我无法弄清楚，为什么我无法登录。

我收到错误消息“ Controller 必须返回响应(给定为空)。您是否忘记在 Controller 中的某处添加返回语句？”

(如果我取消注释，则从 SecurityController 打印一条消息，loginCheckAction(路由 sec_l​​ogin_check)，据我所知永远不应该打印(=执行)。

我已经删除了翻译，从登录路由中删除了所有前缀(如安全性)并创建了一个新项目。尽管如此，我仍然收到此错误。

最佳答案

我认为问题出在 loginCheckAction 中，您应该返回一些不是打印或测试响应的内容:

public function loginCheckAction(){
   throw new \RuntimeException('You must configure the check path to be handled by the firewall using form_login in your security firewall configuration.');
}

关于php - Symfony2，无法登录，可能是翻译的原因？，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/40715116/
