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,

Answer 1

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);
   });
