Golang实现输入两个日期时间转换为周时间

golang

最近使用Go语言在写一个数据后台系统，要求输入两个日期时间，出现按周查询的数据，网上找了找，没有发现用 Go 语言实现的博客文章，就自己写了，开始觉得很简单，写着写着发现我的方法好麻烦，算了 也写好了，如果有兴趣的小伙伴可以换另一种方法试试（我还没有试试呢）——循环所有日期 得出星期几，把周一和周日按一组分。这里只展示我已经实现的方法。

import ( "fmt" "log" "time" )var WeekDayMap = map[string]int64{ "Monday":1, "Tuesday":2, "Wednesday": 3, "Thursday":4, "Friday":5, "Saturday":6, "Sunday":7, }// 获取输入的两个日期分别是星期几 func GetWeekDay(startime, endtim string) (int64, int64) { startday, _ := time.Parse("2006-01-02", startime) endday, _ := time.Parse("2006-01-02", endtim) staweek_int := startday.Weekday().String() endweek_int := endday.Weekday().String() return WeekDayMap[staweek_int], WeekDayMap[endweek_int] }// 字符串转时间戳 func StringToTimeStamp(strTime string) int64 { timeLayout := "2006-01-02" //timeLayout := "2006-01-02 15:04:05" loc, _ := time.LoadLocation("Local") the_time, err := time.ParseInLocation(timeLayout, strTime, loc) if err != nil { log.Println("StringToTimeStamp出现异常：", err) } unix_time := the_time.Unix() return unix_time }// 时间戳转 字符串 func TimeStampToString(timeStp int64) string { //转化所需模板 //timeLayout := "2006-01-02 15:04:05" timeLayout := "2006-01-02" //进行格式化 datetime := time.Unix(timeStp, 0).Format(timeLayout) return datetime }// 时间转化为周日期列表 func ChangeToWeek(startime, endtim string) []map[string]string { staweek_int, endweek_int := GetWeekDay(startime, endtim) // 获取时间戳 start_stamp := StringToTimeStamp(startime) end_stamp := StringToTimeStamp(endtim) fmt.Println("start_stamp==",start_stamp,"end_stamp==", end_stamp) var week_list = make([]map[string]string, 0) if (end_stamp-start_stamp)/604800 <= 1 && endweek_int-staweek_int >= 0 { if end_stamp-start_stamp < 604800 && endweek_int-staweek_int > 0 { one_map := map[string]string{} mon_one := TimeStampToString(start_stamp - (staweek_int-1)*86400) sun_one := TimeStampToString(start_stamp + (7-staweek_int)*86400) one_map["mon"] = mon_one one_map["sun"] = sun_one week_list = append(week_list, one_map) return week_list } one_map := map[string]string{} mon_one := TimeStampToString(start_stamp - (staweek_int-1)*86400) sun_one := TimeStampToString(start_stamp + (7-staweek_int)*86400) one_map["mon"] = mon_one one_map["sun"] = sun_one week_list = append(week_list, one_map) tow_map := map[string]string{} mon_tow := TimeStampToString(end_stamp - (endweek_int-1)*86400) sun_tow := TimeStampToString(end_stamp + (7-endweek_int)*86400) tow_map["mon"] = mon_tow tow_map["sun"] = sun_tow week_list = append(week_list, tow_map) return week_list } week_n := (end_stamp - start_stamp) / 604800 one_map := map[string]string{} mon_one := TimeStampToString(start_stamp - (staweek_int-1)*86400) sun_one := TimeStampToString(start_stamp + (7-staweek_int)*86400) one_map["mon"] = mon_one one_map["sun"] = sun_one week_list = append(week_list, one_map) for i := 1; i <= int(week_n); i++ { week_map := map[string]string{} mon_day := TimeStampToString(start_stamp - (staweek_int-1)*86400 + int64(i)*604800) sun_day := TimeStampToString(start_stamp + (7-staweek_int)*86400 + int64(i)*604800) week_map["mon"] = mon_day week_map["sun"] = sun_day week_list = append(week_list, week_map) } if endweek_int-staweek_int >= 0 { return week_list } tow_map := map[string]string{} mon_tow := TimeStampToString(end_stamp - (endweek_int-1)*86400) sun_tow := TimeStampToString(end_stamp + (7-endweek_int)*86400) tow_map["mon"] = mon_tow tow_map["sun"] = sun_tow week_list = append(week_list, tow_map) return week_list}func main(){ fmt.Println(ChangeToWeek("2020-01-01","2020-01-28"))} // 结果： //start_stamp== 1577808000end_stamp== 1580140800 //[ map[mon:2019-12-30 sun:2020-01-05] //map[mon:2020-01-06 sun:2020-01-12] //map[mon:2020-01-13 sun:2020-01-19] //map[mon:2020-01-20 sun:2020-01-26] //map[mon:2020-01-27 sun:2020-02-02] ]
