SOAP Web Service (HTTP POST)

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

Use ChilkatAx-win32.pkg

Procedure Test
    Boolean iSuccess
    Handle hoXml
    String sStrXml
    Integer iResponseStatusCode
    Handle hoHttp
    String sEndPoint
    Variant vResp
    Handle hoResp
    Handle hoXmlResp
    String sTemp1

    Move False To iSuccess

    // 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
    Get Create (RefClass(cComChilkatXml)) To hoXml
    If (Not(IsComObjectCreated(hoXml))) Begin
        Send CreateComObject of hoXml
    End
    Get ComLoadXmlFile Of hoXml "ukPostCodeSoap.xml" To iSuccess
    If (iSuccess = False) Begin
        Get ComLastErrorText Of hoXml To sTemp1
        Showln sTemp1
        Procedure_Return
    End

    Get ComGetXml Of hoXml To sStrXml

    Get Create (RefClass(cComChilkatHttp)) To hoHttp
    If (Not(IsComObjectCreated(hoHttp))) Begin
        Send CreateComObject of hoHttp
    End

    // We'll need to add this in the HTTP header:
    // SOAPAction: "http://www.webserviceX.NET/GetUKLocationByPostCode"
    Send ComSetRequestHeader To hoHttp "SOAPAction" "http://www.webserviceX.NET/GetUKLocationByPostCode"

    // The endpoint for this soap service is:
    Move "http://www.webservicex.net/uklocation.asmx" To sEndPoint

    // 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...
    Get Create (RefClass(cComChilkatHttpResponse)) To hoResp
    If (Not(IsComObjectCreated(hoResp))) Begin
        Send CreateComObject of hoResp
    End
    Get pvComObject of hoResp to vResp
    Get ComHttpStr Of hoHttp "POST" sEndPoint sStrXml "utf-8" "text/xml" vResp To iSuccess
    If (iSuccess = False) Begin
        Get ComLastErrorText Of hoHttp To sTemp1
        Showln sTemp1
        Procedure_Return
    End

    Get ComStatusCode Of hoResp To iResponseStatusCode
    // You may wish to verify that the responseStatusCode equals 200...
    Showln "Response Status Code: " iResponseStatusCode

    // You may examine the exact HTTP header sent with the POST like this:
    Showln "LastHeader:"
    Get ComLastHeader Of hoHttp To sTemp1
    Showln sTemp1

    // Examine the XML returned by the web service:
    Showln "XML Response:"
    Get Create (RefClass(cComChilkatXml)) To hoXmlResp
    If (Not(IsComObjectCreated(hoXmlResp))) Begin
        Send CreateComObject of hoXmlResp
    End
    Get ComBodyStr Of hoResp To sTemp1
    Get ComLoadXml Of hoXmlResp sTemp1 To iSuccess
    Get ComGetXml Of hoXmlResp To sTemp1
    Showln sTemp1
