我有一个UITextField,当我在UITextField中写东西并按下更新按钮时,我想更新我的服务器,我使用了AFNetworking,但是我有一个错误:

 Domain=com.alamofire.error.serialization.response Code=-1011 
 "Request failed: internal server error (500)
{ status code: 500, headers {
"Access-Control-Allow-Headers" = "Origin, X-Requested-With, Content-Type, Accept";
"Access-Control-Allow-Methods" = "OPTIONS,GET,POST,PUT,DELETE";
"Access-Control-Allow-Origin" = "*";
Connection = "keep-alive";
"Content-Type" = "text/plain";
Date = "Thu, 24 Jul 2014 00:41:56 GMT";
Server = Cowboy;
"Transfer-Encoding" = Identity;
Via = "1.1 vegur";
"X-Powered-By" = Express;
} }, NSLocalizedDescription=Request failed: internal server error (500)}

这是我的更新按钮代码:

AFHTTPRequestOperationManager *manager = [AFHTTPRequestOperationManager manager];
manager.responseSerializer = [AFHTTPResponseSerializer serializer];
manager.requestSerializer = [AFJSONRequestSerializer serializer];


NSDictionary *params = @ …

我在服务器上有json文件,其余的APLI,我想与服务器通信,现在我用这个方法连接到服务器并在我的viewdidload方法中调用它,我的问题是,最好的方法是什么,可以我用单身人士？如果是的应该怎么样？提前致谢!

感谢答案部分中的任何代码建议.
