VC调用Webservice(本文为原创,转载清注明出外)

用C++调用axis2的WebService,用Sproxy.exe生成Ｃ＋＋代码总是不成功．只好采用MS原始的ＣＯＭ接口.

1.首先初始化连接：

// 初始化连接
CComQIPtr<ISoapConnector> CWebServices::CreateHttpConnector(CComBSTR webUrl)
{
    HRESULT hr;
    CComQIPtr<ISoapConnector> connector;
    connector.CoCreateInstance(__uuidof(HttpConnector30));
    if (connector){    
        connector->Property["EndPointURL"] = CComVariant(webUrl);    
        hr = connector->Connect();
        if (SUCCEEDED(hr)){
            connector->Property["SoapAction"] = CComVariant("http://localhost/");
            return connector;
        }
    }
    else {
        CUtils::WriteLog(true,_T("您的机器没有安装SoapToolkit30,请下载安装!"));
    }
    return CComQIPtr<ISoapConnector>();    
}

2.发送SOAP

 

************************************************************************/
/*  得到Soap序列化                                                                    */
/************************************************************************/
CComQIPtr<ISoapSerializer> CWebServices::GetSoapSerializer(CComQIPtr<ISoapConnector> connector)
{
    CComQIPtr<ISoapSerializer> serializer; 
    if (connector)    {
        if (SUCCEEDED(connector->BeginMessage()))
        {
            serializer.CoCreateInstance(__uuidof(SoapSerializer30));
            if (serializer){
                serializer->Init(_variant_t((IUnknown*)connector->InputStream));
                return serializer;
            }
        } 
    }
    return CComQIPtr<ISoapSerializer>();
}

 

3. 读取response

//返回读取器
CComQIPtr<ISoapReader> CWebServices::GetSoapReader(CComQIPtr<ISoapConnector> connector)
{
    CComQIPtr<ISoapReader> reader; 
    if (SUCCEEDED(reader.CoCreateInstance(__uuidof(SoapReader30))))
    {
        VARIANT_BOOL _hr;
        _hr = reader->Load(_variant_t((IUnknown*)connector->OutputStream), _bstr_t(""));
        if (_hr == VARIANT_TRUE)
            return reader;
    }
    return CComQIPtr<ISoapReader>();
}

调用过程只要通过ISoapSerializer接口把SOAP消息拼装发送就可以了．

（假如调用setCenEAIBatchMessage方法，有一个XML参数）

CComQIPtr<ISoapConnector> pConnector = CreateHttpConnector(m_url);
    CComQIPtr<ISoapSerializer> pSerializer  = GetSoapSerializer(pConnector);
        if (pSerializer){
            pSerializer->StartEnvelope("SOAP","","");
            pSerializer->StartBody("");

            pSerializer->StartElement("setCenEAIBatchMessage",_bstr_t(m_nameSpace),"","");
            pSerializer->StartElement("xml",_bstr_t(m_nameSpace),"","");
            pSerializer->WriteString(_bstr_t(paramter));
            pSerializer->EndElement();
            pSerializer->EndElement();
            pSerializer->EndBody();
            pSerializer->EndEnvelope();
            pConnector->EndMessage();
            }
