PHP Class Phly\Conduit\MiddlewarePipe

This class implements a pipe-line of middleware, which can be attached using the pipe() method, and is itself middleware. The request and response objects are decorated using the Phly\Conduit\Http variants in this package, ensuring that the request may store arbitrary properties, and the response exposes the convenience write(), end(), and isComplete() methods. It creates an instance of Next internally, invoking it with the provided request and response instances; if no $out argument is provided, it will create a FinalHandler instance and pass that to Next as well. Inspired by Sencha Connect.

Method Details

__construct() public méthode

Initializes the queue.

public __construct ( )

__invoke() public méthode

Takes the pipeline, creates a Next handler, and delegates to the Next handler. If $out is a callable, it is used as the "final handler" when $next has exhausted the pipeline; otherwise, a FinalHandler instance is created and passed to $next during initialization.

public __invoke ( Psr\Http\Message\ServerRequestInterface $request, Psr\Http\Message\ResponseInterface $response, callable $out = null ) : Psr\Http\Message\ResponseInterface
$request	Psr\Http\Message\ServerRequestInterface
$response	Psr\Http\Message\ResponseInterface
$out	callable
Résultat	Psr\Http\Message\ResponseInterface

pipe() public méthode

Each middleware can be associated with a particular path; if that path is matched when that middleware is invoked, it will be processed; otherwise it is skipped. No path means it should be executed every request cycle. A handler CAN implement MiddlewareInterface, but MUST be callable. Handlers with arity >= 4 or those implementing ErrorMiddlewareInterface are considered error handlers, and will be executed when a handler calls $next with an error or raises an exception.
