C++ 使用soap调用webservice问题

arden1019 2006-11-14 04:05:27

有一个webservice，我需要访问此接口，下面是它的wsdl:

- <wsdl:operation name="retrieveUserUsageQuota" parameterOrder="subId">
<wsdl:input message="impl:retrieveUserUsageQuotaRequest" name="retrieveUserUsageQuotaRequest" />
<wsdl:output message="impl:retrieveUserUsageQuotaResponse" name="retrieveUserUsageQuotaResponse" />
</wsdl:operation>

我从soap help文档中找到了一个c++的例子：
#include "stdafx.h"
#include < stdio.h>

#import "msxml3.dll"
using namespace MSXML2;

#import "C:\Program Files\Common Files\MSSoap\Binaries\mssoap1.dll" \
exclude("IStream", "ISequentialStream", "_LARGE_INTEGER", \
"_ULARGE_INTEGER", "tagSTATSTG", "_FILETIME")
using namespace MSSOAPLib;

void Add()
{

ISoapSerializerPtr Serializer;
ISoapReaderPtr Reader;
ISoapConnectorPtr Connector;

// Connect to the service
Connector.CreateInstance(__uuidof(HttpConnector));
Connector->Property["EndPointURL"] = "http://localhost/DocSample2/DocSample2.asp";
Connector->Connect();

// Begin message
Connector->Property["SoapAction"] = "uri:AddNumbers";
Connector->BeginMessage();

// Create the SoapSerializer
Serializer.CreateInstance(__uuidof(SoapSerializer));

// Connect the serializer to the input stream of the connector
Serializer->Init(_variant_t((IUnknown*)Connector->InputStream));

// Build the SOAP Message
Serializer->startEnvelope("","","");
Serializer->startBody("");
Serializer->startElement("Add","uri:Calc","","m");
Serializer->startElement("A","","","");
Serializer->writeString("5");
Serializer->endElement();
Serializer->startElement("B","","","");
Serializer->writeString("10");
Serializer->endElement();
Serializer->endElement();
Serializer->endBody();
Serializer->endEnvelope();

// Send the message to the web service
Connector->EndMessage();

// Let us read the response
Reader.CreateInstance(__uuidof(SoapReader));

// Connect the reader to the output stream of the connector
Reader->Load(_variant_t((IUnknown*)Connector->OutputStream), "");

// Display the result
printf("Answer: %s\n", (const char*)Reader->RPCResult->text);

}

int main()
{
CoInitialize(NULL);
Add();
CoUninitialize();

return 0;

}
但是，不清楚soap以及wsdl等等规范，希望那位老大可以帮我改好上面的访问例子。实在是急事，没时间详细看soap和wsdl，等这个demo做出来我再细细研究，谢谢各位了。
或者帮我介绍一下，使用soap访问这个webservice时候需要如何写message...
