symfony2註銷

Question

我的問題是捕獲用戶註銷。什麼我的代碼是：

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')); 
} 

問題是，當你正在運行的註銷功能無法訪問用戶令牌TokenInterface？

Answer 1

要獲取令牌，必須注入安全上下文。

1.創建類註銷監聽器，像這樣：

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.然後在service.yml，加入這一行：

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

就是這樣，可能它有助於。

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

security.yml

secured_area: 

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

看看這裏都可以覆蓋束的任何控制器：
