通过http请求传递xml流和接收xml流的代码示例

Answer 1

string sampleRequest = @"
<?xml version=""1.0""?>
你的节点
";
this.Response = ReceiveData(sampleRequest, Server);            // Load Xml into a XmlDocument object
            XmlDocument XmlResponse = new XmlDocument();
            try
            {
                XmlResponse .LoadXml(this.Response);
            }
            catch
            {
            }private string ReceiveData(string req, string Server)
        {
            ASCIIEncoding encoding = new ASCIIEncoding();
            byte[] data = encoding.GetBytes(req); // Request
            HttpWebRequest r = (HttpWebRequest)WebRequest.Create(Server); 
            r.Method = "POST";
            r.ContentType = "application/x-www-form-urlencoded";
            r.ContentLength = data.Length;
            Stream requestStream = r.GetRequestStream();
            r.Write(data, 0, data.Length);
            r.Close();
            WebResponse myResponse = null;
            string response;
            try
            {
                myResponse = r.GetResponse();
                using (StreamReader sr = new StreamReader(myResponse .GetResponseStream()))
                {
                    response = sr.ReadToEnd();
                    sr.Close();
                }
            }
            catch (Exception exc)
            {
                response = exc.ToString();
            }            return response;
        }

Answer 2

string xmlFileName = Server.MapPath("new2.xml");
            HttpWebRequest req = null;
          
                //设置要POST到的页面URL
                string url = "http://www.XX.com/Receive2.aspx";
                //创建一个HttpWebRequest对象
                req = (HttpWebRequest)HttpWebRequest.Create(url);
                //设置它提交数据的方式post
                req.Method = "POST";
                //设置 Content-type HTTP 标头的值
                req.ContentType = "application/x-www-form-urlencoded";// "application/x-www-form-urlencoded;charset=gb2312";
                using (StreamWriter requestWriter = new StreamWriter(req.GetRequestStream()))
                {
                    //定义一个StreamReader对象，用于读取xml文件的内容
                    StreamReader reader = new StreamReader(xmlFileName);
                    string ret = reader.ReadToEnd();
                    reader.Close();
                    requestWriter.WriteLine(ret);//将读取的内容写入到RequestStream中。
                }
备注 为什么不对呢 http://www.XX.com/Receive2.aspx这个地址都没有接收到任何东西
