用前先安装SOAP安装包。

做以下引用：

#import "msxml4.dll"
#import "MSSOAP30.DLL" exclude("IStream", "ISequentialStream", "_LARGE_INTEGER","_ULARGE_INTEGER", "tagSTATSTG", "_FILETIME")
using namespace MSXML2;
using namespace MSSOAPLib30;

调用方式：

CString InvokeWebService(LPCTSTR fun,LPCTSTR param[],LPCTSTR values[])
{

ISoapSerializerPtr Serializer;
ISoapReaderPtr Reader;
ISoapConnectorPtr Connector;

if(FAILED(Connector.CreateInstance(__uuidof(HttpConnector30))))    //创建对象
    {
  printf("失败");
    }

Connector->Property["EndPointURL"] = (_variant_t)Config->endPointURL; //wsdl路径
Connector->Connect();
Connector->Property["SoapAction"] = (_variant_t)Config->soapAction;

Connector->BeginMessage();
Serializer.CreateInstance(__uuidof(SoapSerializer30));

Serializer->Init(_variant_t((IUnknown*)Connector->InputStream));

// Build the SOAP Message.

Serializer->StartEnvelope("Soap","","");

Serializer->StartBody("");

Serializer->StartElement(fun,(_bstr_t)Config->soapAction,"","Soap"); //函数处理
for(int pi=0;pi<sizeof(param)/4;pi++)
{
  Serializer->StartElement((_bstr_t)param[pi],"","","Soap");
  Serializer->WriteString((_bstr_t)values[pi]);          //参数处理
  Serializer->EndElement();
}
Serializer->EndElement();

Serializer->EndBody();

Serializer->EndEnvelope();

Connector->EndMessage();

Reader.CreateInstance(__uuidof(SoapReader30));

Reader->Load(_variant_t((IUnknown*)Connector->OutputStream),""); //加载返回数据

//-------------------------------------------------------------------------------------//
MSXML2::IXMLDOMDocumentPtr     pDoc;
    MSXML2::IXMLDOMElementPtr      xmlRoot;
    HRESULT     hr     =     pDoc.CreateInstance(__uuidof(MSXML2::DOMDocument30));
    pDoc->loadXML(Reader->GetRpcResult()->xml);

    CString temp="";

//如返回列表，可用循环
if(pDoc->childNodes->Getitem(0)->childNodes->Getlength()>0)
temp=(char*)pDoc->childNodes->Getitem(0)->childNodes->Getitem(0)->Gettext();
return temp;
}
