推荐答案

从 Symfony 2.6 开始，您可以从安全令牌存储中检索用户，例如您的控制器：

As of Symfony 2.6 you can retrieve a user from the security token storage, for example in your controller:

$user = $this->get('security.token_storage')->getToken()->getUser();

在Symfony 2.6 之前，令牌可以从安全上下文服务中访问：

Before Symfony 2.6, the token was accessible from the security context service instead:

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

安全上下文服务已被弃用，将在Symfony 3.0中删除。

如果扩展基本控制器，还可以使用快捷方式：

If you extend the base controller, you can also use a shortcut method:

$user = $this->getUser();

然后你可以得到你想要的东西：

Then you can get whatever your want:

$userId = $user->getId();

当然，您的用户类需要实现getId（）方法。

Of course your user class needs to implement the getId() method.

所有这些都在文档中描述： http ：//symfony.com/doc/current/book/security.html#retrieving-the-user-object

All of this is described in the documentation: http://symfony.com/doc/current/book/security.html#retrieving-the-user-object
