有一个接口提交的代码如下：

 private void receive()

        {



            string result = "";

            string postData = "";

            string usernames = TxtPhone.Text.Trim();

            string password = TxtCarId.Text.Trim();

            DateTime serviceStart = System.DateTime.Now;

            switch (Request["t"])

            {

                case "create":

                    postData = "<?xml version=\"1.0\" encoding=\"UTF-8\"?>";

                    postData += "<request function=\"create\">";

                    postData += "	<params>";

                    postData += "		<param name=\"userName\">" + usernames + "</param>";

                    postData += "		<param name=\"password\">" + password + "</param>";

                    postData += "		<param name=\"serviceStart\">" + serviceStart + "</param>";

           

                    postData += "	</params>";

                    postData += "</request>";

                    break;



                case "delete":

                    postData = "<?xml version=\"1.0\" encoding=\"UTF-8\"?>";

                    postData += "<request function=\"delete\">";

                    postData += "	<params>";

                    postData += "		<param name=\"id\">" + Request["id"] + "</param>";

                    postData += "	</params>";

                    postData += "</request>";

                    break;

            }



            Encoding encoding = Encoding.UTF8;

            byte[] data = encoding.GetBytes(postData);

            System.Net.HttpWebRequest req = (System.Net.HttpWebRequest)System.Net.HttpWebRequest.Create("http://app.xiaofupo.net/api/");

            req.Method = "POST";

            req.ContentType = "application/x-www-form-urlencoded";

            req.ContentType = "text/XML";// SOAP

            req.ContentLength = data.Length;

            System.IO.Stream newStream = req.GetRequestStream();

            // 发送数据   

            newStream.Write(data, 0, data.Length);

            newStream.Close();





            // 得到响应数据

            HttpWebResponse myResponse = (HttpWebResponse)req.GetResponse();



            if (myResponse.StatusDescription == "OK")

            {

                StreamReader reader = new StreamReader(myResponse.GetResponseStream(), encoding);

                result = reader.ReadToEnd();// 得到结果

                Response.Write(result);





                XmlDocument doc = new XmlDocument();

                doc.LoadXml(result);



                string XmlMessage = doc.SelectSingleNode("/response/result/message").InnerText;

              

                Response.End();

             

            }

            else

            {

                Response.Write("响应状态" + myResponse.StatusDescription);

            }

        }

然后提交后页面如下

  <?xml version="1.0" encoding="UTF-8" ?> 

- <response>

- <result>

  <code>0</code> 

  <message>已成功添加新用户</message> 

  </result>

- <data>

  <id>178</id> 

  <indexPage>http://app.xiaofupo.net</indexPage> 

  <adminPage>http://app.xiaofupo.net</adminPage> 

  <ipAddress>223.7.18.144</ipAddress> 

  </data>

  </response>
