symfony2 logout

Question

My problem is capture user logout. the code what i have is:

public  function onAuthenticationFailure(Request $request, AuthenticationException $exception){

    return new Response($this->translator->trans($exception->getMessage()));
}

public function logout(Request $request, Response $response, TokenInterface $token)
{
    $empleado = $token->getUser();
    $log = new Log();
    $log->setFechalog(new \DateTime('now'));
    $log->setTipo("Out");
    $log->setEntidad("");
    $log->setEmpleado($empleado);
    $this->em->persist($log);
    $this->em->flush();
}

public function onLogoutSuccess(Request $request) {
    return new RedirectResponse($this->router->generate('login'));
}

The problem is I can not access the user token TokenInterface when you are running the logout function?

the soluction problem is the service security context thanks. — paradita

Is $token->getUser() returning null? Or the $token is null? — Kosta

To get token, you must inject with security context.

1. Create class Logout listener, something like this:

namespace Yourproject\Yourbundle\Services;
...
use Symfony\Component\Security\Http\Logout\LogoutSuccessHandlerInterface;
use Symfony\Component\Security\Core\SecurityContext;

class LogoutListener implements LogoutSuccessHandlerInterface {

  private $security;  

  public function __construct(SecurityContext $security) {
    $this->security = $security;
  }

  public function onLogoutSuccess(Request $request) {
     $user = $this->security->getToken()->getUser();

     //add code to handle $user here
     //...

     $response =  RedirectResponse($this->router->generate('login'));

    return $response;
  }
}

2. And then in service.yml, add this line:

....
logout_listener:
   class:  Yourproject\Yourbundle\Services\LogoutListener
   arguments:  [@security.context]

That's it, may it helps.

This won't work, for logout_listener service you have no defined event. So the listener won't be fired at all.

@artworkadシ, i have registered this event on service.yml, so it will be fired when user do logout. i have used this on several project symphony, and there is no problem.

In my opinion it is necessary adding ALSO the lines in the answer on Jul 24 '14 at 15:22. It worked for me at symfony 2.5.

In Symfony 3 you have to use ['@security.authorization_checker'] instead of security.context

See http://symfony.com/doc/current/reference/configuration/security.html

security.yml

secured_area:

    logout:
        path:   /logout
        **success_handler: logout_listener**

Take a look here were you can overwrite any controller of the bundle:
