wp8 使用http post 返回NotFound

txwdyyy001 2014-04-18 05:39:12

一直用的HttpWebRequest的方法post,原来都没有问题。
最近一个项目有个接口需要大概90秒左右才能返回数据。
但测试在60左右就会报notfound的错误。换了一个http类库System.Net.Http同样60秒左右这个接口会返回404.
但是在winform中用同样的代码发送同样的数据，可以正常返回。HttpWebRequest在wp上是2.0的在winForm上是4.0版本的。
请帮忙分析一下问及提供一些解决思路，谢谢。

下面为代码



/// <summary>

        /// POST数据

        /// </summary>

        /// <param name="strData">要POST的数据</param>

        public void PostHttpWebRequest(string strData)

        {

            strMethod = "POST";

            strSendData = strData;



            webRequest = HttpWebRequest.Create(mUrl);

            webRequest.Method = strMethod;

            //webRequest.ContentType = "multipart/form-data";

            //webRequest.UseDefaultCredentials = true;

            

            var resBeginSend = (IAsyncResult)webRequest.BeginGetRequestStream(RequestSendCallback, webRequest);

        }



        /// <summary>

        /// GET数据

        /// </summary>

        public void GetHttpWebRequest()

        {

            strMethod = "GET";

            webRequest = HttpWebRequest.Create(mUrl);

            webRequest.Method = strMethod;



            // get 方法直接到Response函数

            var resBeginSend = (IAsyncResult)webRequest.BeginGetResponse(MYTestResponseCallback, webRequest);

        }



        /// <summary>

        /// Post方式返回数据响应

        /// </summary>

                Stream newStream = request.EndGetRequestStream(result);

                var resGetResp = (IAsyncResult)request.BeginGetResponse(MYTestResponseCallback, request);

            }

            catch (Exception ex)

            { }

        }
