In Symfony, you can log out a user by invalidating their session and removing their authentication token. Here's one way you can do it:
- Import the necessary classes at the top of your controller or service class:
1 2 3 |
use SymfonyComponentSecurityCoreAuthenticationTokenStorageTokenStorageInterface; use SymfonyComponentHttpFoundationRequestStack; use SymfonyComponentHttpFoundationSessionSessionInterface; |
- Inject the TokenStorageInterface, RequestStack, and SessionInterface services into your class constructor or method:
1 2 3 4 5 6 |
public function __construct(TokenStorageInterface $tokenStorage, RequestStack $requestStack, SessionInterface $session) { $this->tokenStorage = $tokenStorage; $this->requestStack = $requestStack; $this->session = $session; } |
- Create a method to log out the user:
1 2 3 4 5 6 7 8 9 10 11 12 13 14 |
public function logout() { // Get the current request $request = $this->requestStack->getCurrentRequest(); // Invalidate the session $this->session->invalidate(); // Remove the authentication token $this->tokenStorage->setToken(null); // Redirect the user to the login page return $this->redirectToRoute('login'); } |
- In your route configuration, specify this method as the handler for the logout route:
1 2 3 4 |
logout: path: /logout methods: [GET] controller: AppControllerSecurityController::logout |
You can then trigger the logout process by directing the user to the logout route (e.g., by providing a link to it).
Keep in mind that this is just one way to implement a logout feature in Symfony. There are other approaches you can take, depending on your specific requirements.
