SOAP Web Service (HTTP POST)

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

llSuccess = .F.

// 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
loXml = createobject("CkXml")
llSuccess = loXml.LoadXmlFile("ukPostCodeSoap.xml")
if (llSuccess = .F.) then
    ? loXml.LastErrorText
    release loXml
    return
endif

lcStrXml = loXml.GetXml()

loHttp = createobject("CkHttp")

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

// The endpoint for this soap service is:
lcEndPoint = "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...
loResp = createobject("CkHttpResponse")
llSuccess = loHttp.HttpStr("POST",lcEndPoint,lcStrXml,"utf-8","text/xml",loResp)
if (llSuccess = .F.) then
    ? loHttp.LastErrorText
    release loXml
    release loHttp
    release loResp
    return
endif

lnResponseStatusCode = loResp.StatusCode
// You may wish to verify that the responseStatusCode equals 200...
? "Response Status Code: " + str(lnResponseStatusCode)

// You may examine the exact HTTP header sent with the POST like this:
? "LastHeader:"
? loHttp.LastHeader

// Examine the XML returned by the web service:
? "XML Response:"
loXmlResp = createobject("CkXml")
loXmlResp.LoadXml(loResp.BodyStr)
? loXmlResp.GetXml()
