import moment from "moment"

//日期类型

    month: 'month',
    lastMonth: 'lastMonth',
}

//开始时间
let start = ''
//结束时间
let end = ''

let handleDateType = {
    //今日

        start = moment().format("YYYY-MM-DD")
        end = moment().format("YYYY-MM-DD")
        return {start , end}
    })(),
    //昨日

        end = moment().subtract(1, 'days').format('YYYY-MM-DD');
        return {start , end}
    })(),
    //这周
