How to Manually Validate a CSRF Token in a Controller
Sometimes, you want to use CSRF protection in an action where you do not want to use the Symfony Form component. If, for example, you are implementing a DELETE action, you can use the isCsrfTokenValid() method to check the validity of a CSRF token:
1 2 3 4 5 6
public function deleteAction()
{
if ($this->isCsrfTokenValid('token_id', $submittedToken)) {
// ... do something, like deleting an object
}
}2.6
The isCsrfTokenValid() shortcut method was introduced in Symfony 2.6.
It is equivalent to executing the following code:
1 2 3 4
use Symfony\Component\Security\Csrf\CsrfToken;
$this->get('security.csrf.token_manager')
->isTokenValid(new CsrfToken('token_id', 'TOKEN'));
