Symfony - 使用 LexikJWTAuthenticationBundle 设置 TokenController

我正在使用 LexikJWTAuthenticationBundle https://github.com/lexik/LexikJWTAuthenticationBundle/blob/master/Resources/doc/index.md#installation

我正在设置我的控制器以获取令牌：

class TokenController extends AbstractController
{
    /**
     * @Route("/api/token", name="token", methods={"POST"})
     * @param Request $request
     * @param JWTEncoderInterface $JWTEncoder
     * @return JsonResponse
     * @throws \Lexik\Bundle\JWTAuthenticationBundle\Exception\JWTEncodeFailureException
     */
    public function token(Request $request, JWTEncoderInterface $JWTEncoder)
    {
        $user = $this->getDoctrine()->getRepository(User::class)->findOneBy([
            'email' => $request->getUser(),
        ]);

        if (!$user) {
            throw $this->createNotFoundException('User Not Found');
        }

        $isValid = $this->get('security.password_encoder')
            ->isPasswordValid($user, $request->getPassword());
        if (!$isValid) {
            throw new BadCredentialsException();
        }
        $token = $JWTEncoder->encode([
                'email' => $user->getEmail(),
                'exp' => time() + 3600 // 1 hour expiration
            ]);

        return new JsonResponse(['token' => $token]);
    }
}

但我有这个错误：

找不到服务“security.password_encoder”：即使它存在于应用程序的容器中，“App\Controller\TokenController”中的容器是一个较小的服务定位器，只知道“doctrine”、“form.factory”、“http_kernel” ", "parameter_bag", "request_stack", "router", "security.authorization_checker", "security.csrf.token_manager", "security.token_storage", "serializer", "session" 和 "twig" 服务。除非您需要额外的懒惰，否则请尝试使用依赖注入。否则，您需要使用“TokenController::getSubscribedServices()”来声明它。

我使用了依赖注入，这是我的服务配置

services:
    # default configuration for services in *this* file
    _defaults:
        autowire: true      # Automatically injects dependencies in your services.
        autoconfigure: true # Automatically registers your services as commands, event subscribers, etc.
        public: false       # Allows optimizing the container by removing unused services; this also means
                            # fetching services directly from the container via $container->get() won't work.
                            # The best practice is to be explicit about your dependencies anyway.

    # makes classes in src/ available to be used as services
    # this creates a service per class whose id is the fully-qualified class name
    App\:
        resource: '../src/*'
        exclude: '../src/{DependencyInjection,Entity,Migrations,Tests,Kernel.php}'

    # controllers are imported separately to make sure services can be injected
    # as action arguments even if you don't extend any base controller class
    App\Controller\:
        resource: '../src/Controller'
        tags: ['controller.service_arguments']

问题出在哪儿？

您AbstractController使用此控制器从扩展，您使用的服务$this->get()将受到限制。要访问密码编码器服务，您可以注入Symfony\Component\Security\Core\Encoder\UserPasswordEncoderInterface控制器操作或通过控制器类构造函数。

private $passwordEncoder;

public function __construct(UserPasswordEncoderInterface $passwordEncoder)
{
  $this->passwordEncoder = $passwordEncoder;
}
...

$this->passwordEncoder->isPasswordValid()
...

或者，您可以从扩展Symfony\Bundle\FrameworkBundle\Controller\Controller获取完整的容器访问权限。$this->get('security.password_encoder')应该与此合作。
