php - 使用新的 Symfony 5 Authenticator 注册后如何手动验证用户？

Question

Symfony 5 已将其保护身份验证方法更改为新的基于 Passport 的方法，使用新的安全配置:enable_authenticator_manager: true ;
我想知道在 ORM (Doctrine) 持久化用户后，如何在我的 Controller 中的注册表单方法中对用户进行身份验证；
我已成功使用登录表单对用户进行身份验证，但我仍然不知道如何手动执行此操作。

根据 Cerad的评论，这里是完整的答案。
以下只是与问答相关的代码部分。这些不是完整的文件。
此外，这仅适用于 Symfony ^5.2，即 不是 使用guard来验证用户。

/* config/packages/security.yaml */

security:
    enable_authenticator_manager: true
    firewalls:
        main:
            custom_authenticators:
                - App\Security\SecurityAuthenticator

/* src/Security/SecurityAuthenticator.php */

use Symfony\Component\Security\Http\Authenticator\AbstractLoginFormAuthenticator;

/* automatically generated with the make:auth command,
     the important part is to undestand that this is not a Guard implement 
     for the Authenticator class */
class SecurityAuthenticator extends AbstractLoginFormAuthenticator
{
  
}

/* src/Controller/RegistrationController.php */

use App\Entity\User;
use App\Form\RegistrationFormType;
use App\Security\SecurityAuthenticator;

use Symfony\Bundle\FrameworkBundle\Controller\AbstractController;
use Symfony\Component\HttpFoundation\Request;
use Symfony\Component\HttpFoundation\Response;
use Symfony\Component\Routing\Annotation\Route;
use Symfony\Component\Security\Core\Encoder\UserPasswordEncoderInterface;
use Symfony\Component\Security\Http\Authentication\UserAuthenticatorInterface;

class RegistrationController extends AbstractController
{

    /**
     * @Route("/register", name="app_register")
     */
    public function register(
        Request $request, 
        UserPasswordEncoderInterface $passwordEncoder, 
        UserAuthenticatorInterface $authenticator, 
        SecurityAuthenticator $formAuthenticator): Response
    {
      /* Automatically generated by make:registration-form, but some changes are
         needed, like the auto-wiring of the UserAuthenticatorInterface and 
         SecurityAuthenticator */
        $user = new User();
        $form = $this->createForm(RegistrationFormType::class, $user);
        $form->handleRequest($request);

        if ($form->isSubmitted() && $form->isValid()) {
            // encode the plain password
            $user->setPassword($passwordEncoder->encodePassword($user, $form->get('password')->getData()));

            $entityManager = $this->getDoctrine()->getManager();
            $entityManager->persist($user);
            $entityManager->flush();

            // substitute the previous line (redirect response) with this one.
            return $authenticator->authenticateUser(
                $user, 
                $formAuthenticator, 
                $request); 
        }

        return $this->render('registration/register.html.twig', [
            'registrationForm' => $form->createView(),
        ]);
    }
}
