C#CS发送HTTP GET请求
try { WebRequest req = WebRequest.Create("http://127.0.0.1/test/loginsso.aspx?username=admin&password=admin"); req.Method = "POST"; //指定提交的Method,可以为POST和GET,一定要大写 //byte[] postData = System.Text.Encoding.GetEncoding("gbk").GetBytes("?username=admin&password=admin");//Post的数据 //req.ContentLength = postData.Length; Stream postStream = req.GetRequestStream(); //postStream.Write(postData, 0, postData.Length); postStream.Close(); WebResponse res = req.GetResponse(); System.Text.Encoding resEncoding = System.Text.Encoding.GetEncoding("utf-8");//接收的编码 StreamReader reader = new StreamReader(res.GetResponseStream(), resEncoding); string html = reader.ReadToEnd(); //接收的Html MessageBox.Show("=========" + html); reader.Close(); res.Close(); } catch (Exception ex) { MessageBox.Show("error"); }
.NET接收GET发送请求
Response.ContentEncoding = Encoding.GetEncoding("UTF-8"); string username = Request["username"]; string password = Request["password"]; if (username != "" && username == "admin" && password != "" && password == "admin") { Response.Write("success"); } else { Response.Write("error" + Request.Url.Host); // Response.Redirect("http://www.g.cn"); }
.NET接收后请求
System.Text.Encoding resEncoding = System.Text.Encoding.GetEncoding("utf-8");//接收的编码 StreamReader reader = new StreamReader(Request.InputStream, resEncoding); string msg = reader.ReadToEnd(); reader.Close();
