Php 在symfony 2中向邮件发送登录名和密码

如何在symfony 2中向电子邮件发送登录名和密码？ 我需要注册帐户后，登录名和密码被发送到用户指定的邮件！ 由于某种原因，我无法实施 提前感谢：）！ 代码如下：

class RegController extends Controller
{
    private $eventDispatcher;
    private $formFactory;
    private $userManager;
    private $tokenStorage;

    public function __construct(EventDispatcherInterface $eventDispatcher, FactoryInterface $formFactory, UserManagerInterface $userManager, TokenStorageInterface $tokenStorage)
    {
        $this->eventDispatcher = $eventDispatcher;
        $this->formFactory = $formFactory;
        $this->userManager = $userManager;
        $this->tokenStorage = $tokenStorage;
    }
    public function registerAction(Request $request)
    {

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

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

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

        $form = $this->createForm(RegistrationType::class, $user);
        $form->setData($user);

        $form->handleRequest($request);

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

                $this->userManager->updateUser($user);

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

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

            }

            $event = new FormEvent($form, $request);
            $this->eventDispatcher->dispatch(FOSUserEvents::REGISTRATION_FAILURE, $event);

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

            }


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


}

如何做对？救命啊

你发送电子邮件的代码在哪里？它不在那里，我删除了它，因为它不起作用！如果有必要，我可以再找到它！这回答了你的问题吗@Shibon不，我试过了，没用！！！您是否使用任何捆绑包进行用户注册，或者尝试FOSUserbundle，或者添加用于发送邮件的代码
