Use HostelsClub Search Web-Service in ASP.NET

HostelsClub is one of the worlds larges search engine to search hotels, hostels, rooms and also provide booking of it. so if you want to integrate such a functionality in your website then you will have to take authentication from hostelclub and he will provide you Authentication id and password for Test (free of cost) and later you can upgrade to "Production" version (it will take some percentage in booking cost's profit).

HostelsClub provides you API Library and sample application in PHP to get connect with hostelsclub. But they don't have any API Library or application in ASP.NET. so if you want to do this, below sample can help you.

Through this sample you can PING the hostelsclub web-service search engine.


string targetUri = "http://www.hostelspoint.com/xml/xml.php";
System.Xml.XmlDocument reqDoc = new System.Xml.XmlDocument();
reqDoc.Load(Server.MapPath("~\\ping.xml"));//this is your xml file which u want to send to hostelsclub for ping
string formParameterName = "OTA_request";
string xmlData = reqDoc.InnerXml;
HttpWebRequest request = (HttpWebRequest)WebRequest.Create(targetUri);
string sendString = formParameterName + "=" + HttpUtility.UrlEncode(xmlData);
//string sendString = HttpUtility.UrlEncode(xmlData);

byte[] byteStream;
byteStream = System.Text.Encoding.UTF8.GetBytes(sendString);
request.Method = "POST";
request.ContentType = "application/x-www-form-urlencoded";
request.ContentLength = byteStream.LongLength;

using (Stream writer = request.GetRequestStream())
{
writer.Write(byteStream, 0, (int)request.ContentLength);
writer.Flush();
}

HttpWebResponse resp = (HttpWebResponse)request.GetResponse();
string respStr = "";
if (request.HaveResponse)
{
if (resp.StatusCode == HttpStatusCode.OK || resp.StatusCode == HttpStatusCode.Accepted)
{
StreamReader respReader = new StreamReader(resp.GetResponseStream());
respStr = respReader.ReadToEnd(); // get the xml result in the string object

XmlDocument doc = new XmlDocument();
doc.LoadXml(respStr);
Label1.Text = doc.InnerXml.ToString();


}
}
