golang判断当前时间是第几周的方法

Go语言中使用import关键字导入包，包的名字使用双引号（""）包裹起来。

golang判断当前时间是第几周：

func main() {        l, _ := time.LoadLocation("Asia/Shanghai")        startTime,_ := time.ParseInLocation("2006-01-02", "2018-12-22", l)        endTime,_ := time.ParseInLocation("2006-01-02", "2019-05-17", l)        datas := GroupByWeekDate(startTime, endTime)        for _, d := range datas {                fmt.Println(d)        }}//判断时间是当年的第几周func WeekByDate(t time.Time) string {        yearDay := t.YearDay()        yearFirstDay := t.AddDate(0, 0, -yearDay+1)        firstDayInWeek := int(yearFirstDay.Weekday())        //今年第一周有几天        firstWeekDays := 1        if firstDayInWeek != 0 {                firstWeekDays = 7 - firstDayInWeek + 1        }        var week int        if yearDay <= firstWeekDays {                week =  1        } else {                week = (yearDay-firstWeekDays)/7 + 2        }        return fmt.Sprintf("%d第%d周", t.Year(), week)}type WeekDate struct {        WeekTh    string        StartTime time.Time        EndTime   time.Time}// 将开始时间和结束时间分割为周为单位func GroupByWeekDate(startTime, endTime time.Time) []WeekDate {        weekDate := make([]WeekDate, 0)        diffDuration := endTime.Sub(startTime)        days := int(math.Ceil(float64(diffDuration / (time.Hour * 24))))+1        currentWeekDate := WeekDate{}        currentWeekDate.WeekTh = WeekByDate(endTime)        currentWeekDate.EndTime = endTime        currentWeekDay := int(endTime.Weekday())        if currentWeekDay == 0 {                currentWeekDay = 7        }        currentWeekDate.StartTime = endTime.AddDate(0, 0, -currentWeekDay+1)        nextWeekEndTime := currentWeekDate.StartTime        weekDate = append(weekDate, currentWeekDate)        for i := 0; i < (days-currentWeekDay)/7; i++ {                weekData := WeekDate{}                weekData.EndTime = nextWeekEndTime                weekData.StartTime = nextWeekEndTime.AddDate(0, 0, -7)                weekData.WeekTh = WeekByDate(weekData.StartTime)                nextWeekEndTime = weekData.StartTime                weekDate = append(weekDate, weekData)        }        if lastDays := (days - currentWeekDay) % 7; lastDays > 0 {                lastData := WeekDate{}                lastData.EndTime = nextWeekEndTime                lastData.StartTime = nextWeekEndTime.AddDate(0, 0, - lastDays)                lastData.WeekTh = WeekByDate(lastData.StartTime)                weekDate = append(weekDate, lastData)        }        return weekDate}

结果：
