中间件Slim v3中的路由模式

Question

How can I get route pattern inside middleware:

routes.php:

$app->get('/myroute/{id}', function($req, $res, $args) {
//DO STUFF HERE
})->add(new MyMiddle());

middle.php:

class MyMiddle {
    public function __invoke($req, $res, $next) {
         //DO STUFF
    }
}

In routes.php I can get {id} with $args['id'] , but how can I get it inside MyMiddle.php?

Thank you,

1. Enable the determineRouteBeforeAppMiddleware setting:

    $config = ['settings' => [ 'determineRouteBeforeAppMiddleware' => true, 'displayErrorDetails' => true, ]]; $app = new \\Slim\\App($config); 

2. You can now access the Route object from the Request, using getAttribute() and, from the route, get at the arguments:

    $app->add(function ($request, $response, $next) { $id = $request->getAttribute('route')->getArgument('id'); return $next($request, $response); });

I decided to included a Slim v2 example as that is what I was looking for when I came across this post. You can use $this->app->router()->getCurrentRoute()->getPattern() from the slim.before.dispatch callback hook to accomplish the same thing.
