关于Delphi7调用webservice接口问题
我用Delphi7调用接口，地址：http://219.159.20.164/hisjk/Service.asmx?WSDL，我先新建一个Application，然后在基础上新建了Delphi中的WebServices中的WSDL Importer，加载出来函数有：function yhklxgjk(const sHospitalCode: WideString; const sUser: WideString; const sOldPWD: WideString; const sNewPWD: WideString; const sMsg: WideString): WideString; stdcall;

我在Application的Button控件双击事件中写如下代码：

procedure TForm1.Button1Click(Sender: TObject);
var
BackMsg :WideString;

RIO :THTTPRIO;
RemoteObj :ServiceSoap;
Ret :WideString;
begin

RIO := THTTPRIO.Create(nil);
RIO.WSDLLocation := 'http://219.159.20.164/hisjk/Service.asmx?WSDL';
RemoteObj := rio as ServiceSoap;
Ret := remoteObj.yhklxgjk('1033','033','8888','6666',BackMsg);
showmessage('Ret='+Ret);
end;
参数中的值都是正确的（是人家给的）！

可运行后双击总是会报如下错误：
Project Project1.exe raised exception class ESOAPHTTPException with message 'Unable to retrieve the URL endpoint for Service/Port 'Service'/'' from WSDL 'http://219.159.20.164/hisjk/Service.asmx?WSDL''.Process stopped.Use Step or Run to continue.

不知何解，有劳指教！

把webservice，写到URL里
rio.url
