Symfony2：新闻稿订阅

我需要让订阅时事通讯的事情运作起来。我使用的逻辑是，当用户提交他的电子邮件时，我检查是否已经有用户通过电子邮件注册到该站点。如果是，我检查他是否订阅了时事通讯，并进行相应的订阅。如果电子邮件不在注册用户列表中，那么我有一个匿名用户通讯表。我在这里检查他是否已订阅，并执行必要的操作

以下是我的控制器操作代码：

/**
 * @Route("/newsletter/", name="site_newsletter")
 * @return array
 */
public function newsletterSubscriptionAction(httpRequest $request)
{  
    $email = $request->request->get('email');

    try {

        $email = $request->request->get('email');
        $em = $this->getDoctrine()->getEntityManager();
        $query = $em->createQuery(
            'SELECT u FROM MyBundle:User u WHERE u.email = :email'
        )->setParameter('email', $email);

        $user = $query->getSingleResult();

        if(!is_object($user)){ //this means anonymous user not registered to site
            $em = $this->getDoctrine()->getEntityManager();
            $query = $em->createQuery(
                'SELECT n FROM MyBundle:Newsletter n WHERE n.email = :email AND n.isSubscribed = 1'
            )->setParameter('email', $email);

            $record = $query->getSingleResult();

            if($record){
                $msg = "You are already subscribed!";
            }else{
                $newsletter = new Newsletter();
                $newsletter->setEmail($email);
                $newsletter->setIsSubscribed(true);

                $em = $this->getDoctrine()->getEntityManager();
                $em->persist($newsletter);
                $em->flush();

                $msg = "You have been subscribed to our newsletter! Thank You.";
            }
        }else{
            if($user->getNewsletterSubscription()){
                $msg = "You are already subscribed!";
            }else{
                $user->setNewsletterSubscription(1);
                $em = $this->getDoctrine()->getEntityManager();
                $em->flush();                    
                $msg = "You have been subscribed to our newsletter! Thank You.";
            }                
        }

    }
    catch (\Exception $e) {
        $msg = 'Some problem occured. Please try again later';
    }

    if ($this->getRequest()->isXmlHttpRequest()) {
        return new \Symfony\Component\HttpFoundation\Response($msg);
        return array('msg' => $msg);
    }

}

我正在使用ajax调用此控制器操作。这不管用。返回ajax的数据被重定向到登录页面

我使用FOSUSerBundle来管理用户。这会引起什么问题吗？实施它的最佳方式是什么

提前谢谢

听起来您需要向其他用户授予使用订阅路由的权限

在security.yml文件中，添加如下内容：

security:
    access_control:
        - { path: ^/subscribe, roles: IS_AUTHENTICATED_ANONYMOUSLY }

嘿推我超过2000次。谢谢
