问题：soap协议 soap 访问 web service ,无法传递参数。
描述: asp.net web服务的代码如下：
[WebMethod]
public string AddCard(int guid, string key)
{
int m = guid;
return "OK!";
}
soap30 客户端的代码如下：
ISoapSerializerPtr Serializer;
ISoapReaderPtr Reader;
ISoapConnectorPtr Connector;
Connector.CreateInstance(__uuidof(HttpConnector30));
Connector.CreateInstance(__uuidof(HttpConnector30));
Connector->Property["EndPointURL"] = "http://172.25.16.65/vdo/Backend/Service1.asmx";
Connector->Connect();
// begin message
Connector->Property["SoapAction"] = "http://tempuri.org/AddCard";
Connector->BeginMessage();
// create serializer
Serializer.CreateInstance(__uuidof(SoapSerializer30));
// interface serializer
Serializer->Init(_variant_t((IUnknown*)Connector->InputStream));
// make soap packet
Serializer->StartEnvelope("","","");
Serializer->StartBody("");
Serializer->StartElement("AddCard","http://tempuri.org","NONE","SOAP");
Serializer->StartElement("guid","http://tempuri.org","NONE","SOAP");
Serializer->WriteString("55");
Serializer->EndElement();
Serializer->StartElement("key","http://tempuri.org","NONE","SOAP");
Serializer->WriteString("10254");
Serializer->EndElement();
Serializer->EndElement();
Serializer->EndBody();
Serializer->EndEnvelope();
// send message
Connector->EndMessage();
// recv response message
Reader.CreateInstance(__uuidof(SoapReader30));
// connect output stream
if(Connector->OutputStream)
Reader->Load(_variant_t((IUnknown*)Connector->OutputStream), "");
// printf result
if(Reader)
if(Reader->RpcResult)
if(strlen((const char *)Reader->RpcResult->text))
{
CString str = Reader->RpcResult->text;
//str.Format("%s",(const char *)Reader->RPCResult->text);
AfxMessageBox(str);
}
执行客户端时，可以调用服务端的AddCard方法，但是传近来的参数int guid, string key始终煤烟值，guid == 0 key == null,
搞不懂哪里出了问题。请各位指教！谢谢！
