答

尝试使用以下 HTTPHeaderFields 进行设置.

Try setting with the following HTTPHeaderFields.

[request setValue:@"application/x-www-form-urlencoded" forHTTPHeaderField:@"Content-Type"];     
[request setValue:@"UTF-8" forHTTPHeaderField:@"charset"];      
[request setValue:@"XMLHttpRequest" forHTTPHeaderField:@"X-Requested-With"];

我相信登录调用可能是"GET"方法，而不是"POST".

I believe that the login call may be a "GET" method instead of "POST".

再次确认您拨打电话的服务器URL.

Once again confirm with the server URL that you make the call.

谢谢.
