Hello, I need to edit the $request object before slim v4 router call the route. This is an example:

An example of my request: [https://website.com/param/myroute](https://website.com/param/myroute)

Slim route that trigger that request:  
$app-\>get(’/myroute’, function (Request $request, Response $response, $args) {  
…  
});

Another example: [https://website.com/param/](https://website.com/param/)

Slim route that trigger that request:  
$app-\>get(’/’, function (Request $request, Response $response, $args) {  
…  
});

I need to remove param from the $request object before slim trigger the routes.

(don’t suggest to use $app-\>setBasePath because param is a variable param not always defined).

Thanks for suggestions.

Have you tried using a route group with a placeholder for the first param?

Hello, I have solved with this trick (this is a middleware):

use Slim\Psr7\Request;  
use Psr\Http\Server\RequestHandlerInterface as RequestHandler;  
use Slim\Psr7\Response;

class Myclass  
{  
public function \_\_invoke(Request $request, RequestHandler $handler): Response  
{  
$request = $request-\>withUri($request-\>getUri()-\>withPath(’/here the path with basepath without param/’));  
$response = $handler-\>handle($request);  
return $response;  
}  
}
