SOAP Web Service (HTTP POST)

Demonstrates how to call PostXml to call a SOAP web service. Go

    success := false

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

    // This example uses a live web service at:
    // http://www.webservicex.net/uklocation.asmx
    // It gets the UK town,Postcode and County by Postcode(First Section of Post Code)

    // The SOAP XML will look like this:
    // <?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>
    //     <GetUKLocationByPostCode xmlns="http://www.webserviceX.NET">
    //       <PostCode>string</PostCode>
    //     </GetUKLocationByPostCode>
    //   </soap:Body>
    // </soap:Envelope>

    // For this example's sake, we'll load the XML from a file.  We'll test using PostCode "E3".  
    // The SOAP XML for this example may be downloaded from:
    // http://www.chilkatsoft.com/testData/ukPostCodeSoap.xml
    xml := chilkat.NewXml()
    success = xml.LoadXmlFile("ukPostCodeSoap.xml")
    if success == false {
        fmt.Println(xml.LastErrorText())
        xml.DisposeXml()
        return
    }

    strXml := xml.GetXml()

    var responseStatusCode int
    http := chilkat.NewHttp()

    // We'll need to add this in the HTTP header:
    // SOAPAction: "http://www.webserviceX.NET/GetUKLocationByPostCode"
    http.SetRequestHeader("SOAPAction","http://www.webserviceX.NET/GetUKLocationByPostCode")

    // The endpoint for this soap service is:
    endPoint := "http://www.webservicex.net/uklocation.asmx"

    // Note: This particular web service was live and functioning at the time this example
    // was written.  It is possible that as time progresses, this web service will no longer
    // be availble...
    resp := chilkat.NewHttpResponse()
    success = http.HttpStr("POST",endPoint,*strXml,"utf-8","text/xml",resp)
    if success == false {
        fmt.Println(http.LastErrorText())
        xml.DisposeXml()
        http.DisposeHttp()
        resp.DisposeHttpResponse()
        return
    }

    responseStatusCode = resp.StatusCode()
    // You may wish to verify that the responseStatusCode equals 200...
    fmt.Println("Response Status Code: ", responseStatusCode)

    // You may examine the exact HTTP header sent with the POST like this:
    fmt.Println("LastHeader:")
    fmt.Println(http.LastHeader())

    // Examine the XML returned by the web service:
    fmt.Println("XML Response:")
    xmlResp := chilkat.NewXml()
    xmlResp.LoadXml(resp.BodyStr())
    fmt.Println(*xmlResp.GetXml())

    // Use this online tool to generate parsing code from response XML: 
    // Generate Parsing Code from XML

    xml.DisposeXml()
    http.DisposeHttp()
    resp.DisposeHttpResponse()
    xmlResp.DisposeXml()
