在構造函數中訪問路由參數 - Laravel 5.1

Question

我從以前的Laravel 4.x下面有這段代碼。我怎樣才能將它轉換成Laravel 5.1？我想知道如何在構造函數（或中間件）中訪問路由參數，如果我將它轉換爲Laravel 5.1

謝謝！

public function __construct() 
{ 
    $this->beforeFilter(function($route, $request) 
    { 
     $this->user  = Auth::user(); 
     $this->project = $this->user->getProject($route->parameter('projects')); 
     $this->group = $this->project->groups()->find($route->parameter('groups')); 
    }); 
}
