这是我的控制器

use Symfony\Component\HttpFoundation\Request;
use Sensio\Bundle\FrameworkExtraBundle\Configuration\Route;
use Symfony\Bundle\FrameworkBundle\Controller\Controller;
use Symfony\Component\Security\Http\Authentication\AuthenticationUtils;   

class SecurityController extends Controller
{
/**
 * @Route("/login", name="login")
 */
public function loginAction(Request $request,AuthenticationUtils $authUtils)
{
    // get the login error if there is one
    $error = $authUtils->getLastAuthenticationError();

    // last username entered by the user
    $lastUsername = $authUtils->getLastUsername();

    return $this->render('blog/login.html.twig', array(
            'last_username' => $lastUsername,
            'error'         => $error,
    ));
}
}
