在symfony2登录成功之后进行重定向？ [英] Do something just after symfony2 login success and before redirect?

问题描述

我正在寻找一段时间，任何信息，在symfony2身份验证成功后如何做一些事情。我想重新使用用户密码才能使用bcrypt，使用旧的哈希成功验证后。我需要这样做，当我仍然有有效的纯密码，所以它应该只是在凭据检查和重定向之前。

任何线索如何实现？

我发现了Symfony中的事件调度程序，但是我找不到成功验证后是否有任何事件。

如果我尝试以这种错误的方式提出一些更好的方法，请更正我。

// 编辑

确定我发现事件在验证成功后，它被称为 security.authentication.success 。所以我现在可以附加到这个事件，但现在我不知道我的边界代码应该附加我的事件监听器？应该在 load（）方法中的 /src/Pkr/BlogUserBundle/DependencyInjection/PkrBlogUserExtension.php 中执行此操作？

解决方案

您可以指定登录成功处理程序在成功登录时执行。

例如，您的security.yml

 防火墙：
 main：
 pattern：^ / 
 form_login：
 success_handler：my.security.login_handler 
  

现在创建实现 Symfony\Component\Security\Http\Authentication\AuthenticationSuccessHandlerInterface 的类，并且成功登录后，你可以做任何你需要的，并处理重定向，你认为合适。

  / ** 
 * 
 * / 
 public function onAuthenticationSuccess（Request $ request，TokenInterface $ token）
 {
 //处理并返回响应
} 
  

然后在您的bundle的services.xml中创建一个具有该名称的服务，或者在使用新创建的处理程序的config.yml中创建一个服务。

我最初在本教程中找到了如何做到这一点：

I'm searching for a while now, for any info, on how to do something after authentication success in symfony2. I want to rehash user password to use bcrypt just after successful authentication using old hash. I need to do this when I still have valid plain password so it should be just after credentials check and before redirect.

Any clues how to achieve that?

I found something about event dispatcher in Symfony but I can't find if there is any event after successful authentication.

Please correct me if I'm trying to do this wrong way and suggest some better approach.

//EDIT

Ok I found event fired just after auth success, it's called security.authentication.success. So i can now attach to this event but now I'm not sure where in my boundle code should I attach my event listener? Should I do that in my /src/Pkr/BlogUserBundle/DependencyInjection/PkrBlogUserExtension.php in load() method?

解决方案

You can specify a login success handler to be executed on successful login.

For example, your security.yml

firewalls:
    main:
        pattern: ^/
        form_login:
            success_handler: my.security.login_handler

Now create the class which implements Symfony\Component\Security\Http\Authentication\AuthenticationSuccessHandlerInterface and on successful login, you can do whatever you need and handle the redirect as you see fit.

/**
 * 
 */
public function onAuthenticationSuccess(Request $request, TokenInterface $token)
{
    // handle it and return a response
}

Then create a service with that name in your services.xml for your bundle, or in your config.yml using the newly created handler.

I originally found out how to do this following this tutorial:
