Facebook iOS SDK 3.1：“错误：HTTP状态代码：400” [英] Facebook iOS SDK 3.1: "Error: HTTP status code: 400"

问题描述

我正在使用iOS6模拟器在Xcode 4.5GM上运行Facebook SDK 3.1。我在iOS设置中连接到FB，并使用新的iOS6 FBConnect UI在我的应用程序中成功FB连接。我有一个访问令牌，可以看到我的朋友，发送应用程序请求，发布到我的墙上等等。但是，每次我启动任何类型的FBURLConnection，我看到这打印到我的控制台：

 错误：HTTP状态代码：400 
  

当我打印出错误时，我进入了FB代码并打印了回复，我得到：

  {
 body = {
 error = {
 code = 100; 
 message =（＃100）'mobile_app_install'活动需要参数'归因'; 
 type = OAuthException; 
}; 
}; 
 code = 400; 
} 
  

有谁知道如何解决这个问题？所有功能似乎都可以正常工作，但是我一直看到这个垃圾邮件我的控制台。

解决方案

这个错误反映了服务器上的一个错误，在3.1版本发布后不久就修复了。在这一点上，应该没有更多的失败来自这个请求。希望这有帮助！

I am running the Facebook SDK 3.1 on Xcode 4.5GM with iOS6 simulator. I connect to FB in the iOS settings and successfully FB connect in my app using the new iOS6 FBConnect UI. I have an access token, can see my friends, send app requests, post to my wall, etc. However, every time I initiate any sort of FBURLConnection is made, I see this printed to my console:

Error: HTTP status code: 400

I went into the FB code and printed the reponse when this error is printed and I get:

{
    body =     {
        error =         {
            code = 100;
            message = "(#100) The parameter 'attribution' is required for the 'mobile_app_install' activity";
            type = OAuthException;
        };
    };
    code = 400;
}

Does anyone know how to resolve this? All functionality seems to work, but I keep seeing this spam my console.

解决方案

This error reflected a bug on the server, which was fixed shortly after the 3.1 release was published. At this point there should be no more failures coming from this request. Hope this helps!
