Question

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]);
    }
}

但是我有这个错误：

Service "security.password_encoder" not found: even though it exists in the app's container, the container inside "App\Controller\TokenController" is a smaller service locator that only knows about the "doctrine", "form.factory", "http_kernel", "parameter_bag", "request_stack", "router", "security.authorization_checker", "security.csrf.token_manager", "security.token_storage", "serializer", "session" and "twig" services. Unless you need extra laziness, try using dependency injection instead. Otherwise, you need to declare it using "TokenController::getSubscribedServices()".

我使用了依赖注入，这是我的服务配置文件

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']

问题出在哪里？

Answer 1

您正在使用此控制器从 AbstractController 扩展，您使用 $this->get() 访问的服务将受到限制。要访问密码编码器服务，您可以将 Symfony\Component\Security\Core\Encoder\UserPasswordEncoderInterface 注入控制器操作或通过控制器 class 构造函数。

private $passwordEncoder;

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

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

或者您可以从 Symfony\Bundle\FrameworkBundle\Controller\Controller 扩展以获得完整的容器访问权限。 $this->get('security.password_encoder') 应该适用于此。
