Windows Phone 中HttpWebRequest用法

GET请求：

首先 做一个请求

  public void httpGet()

        {

            try

            {

                //请求地址

                String url = "http://www.cnblogs.com/zhibin/";

                //创建WebRequest类

                HttpWebRequest request = HttpWebRequest.CreateHttp(new Uri(url));



                //设置请求方式GET POST

                request.Method = "GET";



                //返回应答请求异步操作的状态

                request.BeginGetResponse(responseCallback, request);

            }

            catch (WebException e)

            {

                //网络相关异常处理

            }

            catch (Exception e)

            {

                //异常处理

            }

        }

接下来 应答数据接收部分：

    private void responseCallback(IAsyncResult result)

        {

            try

            {

                //获取异步操作返回的的信息

                HttpWebRequest request = (HttpWebRequest)result.AsyncState;

                //结束对 Internet 资源的异步请求

                HttpWebResponse response = (HttpWebResponse)request.EndGetResponse(result);

                //解析应答头

                //parseRecvHeader(response.Headers);

                //获取请求体信息长度

                long contentLength = response.ContentLength;



                //获取应答码

                int statusCode = (int)response.StatusCode;

                string statusText = response.StatusDescription;



                //应答头信息验证

                using (Stream stream = response.GetResponseStream())

                {

                    //获取请求信息

                    StreamReader read = new StreamReader(stream);

                    string msg = read.ReadToEnd();

                    Deployment.Current.Dispatcher.BeginInvoke(() =>

                    {

                        textBlock1.Text = msg;

                    });

                }



            }

            catch (WebException e)

            {

                //连接失败



            }               

            catch (Exception e)

            {

                //异常处理



            }                



        }

POST请求

首先做一个链接：

     public void httpPost()

        {

            try

            {

                //请求地址

                String url = "http://www.cnblogs.com/zhibin/";

                //创建WebRequest类

                HttpWebRequest request = HttpWebRequest.CreateHttp(new Uri(url));



                //设置请求方式GET POST

                request.Method = "POST";



                //返回应答请求异步操作的状态

                request.BeginGetRequestStream(requestCallback, request);

            }

            catch (WebException e)

            {

                //网络相关异常处理

            }

            catch (Exception e)

            {

                //异常处理

            }

        }

接下来 应答数据接收部分：

      private void requestCallback(IAsyncResult result)

        {

            try

            {

                //获取异步操作返回的的信息

                HttpWebRequest request = (HttpWebRequest)result.AsyncState;

                //结束对 Internet 资源的异步请求

                StreamWriter postStream = new StreamWriter(request.EndGetRequestStream(result));

                postStream.WriteLine("作者：宇之乐");

                postStream.WriteLine("出处：http://www.cnblogs.com/zhibin/");



                //返回应答请求异步操作的状态

                request.BeginGetResponse(responseCallback, request);

            }

            catch (WebException e)

            {

                //异常处理



            }

            catch (Exception e)

            {

                //异常处理



            }

        }
