body: <p>I am using sessions in Laravel 5.2 . There is my Controller code:</p>
  <pre><code>if (Session::has('panier'))
  {
       $panier = Session::get('panier');  
  }
  </code></pre>
  <p>I try just to get a value from the session, and I got this error:</p>
  <pre><code>FatalErrorException in ProduitsController.php line 106: Class 'App\Http\Controllers\Session' not found
