c#怎么通过http post报文调用web接口

Answer 1

string url = "http://127.0.0.1/page.aspx";
string postData = "id=1&user=hzt";

WebRequest request = WebRequest.Create(url);
request.Method = "Post";
request.ContentType = "application/x-www-form-urlencoded";
request.ContentLength = postData.Length;
StreamWriter sw = new StreamWriter(request.GetRequestStream());
sw.Write(postData);
sw.Flush();

WebResponse response = request.GetResponse();
Stream s = response.GetResponseStream();
StreamReader sr = new StreamReader(s, Encoding.GetEncoding("gb2312"));
MessageBox.Show(sr.ReadToEnd());

sw.Dispose();
sw.Close();
sr.Dispose();
sr.Close();
s.Dispose();
s.Close();
