Question

根据FOSuserBndle中的角色，我在重定向路径中遇到问题。问题在于：

FatalErrorException：错误：在a上调用成员函数generate（） ......中的非对象

这是事件监听器

namespace Register\UserBundle\EventListener;

似乎路由器没有注入你的监听器/服务。

听众课程：

...
use Symfony\Component\Routing\Router;

class LoginListener
{
    protected $container;
    protected $em;
    protected $router;

    public function __construct(ContainerInterface $container, EntityManager $em, Router $router)
    {
        $this->container = $container;
        $this->em = $em;
        $this->router = $router;
    }
    ...
}

服务声明：

my_bundle.my_listener:
    class: %my_bundle.my_listener.class%
    arguments: [ @service_container, @doctrine.orm.entity_manager, @router ]

如何解决EventListener中的错误？
