How to edit $request-url in middleware in Laravel 5.8 before it hits route API - url

Question

I'm developing an API. I want to edit the incoming $request->url so it hits different routes based on the authorization. It should work for any kind of request (POST, GET , DELETE etc...).
By now I 've come this far. The middleware get hit, but $request->server->set('REQUEST_URI','http://...'); doesn 't have any effect. The incoming $request url stays at it is. This is the simplified middleware code of the class RedirectToUrl:
<?php
namespace App\Http\Middleware;
use Closure;
use Auth;
use Illuminate\Http\Request;
class RedirectToUrl
{
/**
* Handle an incoming request.
*
* #param \Illuminate\Http\Request $request
* #param \Closure $next
* #return mixed
*/
public function handle(Request $request, Closure $next)
{
if($request->user()->role()->first()->role === "admin"){
$request->server->set('REQUEST_URI','http://rest-api-with-session-httponly:8888/api/admin');
}elseif($request->user()->role()->first()->role === "basic"){
$request->server->set('REQUEST_URI','http://rest-api-with-session-httponly:8888/api/basic');
}else{
$request->server->set('REQUEST_URI','http://rest-api-with-session-httponly:8888/api/basic');
}
return $next($request);
}
}
I`ve put the middleware RedirectToUrl::class at the end of the middleware priority:
protected $middlewarePriority = [
\App\Http\Middleware\AddAuthHeader::class,
\Illuminate\Auth\Middleware\Authenticate::class,
\Illuminate\Session\Middleware\StartSession::class,
\Illuminate\View\Middleware\ShareErrorsFromSession::class,
\App\Http\Middleware\Authenticate::class,
\Illuminate\Session\Middleware\AuthenticateSession::class,
\Illuminate\Routing\Middleware\SubstituteBindings::class,
\Illuminate\Auth\Middleware\Authorize::class,
\App\Http\Middleware\CheckRole::class,
\App\Http\Middleware\RedirectToUrl::class,
];
Any hint appreciated.
Thx!
