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

void ChilkatSample(void)
    {
    BOOL success;
    HCkXml xml;
    const char *strXml;
    int responseStatusCode;
    HCkHttp http;
    const char *endPoint;
    HCkHttpResponse resp;
    HCkXml xmlResp;

    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 = CkXml_Create();
    success = CkXml_LoadXmlFile(xml,"ukPostCodeSoap.xml");
    if (success == FALSE) {
        printf("%s\n",CkXml_lastErrorText(xml));
        CkXml_Dispose(xml);
        return;
    }

    strXml = CkXml_getXml(xml);

    http = CkHttp_Create();

    //  We'll need to add this in the HTTP header:
    //  SOAPAction: "http://www.webserviceX.NET/GetUKLocationByPostCode"
    CkHttp_SetRequestHeader(http,"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 = CkHttpResponse_Create();
    success = CkHttp_HttpStr(http,"POST",endPoint,strXml,"utf-8","text/xml",resp);
    if (success == FALSE) {
        printf("%s\n",CkHttp_lastErrorText(http));
        CkXml_Dispose(xml);
        CkHttp_Dispose(http);
        CkHttpResponse_Dispose(resp);
        return;
    }

    responseStatusCode = CkHttpResponse_getStatusCode(resp);
    //  You may wish to verify that the responseStatusCode equals 200...
    printf("Response Status Code: %d\n",responseStatusCode);

    //  You may examine the exact HTTP header sent with the POST like this:
    printf("LastHeader:\n");
    printf("%s\n",CkHttp_lastHeader(http));

    //  Examine the XML returned by the web service:
    printf("XML Response:\n");
    xmlResp = CkXml_Create();
    CkXml_LoadXml(xmlResp,CkHttpResponse_bodyStr(resp));
    printf("%s\n",CkXml_getXml(xmlResp));

    CkXml_Dispose(xml);
    CkHttp_Dispose(http);
    CkHttpResponse_Dispose(resp);
