Making SOAP Requests using the REST API

See more REST Examples

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.

$oRest = ObjCreate("Chilkat.Rest")

;  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).
