(Node.js) 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.

var os = require('os');
if (os.platform() == 'win32') {  
    if (os.arch() == 'ia32') {

    } else {

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

    // This example requires the Chilkat API to have been previously unlocked.
