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 } }
