Winform 程序以POST形式访问网站

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;

 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();
