您需要通过依赖项注入到您的侦听器类中以进行访问.

You need to inject the container via Dependency Injection into your listener class in order to acccess it.

在书籍章节中了解有关此内容的更多信息.

Read more about it in the book chapter.

your.listener:
    class: Acme\MemberBundle\EventListener\CalendarEventListener
    arguments: ["@service_container"]

尽管从性能角度来看，注入整个容器并不是***的主意，但还有其他一些原因，例如可测试性(通常应该只注入类中需要的服务，而不是注入容器)...

Though injecting the whole container is performance-wise not the best idea among with some other reasons like testability ( you should normally only inject the services you need in your class instead of the container )...

...如果您不使用UserCallable，则在注入@security.context时会得到循环引用.

...in your case if you aren't using a UserCallable you will get a circular reference when injecting @security.context.

所以最快的解决方案是注入容器并调整侦听器的构造函数:

So the quickest solution is injecting the container and adjusting your listener's constructor:

private $container;

public function __construct(ContainerInterface $container)
{
    $this->container = $container;
}



public function someOtherMethod()
{
    $user = $this->container->get('security.context')->getToken()->getUser();

    // ...
}
