Symfony 4：事件侦听器无法自动装配用户界面

Question

当我将 UserInterface 添加到我的事件侦听器时，出现以下错误：

Cannot autowire service "App\EventListener\ControllerListener": argument "$user" of method "__construct()" references interface "Symfony\Component\Security\Core\User\UserInterface" but no such service exists. It cannot be auto-registered because it is from a different root namespace.

我不知道发生了什么，其他服务工作正常。你能找到代码并告诉我我做错了什么吗？

~src/EventListener/ControllerListener.php

<?php
namespace App\EventListener;

use App\Entity\User;
use App\Entity\DailyWin;
use App\Controller\DailyWinController;
use Psr\Log\LoggerInterface;
use Symfony\Component\Security\Core\User\UserInterface;
use Symfony\Bundle\FrameworkBundle\Controller\Controller;
use Symfony\Component\HttpKernel\Event\FilterControllerEvent;
use Symfony\Component\Security\Core\Authorization\AuthorizationCheckerInterface;

class ControllerListener extends Controller implements DailyWinController
{
    private $authChecker, $user, $logger;

    public function __construct(UserInterface $user, AuthorizationCheckerInterface $authChecker, LoggerInterface $logger) {
        $this->user = $user;
        $this->authChecker = $authChecker;
        $this->logger = $logger;
    }

    public function onKernelController(FilterControllerEvent $event) {
        if ($this->authChecker->isGranted('IS_AUTHENTICATED_FULLY') === false) return;

        $this->logger->warning('Inicjowanie...');

        $em = $this->getDoctrine()->getManager();
        $DWrep = $em->getRepository(DailyWin::class);

        $userId = $this->user->getId();
        $userDailyWin = $DWrep->findOneBy(['userId' => $userId]);
        $this->logger->warning(print_r($userDailyWin));

        if (empty($userDailyWin)) {
            $currentDate = new \DateTime(date('Y-m-d', time()));
            $userDailyWin = new DailyWin();
            $userDailyWin->setUserId($userId);
            $userDailyWin->setMultiplier(0);
            $userDailyWin->setClaimed(0);
            $userDailyWin->setStreak(0);
            $userDailyWin->setLastLogin($currentDate);

            $em->persist($userDailyWin);
            $em->flush();
        }
    }
}

谢谢。

Answer 1

用户不是 symfony 服务，它不会被自动装配。

试试这个界面：

Symfony\Component\Security\Core\Authentication\Token\Storage\TokenStorageInterface

然后你做：

$user=$tokenStorage->getToken()->getUser();

Answer 2

从 Symfony 3.2 开始，引入了一个新的用户解析器。它似乎不允许通过构造函数注入（我也试图使它起作用），但你应该注入你的方法。

public function onKernelController(UserInterface $user , FilterControllerEvent $event) {

根据documentation

Answer 3

聚会迟到了，但在控制器中你也可以只使用：

$user = $this->getUser();

从 Symfony 3.2 开始，参见 here
