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.

Go

    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.NewRest()

    // 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).
    bTls := false
    port := 80
    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 {
        fmt.Println(rest.LastErrorText())

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