用户无法在Symfony2中正确注销

Question

I'm trying to logout an user (session) when the Logout link is clicked. It seems to work when I pressed the Logout, but if I change the path, the user still alive and I don't know why.

Here's my Controller:

 /**
   * @Route("/logout", name="logout")
   */
public function logoutAction(Request $request)
{
    $helper = $this->get('security.authentication_utils');
    $this->container->get('security.token_storage')->setToken(null);
    $this->get('session')->set('id', null);
    $request->getSession()->invalidate();
    $this->get('security.token_storage')->setToken(null);


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

Here's my security.yml:

security:
    # ...
    main:
        anonymous: ~
        guard:
            authenticators:
                - app.form_login_authenticator
        logout:
            path: logout
            target: logout
            invalidate_session: true

Here's the routing.yml:

app:
    resource: '@AppBundle/Controller/'
logout:
    path: /logout

Remove the logoutAction and check if it works. This action is provided by Symfony itself. You should only set logout path in security.yml what you did.
