title: PSR7 on Laravel Routes: access to latest params
body: <p>Hi have the next route</p>
  
  <pre><code>Route::get('/{param1}',
          'Http\Controllers\SomeController@getCollection');
  Route::get('/{param_for_middleware}/{param1}',
          'Http\Controllers\SomeController@getCollection');
  </code></pre>
  
  <p>And, on my controller, I have</p>
  
  <pre><code>// PSR7 code
  use Illuminate\Routing\Controller;
  use Psr\Http\Message\ServerRequestInterface;
  
  class SomeController extends Controller
      public function getCollection(ServerRequestInterface $request)
      {
          // here, I need access to param1
          dd($request);
      }
  }
  </code></pre>
  
  <p>With Original Laravel Router We can get value with <code>$this-&gt;route()-&gt;parameters()['param1]</code>. But, when we use PSR7 on Laravel?</p>
