云端业务系统获取设备位置 API

业务系统调用 QueryDevicePropertyData 查询 IoT 设备的位置

业务系统通过QueryDevicePropertyData API 查询具体设备的位置信息CommonRequest request = new CommonRequest();request.setSysMethod(MethodType.POST);request.setSysDomain("iot.cn-shanghai.aliyuncs.com");request.setSysVersion("2018-01-20");request.setSysAction("QueryDevicePropertyData");request.putQueryParameter("RegionId", "cn-shanghai");request.putQueryParameter("StartTime", "1618330349204");request.putQueryParameter("Identifier", "GeoLocation");request.putQueryParameter("Asc", "0");request.putQueryParameter("EndTime", "1629330349204");request.putQueryParameter("PageSize", "10");request.putQueryParameter("IotInstanceId", "iot-068a03kg");request.putQueryParameter("ProductKey", "g7palBDnzmT");request.putQueryParameter("DeviceName", "dk003");CommonResponse response = client.getCommonResponse(request);
