Detailed Description

A REST module represents a collection of endpoints.

The module object is responsible for generating a response for a given request. This is typically done by routing requests to the appropriate request handler.

Member Function Documentation

◆ execute()

MediaWiki\Rest\Module\Module::execute	(	string	$path,
		RequestInterface	$request )

Find the handler for a request and execute it.

Definition at line 262 of file Module.php.

◆ executeHandler()

MediaWiki\Rest\Module\Module::executeHandler ( Handler $handler )

protected

Execute a fully-constructed handler.

Exceptions

HttpException

Definition at line 365 of file Module.php.

◆ findHandlerMatch()

MediaWiki\Rest\Module\Module::findHandlerMatch	(	string	$path,
		string	$requestMethod )

abstractprotected

Determines which handler to use for the given path and returns an array describing the handler and initialization context.

Parameters

string	$path
string	$requestMethod

Returns

array<string,mixed>

bool "found": Whether a match was found. If true, the handler or spec field must be set.
Handler handler: the Handler object to use. Either "handler" or "spec" must be given.
array "spec":" an object spec for use with ObjectFactory - array "config": the route config, to be passed to Handler::initContext() - string "path": the path the handler is responsible for, including placeholders for path parameters. - string[] "params": path parameters, to be passed the Request::setPathPrams() - string[] "methods": supported methods, if the path is known but the method did not match. Only meaningful if "found" is false. To be used in the Allow header of a 405 response and included in CORS pre-flight.

Reimplemented in MediaWiki\Rest\Module\MatcherBasedModule.

◆ getAllowedMethods()

MediaWiki\Rest\Module\Module::getAllowedMethods ( string $relPath )

abstract

Get the allowed methods for a path.

Useful to check for 405 wrong method and for generating OpenAPI specs.

Parameters

string $relPath A concrete request path.

Returns: string[] A list of allowed HTTP request methods for the path. If the path is not supported, the list will be empty.

Reimplemented in MediaWiki\Rest\Module\MatcherBasedModule.

◆ getCacheData()

MediaWiki\Rest\Module\Module::getCacheData ( )

abstract

Return data that can later be used to initialize a new instance of this module in a fast and efficient way.

See also: initFromCacheData()

Returns: array An associative array suitable to be processed by initFromCacheData. Implementations are free to choose the format.

Reimplemented in MediaWiki\Rest\Module\MatcherBasedModule.

◆ getDefinedPaths()

MediaWiki\Rest\Module\Module::getDefinedPaths ( )

abstract

Access: internal: for testing

Returns: array[] An associative array, mapping path patterns to a list of request methods supported for the path.

Reimplemented in MediaWiki\Rest\Module\ExtraRoutesModule, and MediaWiki\Rest\Module\SpecBasedModule.

◆ getHandlerForPath()

MediaWiki\Rest\Module\Module::getHandlerForPath	(	string	$path,
		RequestInterface	$request,
		bool	$initForExecute = false )

Create a Handler for the given path, taking into account the request method.

If $prepExecution is true, the handler's prepareForExecute() method will be called, which will call postInitSetup(). The $request object will be updated with any path parameters and parsed body data.

Stability: unstable

Parameters

string	$path
RequestInterface	$request	The request to handle. If $forExecution is true, this will be updated with the path parameters and parsed body data as appropriate.
bool	$initForExecute	Whether the handler and the request should be prepared for execution. Callers that only need the Handler object for access to meta-data should set this to false.

Returns: Handler

Exceptions

HttpException If no handler was found

Definition at line 135 of file Module.php.

◆ getOpenApiInfo()

MediaWiki\Rest\Module\Module::getOpenApiInfo ( )

Return an array with data to be included in an OpenAPI "info" object describing this module.

See also: https://spec.openapis.org/oas/v3.0.0#info-object

Returns: array

Reimplemented in MediaWiki\Rest\Module\SpecBasedModule.

Definition at line 462 of file Module.php.

◆ getPathPrefix()

MediaWiki\Rest\Module\Module::getPathPrefix ( )

Definition at line 80 of file Module.php.

◆ getRouter()

MediaWiki\Rest\Module\Module::getRouter ( )

Definition at line 189 of file Module.php.

◆ initFromCacheData()

MediaWiki\Rest\Module\Module::initFromCacheData ( array $cacheData )

abstract

Initialize from the given cache data if possible.

This allows fast initialization based on data that was cached during a previous invocation of the module.

Implementations are responsible for verifying that the cache data matches the information provided to the constructor, to protect against a situation where configuration was updated in a way that affects the operation of the module.

Parameters

array $cacheData Data generated by getCacheData(), implementations are free to choose the format.

Returns: bool true if the cache data could be used, false if it was discarded.

See also: getCacheData()

◆ instantiateHandlerObject()

MediaWiki\Rest\Module\Module::instantiateHandlerObject ( array $spec )

protected

Creates a handler from the given spec, but does not initialize it.

Definition at line 351 of file Module.php.

◆ loadJsonFile()

static MediaWiki\Rest\Module\Module::loadJsonFile ( string $fileName )

static

Loads a module specification from a file.

This method does not know or care about the structure of the file other than that it must be JSON and contain a list or map (that is, a JSON array or object).

Parameters

string $fileName

Access: internal

Returns: array An associative or indexed array describing the module

Exceptions

ModuleConfigurationException

Definition at line 436 of file Module.php.

◆ setCors()

MediaWiki\Rest\Module\Module::setCors ( CorsUtils $cors )

Parameters

CorsUtils $cors

Returns: self

Definition at line 403 of file Module.php.

◆ setStats()

MediaWiki\Rest\Module\Module::setStats ( StatsFactory $stats )

Access: internal: for use by Router

Parameters

StatsFactory $stats

Returns: self

Definition at line 416 of file Module.php.

◆ throwNoMatch()

MediaWiki\Rest\Module\Module::throwNoMatch	(	string	$path,
		string	$method,
		array	$allowed )

protected

Implementations of getHandlerForPath() should call this method when they cannot handle the requested path.

Parameters

string	$path	The requested path
string	$method	The HTTP method of the current request
string[]	$allowed	The allowed HTTP methods allowed by the path

Returns: never

Exceptions

HttpException
