每次更新ADNetworking都要改，唉
下面是错误信息：
获取服务器响应出错

NSLocalizedDescription=Requestfailed: unacceptable content-type: text/html}
对应到自己的项目里面，我用的是AFNetworking这套网络请求包，需要改的是：
AFURLResponseSerialization.m文件
223行：
self.acceptableContentTypes =[NSSetsetWithObjects:@"application/json", @"text/html"
,@"text/json",@"text/javascript", nil];
加上@"text/html"部分，其实就是添加一种服务器返回的数据格式。
