Symfony - Setup the TokenController with LexikJWTAuthenticationBundle - symfony

Question

I'm using LexikJWTAuthenticationBundle https://github.com/lexik/LexikJWTAuthenticationBundle/blob/master/Resources/doc/index.md#installation
I'm setting up my controller to get a Token:
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]);
}
}
But I have this error:
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()".
I have use Dependency injection and here is my service conf
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']
Where is the problem?

Answer 1

You are extending from AbstractController, using this controller, services that you access using $this->get() will be limited. To access the password encoder service you can inject Symfony\Component\Security\Core\Encoder\UserPasswordEncoderInterface into your controller action or through the controller class constructor.
private $passwordEncoder;
public function __construct(UserPasswordEncoderInterface $passwordEncoder)
{
$this->passwordEncoder = $passwordEncoder;
}
...
$this->passwordEncoder->isPasswordValid()
...
Or you can extend from Symfony\Bundle\FrameworkBundle\Controller\Controller for full container access. $this->get('security.password_encoder') should work with this.
