe" operation, particularly in the case where large input parameters are required.The information provided by this method is used to perform basic authorization checks and to determine whether cross-origin requests are safe. Stability: stable to override Returns bool

Constructor & Destructor Documentation

◆ __construct()

MediaWiki\Rest\Handler\CompareHandler::__construct	(	RevisionLookup	$revisionLookup,
		ParserFactory	$parserFactory )

Definition at line 28 of file CompareHandler.php.

Member Function Documentation

◆ execute()

MediaWiki\Rest\Handler\CompareHandler::execute ( )

Execute the handler.

This is called after parameter validation. The return value can either be a Response or any type accepted by ResponseFactory::createFromReturnValue().

To automatically construct an error response, execute() should throw a \MediaWiki\Rest\HttpException. Such exceptions will not be logged like a normal exception.

If execute() throws any other kind of exception, the exception will be logged and a generic 500 error page will be shown.

Stability: stable: to override

Returns: mixed

Reimplemented from MediaWiki\Rest\Handler.

Definition at line 36 of file CompareHandler.php.

References MediaWiki\Rest\Handler\getAuthority(), and MediaWiki\Rest\Handler\getResponseFactory().

◆ generateResponseSpec()

MediaWiki\Rest\Handler\CompareHandler::generateResponseSpec ( string $method )

protected

Returns an OpenAPI Responses Object specification structure as an associative array.

See also: https://swagger.io/specification/#responses-object

By default, this will contain basic information response for status 200, 400, and 500. The getResponseBodySchema() method is used to determine the structure of the response for status 200.

Subclasses may override this to provide additional information about the structure of responses.

Parameters

string $method The HTTP method to produce a spec for ("get", "post", etc).

Stability: stable: to override

Returns: array

Reimplemented from MediaWiki\Rest\Handler.

Definition at line 195 of file CompareHandler.php.

◆ getParamSettings()

MediaWiki\Rest\Handler\CompareHandler::getParamSettings ( )

Fetch ParamValidator settings for parameters.

Every setting must include self::PARAM_SOURCE to specify which part of the request is to contain the parameter.

Can be used for the request body as well, by setting self::PARAM_SOURCE to "post". Note that the values of "post" parameters will be accessible through getValidatedParams(). "post" parameters are used with form data (application/x-www-form-urlencoded or multipart/form-data).

For "query" parameters, a PARAM_REQUIRED setting of "false" means the caller does not have to supply the parameter. For "path" parameters, the path matcher will always require the caller to supply all path parameters for a route, regardless of the PARAM_REQUIRED setting. However, "path" parameters may be specified in getParamSettings() as non-required to indicate that the handler services multiple routes, some of which may not supply the parameter.

Stability: stable: to override

Returns: array[] Associative array mapping parameter names to ParamValidator settings arrays

Reimplemented from MediaWiki\Rest\Handler.

Definition at line 202 of file CompareHandler.php.

◆ getResponseBodySchemaFileName()

MediaWiki\Rest\Handler\CompareHandler::getResponseBodySchemaFileName ( string $method )

protected

Returns the path and name of a JSON file containing an OpenAPI Schema Object specification structure.

See also: https://swagger.io/specification/#schema-object

Returns null by default. Subclasses with a suitable JSON file should implement this method.

Parameters

string $method The HTTP method to produce a spec for ("get", "post", etc).

Stability: stable: to override

Since: 1.43

Returns: ?string

MediaWiki\Rest\Handler\CompareHandler::needsWriteAccess ( )
