Phonegap App使用身份验证与Rails 3应用程序通信 [英] Phonegap App communicate with Rails 3 App using authentication

问题描述

我试图写一个iOS应用程序使用Phonegap与我的Rails3应用程序进行通信。我不知道如何处理身份验证。我在我的Rails应用程序中使用Devise / Warden。

我可以通过ajax在我的iOS应用程序中成功登录，但后来的电话会给我一个未经授权。似乎会在我的iOS应用程式中设定会话Cookie。

如何让我的iOS应用程式识别我的rails已验证的工作阶段？

解决方案

答案是两个。

首先我必须将它添加到我的ajax

  xhrFields：{
 withCredentials：true 
} 
  
 $> 
  $。ajax（{
 url：....，
 type：GET，
 xhrFields：{
 withCredentials：true 
}，
 complete：hideLoader，
 error：function（xhr，txt，err）{
 //你不能回来了
 window.location.hash =; 
}，
 success：function（data，status，res）{
 window.location.hash =; 
} 
} 
 
第二，我必须在Rails应用程序中将它添加到我的应用程序控制器：
  def protect_against_forgery？ 
 unless request.format.json？ 
 super 
 end 
 end 
  
 
I am trying to write an iOS app using Phonegap to communicate with my Rails3 app. I cannot figure out how to handle authentication. I am using Devise/Warden in my Rails app. 


I am able to login successfully in my iOS app via ajax but then subsequent calls are giving me a "Unauthorized". It appears that the session cookie isn't getting set in my iOS app.

How do I keep my iOS app aware of my rails authenticated session?
解决方案
The answer was two fold.

First I had to add this to my ajax requests in the iOS app:
xhrFields: {
  withCredentials: true
}
as in...
$.ajax({
    url: ....,
    type: "GET",
    xhrFields: {
        withCredentials: true
    },
    complete: hideLoader,
    error: function(xhr,txt,err) {
        // you can't get back anyways
        window.location.hash = "";
    },
    success: function(data,status,res) {
        window.location.hash = "";
    }
}); 
Second I had to add this to my Application Controller in the Rails app:
def protect_against_forgery?
  unless request.format.json?
    super
  end
end
