Member Function Documentation

◆ execute()

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

Main execution method, implemented to delegate execution to ApiMain.

Which action API module gets called is controlled by the parameter array returned by getActionModuleParameters(). The response from the action module is passed to mapActionModuleResult(), any ApiUsageException thrown will be converted to a HttpException by throwHttpExceptionForActionModuleError().

Returns: mixed

Reimplemented from MediaWiki\Rest\Handler.

Definition at line 120 of file ActionModuleBasedHandler.php.

◆ getActionModuleParameters()

MediaWiki\Rest\Handler\ActionModuleBasedHandler::getActionModuleParameters ( )

abstractprotected

Maps a REST API request to an action API request.

Implementations typically use information returned by $this->getValidatedBody() and $this->getValidatedParams() to construct the return value.

The return value of this method controls which action module is called by execute().

Returns: array Emulated request parameters to be passed to the ApiModule.

Reimplemented in MediaWiki\Rest\Handler\CreationHandler, and MediaWiki\Rest\Handler\UpdateHandler.

◆ getApiMain()

MediaWiki\Rest\Handler\ActionModuleBasedHandler::getApiMain ( )

Returns: ApiMain

◆ makeMessageValue()

MediaWiki\Rest\Handler\ActionModuleBasedHandler::makeMessageValue ( IApiMessage $msg )

protected

Constructs a MessageValue from an IApiMessage.

Parameters

IApiMessage $msg

Returns: MessageValue

◆ mapActionModuleResponse()

MediaWiki\Rest\Handler\ActionModuleBasedHandler::mapActionModuleResponse	(	WebResponse	$actionModuleResponse,
		array	$actionModuleResult,
		Response	$response
	)

protected

Transfers relevant information, such as header values, from the WebResponse constructed by the action API call to a REST Response object.

Subclasses may override this to provide special case handling for header fields. For mapping the response body, override mapActionModuleResult() instead.

Subclasses overriding this method should call this method in the parent class, to preserve baseline behavior.

Parameters

WebResponse	$actionModuleResponse
array	$actionModuleResult
Response	$response

◆ mapActionModuleResult()

MediaWiki\Rest\Handler\ActionModuleBasedHandler::mapActionModuleResult ( array $data )

abstractprotected

Maps an action API result to a REST API result.

Parameters

array $data Data structure retrieved from the ApiResult returned by the ApiModule

Returns: mixed Data structure to be converted to JSON and wrapped in a REST Response. Will be processed by ResponseFactory::createFromReturnValue().

Reimplemented in MediaWiki\Rest\Handler\EditHandler.

Referenced by MediaWiki\Rest\Handler\ActionModuleBasedHandler\execute().

◆ overrideActionModule()

MediaWiki\Rest\Handler\ActionModuleBasedHandler::overrideActionModule	(	string	$name,
		string	$group,
		ApiBase	$module
	)

Overrides an action API module.

Used for testing.

Parameters

string	$name
string	$group
ApiBase	$module

Definition at line 98 of file ActionModuleBasedHandler.php.

References MediaWiki\Rest\Handler\ActionModuleBasedHandler\getApiMain().

◆ setApiMain()

MediaWiki\Rest\Handler\ActionModuleBasedHandler::setApiMain ( ApiMain $apiMain )

Set main action API entry point for testing.

Parameters

ApiMain $apiMain

Definition at line 61 of file ActionModuleBasedHandler.php.

References MediaWiki\Rest\Handler\ActionModuleBasedHandler\$apiMain.

◆ throwHttpExceptionForActionModuleError()

MediaWiki\Rest\Handler\ActionModuleBasedHandler::throwHttpExceptionForActionModuleError	(	IApiMessage	$msg,
			$statusCode = `400`
	)

protected

Throws a HttpException for a given IApiMessage that represents an error.

Never returns normally.

Subclasses may override this to provide mappings for specific error codes, typically based on $msg->getApiCode(). Subclasses overriding this method must always either throw an exception, or call this method in the parent class, which then throws an exception.

Stable to override

Parameters

IApiMessage	$msg	A message object representing an error in an action module, typically from calling getStatusValue()->getErrorsByType( 'error' ) on an ApiUsageException.
int	$statusCode	The HTTP status indicated by the original exception

Exceptions

HttpException always.
