以编程方式注销当前用户 [英] Programmatically logout current user

问题描述

我正在尝试以编程方式从侦听器内部注销当前用户.我在此处阅读了

I am trying to programmatically logout the current user from inside a listener. I read here that

$this->get('security.context')->setToken(null);
$this->get('request')->getSession()->invalidate();

可以解决问题，但是我不能调用 $ this-> container-> get('security.context')-> getToken()-> getUser(); 因为令牌现在是 NULL .

does the trick but then I can't call $this->container->get('security.context')->getToken()->getUser(); anymore as the token is now NULL.

如何注销用户，但仍然让应用程序正常运行?我在控制器函数中调用了getUser()，因此我应该将令牌重新设置为与未经身份验证的用户相对应的名称.我该怎么办?

How can I log out the user but still let the application run normally? I have calls to getUser() in my controller functions so I should set back the token to something corresponding to an non authenticated user. How can I do this?

此外，如果有一种方法可以通过编程方式开始一个新会话并设置一条Flash消息来通知用户他已经注销，那真是太棒了.

Also, if there is a way to programmatically start a new session and set a flash message to inform the user he has been logged out, it would be awesome.

推荐答案

尝试

$anonToken = new AnonymousToken('theTokensKey', 'anon.', array());
$this->get('security.context')->setToken($anonToken);

第一个参数是令牌的密钥(即'50cdf89882454')

first parameter is the token's key (i.e. '50cdf89882454')
