英文:
Get Day, Month, and Year from Time in Go Language
问题
我有一个像这样的对象：
type searchObj struct {
symbol string
dataType string
fromDate time.Time
toDate time.Time
}
我想从fromDate和toDate中解析出日、月和年。我该如何做到这一点？是否有更好的类型可以使用，比如(Date)，因为我不需要时间部分？
所以我想能够传递一个日期，像这样02/19/2016，并能够得到data.Day = 19，date.Month = 02，date.Year = 2016。
我尝试了这样的代码：
search.fromDate.Date.Month
search.fromDate.Date.Day
search.fromDate.Date.Year
这是我目前用来创建searchObj的示例代码：
time.Date(2009, time.November, 10, 23, 0, 0, 0, time.UTC)
我是Go的新手，谢谢你的帮助！
英文:
I have an object like this:
type searchObj struct {
symbol string
dataType string
fromDate time.Time
toDate time.Time
}
I want to be able to parse out the day, month, and year from the fromDate and the toDate. How can I do this? Is there a better type to use like (Date) because I do not need the time piece of it?
so I want to be able to pass a date like this 02/19/2016 and be able to get data.Day = 19, date.Month = 02, date.Year = 2016.
I was trying something like this:
search.fromDate.Date.Month
search.fromDate.Date.Day
search.fromDate.Date.Year
This is an example of what I am currently using to create the searchObj:
time.Date(2009, time.November, 10, 23, 0, 0, 0, time.UTC)
I am new to Go and thank you for the help!

你所寻找的所有方法都存在于time.Time类型中。你可以这样做：
year := fromDate.Year()
month := fromDate.Month()
day := fromDate.Day()
编辑：
我想使用time.Date可能更简洁，像这样：
year, month, day := fromDate.Date()
英文:
All the methods you're looking for exist on the time.Time type. You can just do;
year := fromDate.Year()
month := fromDate.Month()
day := fromDate.Day()
EDIT:
I suppose it would be more concise to use time.Date like so;
year, month, day := fromDate.Date()

time类型还有一个Date()方法，可以在一次调用中返回时间的年、月和日。
英文:
The time type also has Date() method which returns the year, month and day of the time in single call.

使用接受的方法，如果你需要月份的数字，你可以将Month对象简单地转换为int，因为它是一个枚举类型：
year, month, day := time.Now().Date()
log.Printf("%v-%v-%v", year, int(month), day)
英文:
With the accepted method, if you need the month number you can simply cast the Month object to int since it's an enum:
year, month, day := time.Now().Date()
log.Printf("%v-%v-%v", year, int(month), day)
