【mdapi.ReqQryMulticastInstrument】 CTP返回“无此功能”？

[AresFung]

md.ReqQryMulticastInstrument(ApiStructure.QryMulticastInstrumentField(), md.request_id)

OnRspError:
requestID: 0
RspInfoField<ErrorID(77),ErrorMsg(CTP:无此功能)>
True

Or should I get all listing instruments from tradeApi?

你这参数错误，不能直接传入ApiStructure.QryMulticastInstrumentField()，要实例化的
