using middleware in 'dispatch' event?

[samsonasik]

is it possible to use it in a 'dispatch' event, tried something like this:

$eventManager->attach('dispatch', $sm->get('AuthorizationMiddleware'));

and got the following error:

: Missing argument 2 for Application\Middleware\AuthorizationMiddleware::__invoke() in /Application/Middleware/AuthorizationMiddleware.php on line 7

While the error is argument 2, the argument 1 is an MvcEvent instance.

No, because they accept completely different arguments!

Event listeners receive an event instance, while middleware accepts a request, response, and optionally "next" callable. On top of that, the request and response from the MvcEvent are the zend-http types.

You could certainly wrap the middleware to make this happen:

use Zend\Psr7Bridge\Psr7Request;
use Zend\Psr7Bridge\Psr7Response;

$events->attach('dispatch', function ($e) use ($services) {
    $request = Psr7Request::fromZend($e->getRequest());
    $response = Psr7Response::fromZend($e->getResponse());
    $result = ($services->get('AuthorizationMiddleware'))($request, $response);
    // determine if a response should be returned, etc.
});

Thank you... I think it need to be documented ;)

Why? The MiddlewareListener details its scope clearly already, and that scope does not include arbitrary event listeners... If you'd like to contribute a cookbook recipe, however, feel free to send a pull request. 😉
