本例介绍了Winform程序发送POST请求访问页面，主要使用到了HttpWebRequest和HttpWebResponse这两个对象。
程序主要代码如下：
代码 1 using System.Net; 2 using System.IO; 3 4 5 //创建HttpWebRequest对象 6 HttpWebRequest request = (HttpWebRequest)HttpWebRequest.Create("http://192.168.0.1");//目标主机ip地址 7 8 //模拟POST的数据 9 string postData = string.Empty;10 postData += "user=" + "test1";11 postData += "&password=" + "123";12 Encoding utf8=Encoding.UTF8;13 byte[] data = utf8.GetBytes(postData);14 15 //设置请求头信息16 string cookieheader = string.Empty;17 CookieContainer cookieCon = new CookieContainer();18 request.Method = "POST";19 //设置cookie，若没有可以不设置20 request.CookieContainer = cookieCon;21 request.ContentType = "application/x-www-form-urlencoded";22 request.ContentLength = data.Length;23 Stream newStream = request.GetRequestStream();24 //把请求数据 写入请求流中25 newStream.Write(data, 0, data.Length);26 newStream.Close();27 28 29 //获得HttpWebResponse对象30 HttpWebResponse response = (HttpWebResponse)request.GetResponse();31 32 Console.Write("Content length is {0}", response.ContentLength + "\r\n");33 Console.Write("Content type is {0}", response.ContentType + "\r\n");34 35 //获得响应流36 Stream receiveStream = response.GetResponseStream();37 StreamReader readStream = new StreamReader(receiveStream, Encoding.UTF8);38 //输入响应流信息39 Console.Write("Response stream received.\r\n");40 Console.Write(readStream.ReadToEnd() + "\r\n");41 42 response.Close();43 receiveStream.Close();44 readStream.Close();posted on 2012-02-12 20:26 Johnny_Z 阅读( ...) 评论( ...) 编辑 收藏
