(Unicode C) 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.
#include <C_CkXmlW.h> #include <C_CkHttpW.h> #include <C_CkHttpResponseW.h> void ChilkatSample(void) { BOOL success; HCkXmlW xml; const wchar_t *strXml; int responseStatusCode; HCkHttpW http; const wchar_t *endPoint; HCkHttpResponseW resp; HCkXmlW 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 = CkXmlW_Create(); success = CkXmlW_LoadXmlFile(xml,L"ukPostCodeSoap.xml"); if (success == FALSE) { wprintf(L"%s\n",CkXmlW_lastErrorText(xml)); CkXmlW_Dispose(xml); return; } strXml = CkXmlW_getXml(xml); http = CkHttpW_Create(); // We'll need to add this in the HTTP header: // SOAPAction: "http://www.webserviceX.NET/GetUKLocationByPostCode" CkHttpW_SetRequestHeader(http,L"SOAPAction",L"http://www.webserviceX.NET/GetUKLocationByPostCode"); // The endpoint for this soap service is: endPoint = L"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 = CkHttpResponseW_Create(); success = CkHttpW_HttpStr(http,L"POST",endPoint,strXml,L"utf-8",L"text/xml",resp); if (success == FALSE) { wprintf(L"%s\n",CkHttpW_lastErrorText(http)); CkXmlW_Dispose(xml); CkHttpW_Dispose(http); CkHttpResponseW_Dispose(resp); return; } responseStatusCode = CkHttpResponseW_getStatusCode(resp); // You may wish to verify that the responseStatusCode equals 200... wprintf(L"Response Status Code: %d\n",responseStatusCode); // You may examine the exact HTTP header sent with the POST like this: wprintf(L"LastHeader:\n"); wprintf(L"%s\n",CkHttpW_lastHeader(http)); // Examine the XML returned by the web service: wprintf(L"XML Response:\n"); xmlResp = CkXmlW_Create(); CkXmlW_LoadXml(xmlResp,CkHttpResponseW_bodyStr(resp)); wprintf(L"%s\n",CkXmlW_getXml(xmlResp)); // Use this online tool to generate parsing code from response XML: // Generate Parsing Code from XML CkXmlW_Dispose(xml); CkHttpW_Dispose(http); CkHttpResponseW_Dispose(resp); CkXmlW_Dispose(xmlResp); } |
