php - Symfony:如何从数据库中刷新经过身份验证的用户？

Question

例如，我在 Controller 中向当前经过身份验证的用户授予了一个新角色，如下所示:

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

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

在下一个页面加载时，当我再次获取经过身份验证的用户时:

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

他们未被授予该角色。我猜这是因为用户存储在 session 中，需要刷新。

我该怎么做？

如果有不同，我正在使用 FOSUserBundle。

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

试试这个:

$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);
