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.

Rust

// 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.
// --------------------------------------------------------------------------------

let rest = chilkat::Rest::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/">
//   <soap:Body>
//     <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).
let b_tls = false;
let port = 80;
let b_auto_reconnect = true;
// In this particular case, it is important to connect to "wsf.cdyne.com", not "ws.cdyne.com"...

    println!("{}", rest.last_error_text());
    return;
}

// Add request headers:
let _ = rest.add_header("Content-Type", "text/xml; charset=utf-8").is_ok();
let _ = rest.add_header("SOAPAction", "http://ws.cdyne.com/WeatherWS/GetCityWeatherByZIP").is_ok();

// Build the SOAP XML request body.

    return;
};

// When successful, the response status code will equal 200.
if rest.response_status_code() != 200 {
    // Examine the request/response to see what happened.
    println!("response status code = {}", rest.response_status_code());
    println!("response status text = {}", rest.response_status_text());
