(Lianja) Making SOAP Requests using the REST API

There's no reason a SOAP request cannot be sent using the REST API. It's only a matter of adding a SOAP specific header, and providing the SOAP XML request body. The response body is the SOAP response XML.

This example sends a request to ws.cdyne.com to get city weather by zip code.

// Demonstrates how to do a SOAP request using the REST API.

// 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.

loRest = createobject("CkRest")

// This is the request to be sent:

// POST /WeatherWS/Weather.asmx HTTP/1.1
// Host: wsf.cdyne.com
// Content-Type: text/xml; charset=utf-8
// Content-Length: length
// SOAPAction: "http://ws.cdyne.com/WeatherWS/GetCityWeatherByZIP"
// 
// <?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/">

//       <ZIP>string</ZIP>
//     </GetCityWeatherByZIP>
//   </soap:Body>
// </soap:Envelope>

// Note: The application does not need to set the Host or Content-Length headers.
// Chilkat will automatically add these headers.

// Make the initial connection (without sending a request yet).

// Add request headers:
