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.

C#

bool 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.

Chilkat.Rest rest = new 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/">

//      <GetCityWeatherByZIP xmlns="http://ws.cdyne.com/WeatherWS/">
//        <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).
bool bTls = false;
int port = 80;
bool bAutoReconnect = true;
//  In this particular case, it is important to connect to "wsf.cdyne.com", not "ws.cdyne.com"...
success = rest.Connect("wsf.cdyne.com",port,bTls,bAutoReconnect);
if (success != true) {
    Debug.WriteLine(rest.LastErrorText);
    return;
}

//  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.
