vc6.0 调用webservice的问题，结果总是返回soap:Client
我用vc6.0调用webservice，结果总是返回soap:Client





以下是代码
ISoapSerializerPtr Serializer; 
ISoapReaderPtr Reader; 
ISoapConnectorPtr Connector; 

// Connect to the service 
HRESULT hr;
hr= CoInitialize(NULL);//初始化com环境
if(FAILED(hr))
{
MessageBox("初始化COM失败");
}

hr =Connector.CreateInstance(__uuidof(HttpConnector30));
if(FAILED(hr))
{
//创建com对象出错，一般是因为没有安装com
MessageBox("创建HttpConnector FAILED");
}

Connector->Property["EndPointURL"] = "http://10.246.0.38:8888/DESEncryptService.asmx";//"http://localhost/WebService1/Service1.asmx"; 

hr=Connector->Connect();//和服务器连接 
if(FAILED(hr))
{
AfxMessageBox("连接WEBSERVICE FAILED");
}

// Begin message 
CString cstr="";
cstr.Format("%s",method);
AfxMessageBox(cstr);
Connector->Property["SoapAction"] = "http://cmis.sinopec.com/erp/DesEncrypt/DESEncryptString";//"http://xin.org/getIP";
Connector->BeginMessage(); 

Serializer.CreateInstance(__uuidof(SoapSerializer30)); 

// 将serializer连接到connector的输入字符串 
Serializer->Init(_variant_t((IUnknown*)Connector->InputStream)); 

// 创建SOAP消息 
Serializer->StartEnvelope("Soap","",""); 
Serializer->StartBody(""); 
Serializer->StartElement("DESEncryptString","http://cmis.sinopec.com/erp/DesEncrypt/DESEncryptString","","Soap");//命名空间必须有

for(int i=0;i<argv_len;i++)
{
Serializer->StartElement(args[i],"","","Soap");
Serializer->WriteString(argv[i]);
Serializer->EndElement();
}
Serializer->EndElement();
Serializer->EndBody();
Serializer->EndEnvelope(); 

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

// 读取响应 
Reader.CreateInstance(__uuidof(SoapReader30)); 

// 将reader联接到connector的输出字符串 
Reader->Load(_variant_t((IUnknown*)Connector->OutputStream), ""); 

//cout<<(const char *)Reader->RpcResult->text); 
//const char * str = (const char *)Reader->RpcResult->firstChild->text; 

//printf("Answer: %s\n",(const char*)Reader->RpcResult->xml);
const char* returnValue=(const char*)Reader->RpcResult->text;
MessageBox((const char*)Reader->RpcResult->text);
MessageBox((const char*)Reader->RpcResult->xml);

[解决办法]
我也是，等解决
