      //计算卡路里
      rv.calorie = rp.amount * rv.recordItem.calorie

      return rv;
    })
  }

  /*

      rv.recordItem = RecordItemModel.getById(rp.keepId)

      rv.calorie = rp.amount * rv.recordItem.calorie

      return rv;
    })
  }

  calculateKeepInfo(records: RecordVO[]):KeepInfo {
    let info = new KeepInfo()
    //如果RecordVO对象数组为空，不执行操作，直接返回KeepInfo对象
    if (!records || records.length <= 0) {
      return info
    }
    //当日总任务个数
    info.task = records.length

    records.forEach(rv => {
      //如果完成任务个数 = 当然任务个数，表示当天所有任务都已经完成
      if(rv.amount !== 0 && rv.successAmount === rv.amount) {
        info.successTask += 1
      }
      info.expend += rv.calorie
      info.day = rv.createTime
    })
    //如果总任务个数=已完成任务个数，将是否完成当天任务属性赋值为true
    if (info.task === info.successTask && info.task !== 0) {
      info.isSuccess = true
    }

    Logger.debug(info.task + '/' + info.successTask + ',任务时间:' + info.day + ',总任务/已完成任务')

    return info

  }
}

let keepService = new KeepService();

export default keepService as KeepService;

代码在将RecordPO对象转换成RecordVO那里出现了Object literal must correspond to some explicitly declared class or interface (arkts-no-untyped-obj-literals)

Answer 1

后面发现只要把构造函数去掉就好了
