在内核事件中访问当前用户 [Symfony 4]答案

【问题标题】：Access current user in the kernel events [Symfony 4]在内核事件中访问当前用户 [Symfony 4]

【问题描述】：

我不想保存我的用户的导航。

我正在尝试将其从'kernel.request' 事件中保存，但我无法获取当前用户...

在我的事件监听器中：

KernelEvents::REQUEST => ['logNavigation0']

还有功能：

public function logNavigation0(GetResponseEvent $event): void
    {
        dump(
            $event->getRequest()->getUser()
        );
    }

我的用户已连接，但getUser() 回复我null

如何找回我的用户？还有其他方法吗？

谢谢！

我的代码：

class PlayerAction implements EventSubscriberInterface, LogoutHandlerInterface
{
    private $mailer;
    private $requestStack;
    private $entityManager;
    private $tokenStorage;
    private $sender;
    protected $serializer;

    public function __construct(\Swift_Mailer $mailer, RequestStack $requestStack, EntityManagerInterface $entityManager, TokenStorageInterface $tokenStorage, $sender)
    {
        $this->mailer = $mailer;
        $this->requestStack = $requestStack;
        $this->entityManager = $entityManager;
        $this->tokenStorage = $tokenStorage;
        $this->sender = $sender;

        $this->serializer = new Serializer([new ObjectNormalizer()], [new JsonEncoder()]);
    }

    public static function getSubscribedEvents(): array
    {
        return [
            // le nom de l'event et le nom de la fonction qui sera déclenché
            Events::PLAYER_REGISTERED => ['logSuccessRegistration'],
            Events::PLAYER_UPDATED => ['logSuccessRegistration'],
            Events::PLAYER_PLAYING => ['logPlay'],
            Events::PLAYER_WINNING => ['logWin'],

            AuthenticationEvents::AUTHENTICATION_SUCCESS => ['logSuccessLogin'],
            AuthenticationEvents::AUTHENTICATION_FAILURE => ['logFailureLogin'],

            KernelEvents::REQUEST => ['logNavigation0'],
            KernelEvents::CONTROLLER_ARGUMENTS => ['logNavigation1'],
        ];
    }
    [...]
    public function logNavigation0(GetResponseEvent $event): void
    {
        dump(
            $event->getRequest()->getUser() //Return null,
        );
    }

public function logNavigation1(FilterControllerArgumentsEvent $event): void
    {
        dump(
            $event,
            $event->getRequest()->getUser(), //Return null,
            ($event->getArguments()),
            $this->tokenStorage->getToken() //Return null,
        );
    }
}

【问题讨论】：

你为什么不注入TokenStorageInterface？
Symfony 2.8: Cannot get current user in Service (FosUserBundle)的可能重复
尝试通过 Symfony\Component\Security\Core\Authentication\Token\Storage\TokenStorageInterface 作为依赖注入，然后调用类似这样的东西 $user = $tokenStorage->getToken() ？ $tokenStorage->getToken()->getUser() : null;
你在开发环境吗？如果是，工具栏是否显示您已作为特定用户连接？
我尝试注入 TokenStorageInterface，结果是一样的……是的，我的调试栏显示了我的用户。

我收到了回复！

开发环境太快了，我觉得……

public function logNavigation(GetResponseEvent $event): void
{
    if(!empty($this->tokenStorage->getToken())) // In debug mode, it's null
    {
        /** @var Player $player */
        $player = $this->tokenStorage->getToken()->getUser();

        if($player instanceof Player)
        {
            $playerHystory = new PlayerHistory();
            $playerHystory
                ->setLabel('NAVIGATION')
                ->setDetails([
                    'path' => $event->getRequest()->getPathInfo(),
                    'method' => $event->getRequest()->getMethod()
                ])
                ->setPlayer($player)
                ->setIp($this->requestStack->getCurrentRequest()->getClientIp())
            ;

            $this->entityManager->persist($playerHystory);
            $this->entityManager->flush();
        }
    }
}
