Symfony-使用LexikJWTAuthenticationBundle设置TokenController

我正在使用LexikJWTAuthenticationBundle

我正在设置控制器以获取令牌：

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]);
    }
}

但我有一个错误：

未找到服务“security.password\u encoder”：即使它存在 在应用程序的容器中 “App\Controller\TokenController”是一个较小的服务定位器，用于 只知道“条令”、“form.factory”、“http_内核”， “参数包”、“请求堆栈”、“路由器”， “security.authorization\u checker”、“security.csrf.token\u manager”， “安全性。令牌存储”、“序列化程序”、“会话”和“细枝”服务。 除非您需要额外的惰性，否则请尝试使用依赖项注入 相反否则，您需要使用 “TokenController:：getSubscribedServices（）

我已经使用了依赖注入，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']

问题在哪里

您正在从

AbstractController

扩展，使用此控制器，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类构造函数

private $passwordEncoder;

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

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

或者您可以从
Symfony\Bundle\FrameworkBundle\Controller\Controller
进行扩展，以实现完整的容器访问<代码>$this->get（'security.password\u encoder'）

应该可以使用它
