README
The package is a flexible PSR-15 middleware dispatcher for PSR-7 request message that help to create middlewares and dispatch.
Installation
Install via composer
composer require slince/middleware
Quick example
$dispatcher = new Slince\Middleware\Dispatcher([$middleware1, $middleware2]); $response = $dispatcher->process(Zend\Diactoros\ServerRequestFactory::fromGlobals()); var_dump($response instanceof Psr\Http\Message\ResponseInterface);
Usage
Add middleware
Add PSR-15 middlewares to the queue
use Psr\Http\Message\ServerRequestInterface; use Interop\Http\Server\MiddlewareInterface; use Interop\Http\Server\RequestHandlerInterface; use Zend\Diactoros\Response; class MyMiddleware implements MiddlewareInteface { public function process(ServerRequestInterface $request, RequestHandlerInterface $next) { $response = new Response(); $response->getBody()->write('hello world'); return $response; } } $dispatcher = new Slince\Middleware\Dispatcher([ new MyMiddleware() ]);
Or add a callable function directly
$dispatcher->push(function(ServerRequestInterface $request, RequestHandlerInterface $next){ return $delegate->process($request); });
Dispatch
try { $response = $dispatcher->process(Zend\Diactoros\ServerRequestFactory::fromGlobals()); } catch (Slince\Middleware\Exception\MissingResponseException $exception) { //... }
A MissingResponseException
will be thrown if the middleware did not return a invalid response or the queue was exhausted
