Symfony：如何从数据库中刷新经过身份验证的用户？

Question

Say for example I grant a new role to the currently authenticated user in a controller, like so:

$em = $this->getDoctrine()->getManager();
$loggedInUser = $this->get('security.context')->getToken()->getUser();
$loggedInUser->addRole('ROLE_XYZ');

$em->persist($loggedInUser);
$em->flush();

On the next page load, when I grab the authenticated user again:

$loggedInUser = $this->get('security.context')->getToken()->getUser();

They are not granted the role. I am guessing this is because the user is stored in the session and needs to be refreshed.

How do I do this?

I am using FOSUserBundle if that makes a difference.

EDIT : This question was originally asked in the context of Symfony version 2.3 but there are answers for more recent versions below as well.

Answer 1

Try this:

$em = $this->getDoctrine()->getManager();
$loggedInUser = $this->get('security.context')->getToken()->getUser();
$loggedInUser->addRole('ROLE_XYZ');

$em->persist($loggedInUser);
$em->flush();

$token = new \Symfony\Component\Security\Core\Authentication\Token\UsernamePasswordToken(
  $loggedInUser,
  null,
  'main',
  $loggedInUser->getRoles()
);

$this->container->get('security.context')->setToken($token);

Answer 2

There's no need for the token reset in the previous answer. Just, in your security config file (security.yml, etc...), add this:

security:
    always_authenticate_before_granting: true

Answer 3

While an answer is accepted, Symfony actually has a native way to refresh the User object. Credit goes out to Joeri Timmermans for this article .

Steps for refreshing the User object:

1. Make your User entity implement the interface

Symfony\\Component\\Security\\Core\\User\\EquatableInterface

2. Implement the abstract function isEqualTo:

 public function isEqualTo(UserInterface $user) { if ($user instanceof User) { // Check that the roles are the same, in any order $isEqual = count($this->getRoles()) == count($user->getRoles()); if ($isEqual) { foreach($this->getRoles() as $role) { $isEqual = $isEqual && in_array($role, $user->getRoles()); } } return $isEqual; } return false; }

The code above refreshes the User object if any new roles are added. The same principle also holds true for other fields you compare.

Answer 4

$user = $this->getUser();
$userManager = $this->get('fos_user.user_manager');
$user->addRole('ROLE_TEACHER');
$userManager->updateUser($user);
$newtoken = new \Symfony\Component\Security\Core\Authentication\Token\UsernamePasswordToken($user,null,'main', $user->getRoles());
$token = $this->get('security.token_storage')->setToken($newtoken);

Answer 5

In Symfony 4

public function somename(ObjectManager $om, TokenStorageInterface $ts)
    {
        $user = $this->getUser();
        if ($user) {
            $user->setRoles(['ROLE_VIP']); //change/update role
            // persist if need
            $om->flush();
            $ts->setToken(
                new PostAuthenticationGuardToken($user, 'main', $user->getRoles())
            );
            //...
        } else {
            //...
        }
    }
