date - 如何使用golang打印两个日期之间的具体日期？

Question

我正在从数据库中检索 start_date 和 end_date。通过 for 循环，我将打印之间的日期(星期一、星期二、...等等)。我也有同样的情况，我打印两个日期之间的日期，但我想如果我正在检索星期一的数据，那么它将显示接下来的星期一而不是所有天。如果我正在检索星期二的数据，那么它只显示星期二的日期我已经尝试了一个代码，但它会整天打印我将如何获得预期的输出

代码:-

func GetSchedule(c *gin.Context) {
response := ResponseControllerList{}
selected_day:= "Monday"
conditions := bson.M{"day":selected_day}
data, err := models.GetSchedulingListing(conditions) 
for i := range data {
    start_date := data[i].StartDate
    end_date := data[i].EndDate
    start_time := data[i].StartTime
    end_time := data[i].EndTime
    start_working_hours := time.Unix(start_time,0).Format("3:04PM")
    end_working_hours := time.Unix(end_time,0).Format("3:04PM")
    days := time.Unix(end_date,0).Sub(time.Unix(start_date,0)).Hours() / 24
    for i := 1; i <= int(days+1); i++ {
        // fmt.Println(i)
        // fmt.Println(start_date)
        fmt.Println(time.Unix(start_date,0).Format("Monday, 01-02-2006")+" "+ start_working_hours+" "+ end_working_hours)
        start_date = start_date + 86400
    }
}
dataCount, err := models.GetRecordsCount(config.ScheduleCollection, conditions)
if err != nil {
    response = ResponseControllerList{
        config.FailureCode,
        config.FailureFlag,
        config.FailureMsg,
        nil,
        nil,
    }
} else {
    response = ResponseControllerList{
        config.SuccessFlag,
        config.SuccessFlag,
        config.SuccessMsg,
        data[0],
        dataCount,
    }
}
GetResponseList(c, response)
}

查看我通过星期一的情况，但它在输出中返回所有日期:-

输出-

Tuesday, 05-01-2018 8:00AM 10:00AM
Wednesday, 05-02-2018 8:00AM 10:00AM
Thursday, 05-03-2018 8:00AM 10:00AM
Friday, 05-04-2018 8:00AM 10:00AM
Saturday, 05-05-2018 8:00AM 10:00AM
Sunday, 05-06-2018 8:00AM 10:00AM
..Soo on up to end date 

预期输出如果我给出条件 That only Monday 那么:-

Monday, 05-07-2018 8:00AM 10:00AM
...Next Monday date

如果我在星期二投降

Tuesday, 05-01-2018 8:00AM 10:00AM
... next Tuesday date

Answer 1

我可以给你一些关于如何实现目标的提示:

get the days of the week between two dates that satisfies a given predicadate?

按照这个代码片段，希望它能提供一些关于如何实现预期目标的线索。

这是更直接的: https://play.golang.org/p/-zQYNWtgHZ2

这有更多的设计决策: https://play.golang.org/p/qHlsCoQkSiQ

• 请注意您应该实现星期几像 func admitAllWeekDays 这样的过滤/选择。
• 另请注意，星期几的实现基于整数。

把答案放在一边，Slack，你需要的是稍微组织一下你的代码。我看到你比你提出的问题本身更挣扎。
