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.

require 'chilkat'

success = false

# 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.

rest = Chilkat::CkRest.new()

# 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:
success = rest.AddHeader("Content-Type","text/xml; charset=utf-8")
success = rest.AddHeader("SOAPAction","http://ws.cdyne.com/WeatherWS/GetCityWeatherByZIP")

# Build the SOAP XML request body.
