(DataFlex) SOAP Web Service (HTTP POST)Demonstrates how to call PostXml to call a SOAP web service. Note: This example requires Chilkat v11.0.0 or greater.
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.
