如何将接口类型传递给over过程参数？

type
    Hello_PortType = interface(ISoapInvokable)
      ['{243CBD89-8766-F19D-38DF-427D7A02EAEE}']
        function GetDeneme(s: string): string;
      end;

SoapCall(Hello_PortType , 'http://localhost:8080/wsdl/ITDeneme');

那么如何使用带有saopcall方法变量的TypeInfo？

function TLib.SoapCall(Intf: Variant; Addr: string): ISoapInvokable;
var
  RIO: THTTPRIO;
begin

  InvRegistry.RegisterInterface(TypeInfo(Intf), 'urn:DenemeIntf-IDeneme', ''); //-- type info doesn't work with variant
  InvRegistry.RegisterDefaultSOAPAction(TypeInfo(Intf), 'GetDeneme');

  Result := nil;
  if Addr = '' then
    exit();

  RIO := THTTPRIO.Create(nil);
  try
    Result := RIO as ISoapInvokable;
    RIO.URL := Addr;
  finally
    if (Result = nil) then
      RIO.Free;
  end;
end;
