从外部表单接收POST [英] Receive POST from External Form

问题描述

我在另一个网站（使用不同的后端）上有一个表单，我希望能够发布到我的Rails应用程序（在不同的域中）。

• 如何为外部表单生成有效的真实性标记，以便我的Rails应用程序可以接受它？ - 我还需要做些什么才能做到这一点？除了真实性标记之外，其余部分对我来说似乎很简单......

感谢您的帮助！

解决方案

您无法从Rails应用程序外部生成真实标记。
您可以做的是禁用令牌保护功能 a>仅用于此操作，并使用基于before_filter的自定义实现。

  skip_before_filter：verify_authenticity_token，：only => ：my_action 
 before_filter：verify_custom_authenticity_token，：only => ：my_action 
 $ b def verify_custom_authenticity_token 
＃检查请求是否来自信任源
结束
  

I have a form on another website (using a different backend) that I want to be able to POST to my Rails application (on a different domain).

• How do I generate a valid authenticity token for the external form so that my Rails app will accept it?
• Assuming I can do the answer to the above question--is there anything else special I need to do to make this work? Apart from the authenticity token, the rest of it seems pretty straightforward to me...

Thanks for the help!

解决方案

You can't generate an autenticity token from outside your Rails app. What you can do, is to disable the token protection only for this action and use a custom implementation based on a before_filter.

skip_before_filter :verify_authenticity_token, :only => :my_action
before_filter :verify_custom_authenticity_token, :only => :my_action

def verify_custom_authenticity_token
  # checks whether the request comes from a trusted source
end
