(C#) SOAP Web Service (HTTP POST)

Demonstrates how to call PostXml to call a SOAP web service.

// This example requires the Chilkat API to have been previously unlocked.
// See Global Unlock Sample for sample code.

// --------------------------------------------------------------------------------
// Also see Chilkat's Online WSDL Code Generator
// to generate code and SOAP Request and Response XML for each operation in a WSDL.
// --------------------------------------------------------------------------------

// This example uses a live web service at:
// http://www.webservicex.net/uklocation.asmx
// It gets the UK town,Postcode and County by Postcode(First Section of Post Code)

// The SOAP XML will look like this:
// <?xml version="1.0" encoding="utf-8"?>
// <soap:Envelope xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns:soap="http://schemas.xmlsoap.org/soap/envelope/">
//   <soap:Body>
//     <GetUKLocationByPostCode xmlns="http://www.webserviceX.NET">
//       <PostCode>string</PostCode>
//     </GetUKLocationByPostCode>
//   </soap:Body>
// </soap:Envelope>

// For this example's sake, we'll load the XML from a file.  We'll test using PostCode "E3".  
// The SOAP XML for this example may be downloaded from:
// http://www.chilkatsoft.com/testData/ukPostCodeSoap.xml
Chilkat.Xml xml = new Chilkat.Xml();
bool success = xml.LoadXmlFile("ukPostCodeSoap.xml");
if (success != true) {
    Debug.WriteLine(xml.LastErrorText);
    return;
}

string strXml = xml.GetXml();

int responseStatusCode;
Chilkat.Http http = new Chilkat.Http();

// We'll need to add this in the HTTP header:
// SOAPAction: "http://www.webserviceX.NET/GetUKLocationByPostCode"
http.SetRequestHeader("SOAPAction","http://www.webserviceX.NET/GetUKLocationByPostCode");

// Some services expect the content-type in the HTTP header to be "application/xml" while
// other expect text/xml.  The default sent by Chilkat is "application/xml", but this web service
// expects "text/xml".  Therefore, change the content-type:
http.SetRequestHeader("Content-Type","text/xml; charset=utf-8");

// The endpoint for this soap service is:
string endPoint = "http://www.webservicex.net/uklocation.asmx";

// Note: This particular web service was live and functioning at the time this example
// was written.  It is possible that as time progresses, this web service will no longer
// be availble...
Chilkat.HttpResponse resp = http.PostXml(endPoint,strXml,"utf-8");
if (http.LastMethodSuccess != true) {
    Debug.WriteLine(http.LastErrorText);
    Debug.WriteLine("LastHeader:");
    Debug.WriteLine(http.LastHeader);
    return;
}

responseStatusCode = resp.StatusCode;
// You may wish to verify that the responseStatusCode equals 200...
Debug.WriteLine("Response Status Code: " + Convert.ToString(responseStatusCode));

// You may examine the exact HTTP header sent with the POST like this:
Debug.WriteLine("LastHeader:");
Debug.WriteLine(http.LastHeader);

// Examine the XML returned by the web service:
Debug.WriteLine("XML Response:");
Chilkat.Xml xmlResp = new Chilkat.Xml();
xmlResp.LoadXml(resp.BodyStr);
Debug.WriteLine(xmlResp.GetXml());
