在Go中将YYYYMMDD转换为Unix时间[重复]

Question

This question already has an answer here:

• Parsing date string in Go 6 answers

I have a form input where I figure it would be easiest for the user to simply insert date as YYYYMMDD, so I was wondering how I should go about converting that user input to Unix time?

import "time"

func SomeFormPOST(w http.ResponseWriter, r *http.Request) {
  err := r.ParseForm()
  // err handling
  date := r.FormValue("date")
  unixDate := date.DOWHAT.Unix()
}

I think maybe I need to use t, _ = time.Parse(...) but not haven't been able to figure it out..

You are correct, you can use time.Parse, where the first argument is the layout of the second, the second being the value you want to parse.

That means that if you know that the value you want to parse has this YYYYMMDD format you can use the reference time to construct the layout argument. And since the reference time is specified in the docs as Mon Jan 2 15:04:05 -0700 MST 2006 your layout should look like this: 20060102.

layout := "20060102"
t, err := time.Parse(layout, date)
if err != nil {
   panic(err)
}
fmt.Println(t)
