CurrencyConvertor - How use gSOAP and WebServices - Part 2 Doing the first WS client.

Introduction

This is the second of two articles where I explain building a web service client from wsdl file. With Part One, I explained how to get the class from the wsdl file to be used in VC++ 6. In Part Two, I will show you how to use the classes generated with gSOAP in Part One.

Using the code

Usually in the file soap*****************SoapProxy.h we can find the class definition of generic WS. In this case, soapCurrencyConvertorSoapProxy.h, I have already included it in Part One.

//soapCurrencyConvertorSoapProxy.h

#ifndef soapCurrencyConvertorSoap_H
#define soapCurrencyConvertorSoap_H
#include "soapH.h"
class CurrencyConvertorSoap
{   public:
    struct soap *soap;
    const char *endpoint;
    CurrencyConvertorSoap()
    { soap = soap_new(); endpoint = 
        "http://www.webservicex.net/CurrencyConvertor.asmx";
        if (soap && !soap->namespaces) 
        { static const struct Namespace namespaces[] = 
{
    {
 "SOAP-ENV", "http://schemas.xmlsoap.org/soap/envelope/", 
        "http://www.w3.org/*/soap-envelope", NULL},
    {

    {NULL, NULL, NULL, NULL}

    soap->namespaces = namespaces; } };

        soap_end(soap); soap_done(soap); soap_del(soap); } };
