Symfony2 - 试图了解 FOSUserBundle 注册确认

Question

我是 Symfony 的新手，现在我几乎了解了基础知识，现在我正在深入研究事件和事件监听器。

我了解到，当用户通过 FOSUserBundle 注册时，会在 registerAction()

中调度三个事件

REGISTRATION_INITIALIZE
REGISTRATION_SUCCESS
REGISTRATION_COMPLETED

这是registerAction代码

public function registerAction(Request $request)
    {
        /** @var $formFactory \FOS\UserBundle\Form\Factory\FactoryInterface */
        $formFactory = $this->get('fos_user.registration.form.factory');
        /** @var $userManager \FOS\UserBundle\Model\UserManagerInterface */
        $userManager = $this->get('fos_user.user_manager');
        /** @var $dispatcher \Symfony\Component\EventDispatcher\EventDispatcherInterface */
        $dispatcher = $this->get('event_dispatcher');

        $user = $userManager->createUser();
        $user->setEnabled(true);

        $event = new GetResponseUserEvent($user, $request);
        $dispatcher->dispatch(FOSUserEvents::REGISTRATION_INITIALIZE, $event);

        if (null !== $event->getResponse()) {
            return $event->getResponse();
        }

        $form = $formFactory->createForm();
        $form->setData($user);

        $form->handleRequest($request);

        if ($form->isValid()) {
            $event = new FormEvent($form, $request);
            $dispatcher->dispatch(FOSUserEvents::REGISTRATION_SUCCESS, $event);

            $userManager->updateUser($user);

            if (null === $response = $event->getResponse()) {
                $url = $this->generateUrl('fos_user_registration_confirmed');
                $response = new RedirectResponse($url);
            }

            $dispatcher->dispatch(FOSUserEvents::REGISTRATION_COMPLETED, new FilterUserResponseEvent($user, $request, $response));

            return $response;
        }

        return $this->render('FOSUserBundle:Registration:register.html.twig', array(
            'form' => $form->createView(),
        ));
    }

现在在 config.yml 中，我们可以设置配置，这样用户在激活帐户之前需要确认他们的电子邮件地址，这就是我迷路的地方

fos_user:
    registration:
        confirmation:
            enabled: true

我正在查看 EmailConfirmationListener，它听取 REGISTRATION_SUCCESS 并且在这段代码中我没有发现任何东西可以告诉我它是如何读取 config.yml 中的 confirmation

如果有人能向我解释如何根据 confirmation enabled 状态触发此侦听器，我将不胜感激。

symfony doc解释

In order to load service configuration, you have to create a Dependency Injection (DI) Extension for your bundle

我在存储库中进行了搜索，you can see，FOSUserExtension.php 文件加载了一个包含侦听器声明的服务文件。
