GTA XML API SearchHotelPriceRequest,ItemInformationDownloadRequest

09年做过GTA的酒店项目，成功地实现了全套业务流程。

由于某种不能透露的原因，现在又要做这件事。翻出了当年的代码，其实很简单，不知道为什么现在的同事对着Document唯一能做的事情就是发呆......

GTA 酒店接口是通过POST方法传递一个XML来实现数据交互的，现把SearchHotelPriceRequest的实现代码粘贴出来，希望能帮到后来人。

稍后会张贴出ItemInformationDownloadRequest的代码......

        public System.Xml.XmlDocument SendRequestXmlData()         {             string EmailAddress = "GTA授权邮件地址";             string ClientPassword = "密码";             string ClientID = "客户号";             string Language = "语言代码";             XmlElement XMLRequest, XMLHeader, XMLNode, XMLChildNode, XMLBody, XMLGrandChild;             XmlDocument XMLDoc;             string strCheckInDate = DateTime.Now.AddDays(20).ToShortDateString();

            XMLDoc = new XmlDocument();             XMLRequest = XMLDoc.CreateElement("Request");             XMLHeader = XMLDoc.CreateElement("Source");

            XMLNode = XMLDoc.CreateElement("RequestorID");             XMLNode.SetAttribute("Client", ClientID);             XMLNode.SetAttribute("EMailAddress", EmailAddress);             XMLNode.SetAttribute("Password", ClientPassword);             XMLHeader.AppendChild(XMLNode);

            XMLNode = XMLDoc.CreateElement("RequestorPreferences");             XMLNode.SetAttribute("Language", Language);             XMLChildNode = XMLDoc.CreateElement("RequestMode");             XMLChildNode.InnerText = "SYNCHRONOUS";             XMLNode.AppendChild(XMLChildNode);             XMLHeader.AppendChild(XMLNode);

            XMLBody = XMLDoc.CreateElement("RequestDetails");             XMLNode = XMLDoc.CreateElement("SearchHotelPriceRequest");             XMLChildNode = XMLDoc.CreateElement("ItemDestination");             XMLChildNode.SetAttribute("DestinationType", "city");             XMLChildNode.SetAttribute("DestinationCode", "CAN");             XMLNode.AppendChild(XMLChildNode);             XMLChildNode = XMLDoc.CreateElement("PeriodOfStay");             XMLGrandChild = XMLDoc.CreateElement("CheckInDate");             XMLGrandChild.InnerText = strCheckInDate;             XMLChildNode.AppendChild(XMLGrandChild);             XMLGrandChild = XMLDoc.CreateElement("Duration");             XMLGrandChild.InnerText = "2";             XMLChildNode.AppendChild(XMLGrandChild);             XMLNode.AppendChild(XMLChildNode);             XMLChildNode = XMLDoc.CreateElement("Rooms");             XMLGrandChild = XMLDoc.CreateElement("Room");             XMLGrandChild.SetAttribute("Code", "db");             XMLGrandChild.SetAttribute("NumberOfRooms", "1");             XMLChildNode.AppendChild(XMLGrandChild);             XMLNode.AppendChild(XMLChildNode);             XMLBody.AppendChild(XMLNode);

            XMLRequest.AppendChild(XMLHeader);             XMLRequest.AppendChild(XMLBody);             XMLDoc.AppendChild(XMLRequest);

            System.Xml.XmlDocument XMLDoc1 = new System.Xml.XmlDocument();             System.Text.ASCIIEncoding encoding = new System.Text.ASCIIEncoding();             Byte[] byte1 = encoding.GetBytes(XMLDoc.OuterXml);             WebRequest HttpWReq = WebRequest.Create("https://rbs.gta-travel.com/rbshkapi/RequestListenerServlet");             HttpWReq.ContentType = "text/xml";             HttpWReq.ContentLength = XMLDoc.OuterXml.Length;             HttpWReq.Method = "POST";             HttpWReq.Timeout = 1200000;             System.IO.Stream StreamData = HttpWReq.GetRequestStream();             StreamData.Write(byte1, 0, byte1.Length);             WebResponse HttpWRes = HttpWReq.GetResponse();             System.IO.Stream receiveStream = HttpWRes.GetResponseStream();             XMLDoc1.Load(receiveStream);             StreamData.Close();

            XmlNodeList nodeList = XMLDoc1.GetElementsByTagName("Error");             if (nodeList.Count > 0)             {                 string errorId = nodeList[0].SelectSingleNode("ErrorId").InnerText;                 string errorText = nodeList[0].SelectSingleNode("ErrorText").InnerText;                 throw new Exception("错误ID=" + errorId + "，错误内容=" + errorText);             }             return XMLDoc1;         }
