将日期从DD-MON-YY转换为YYYYMMDD

Question

In GoLang, how should I convert date from DD-MON-YY to YYYYMMDD format?

My input is: 9-Nov-17
Expected output is: 20171109

But when I do below:

t, err := time.Parse("20060102", "9-Nov-17")

Golang returns error:

Error: parsing time "9-Nov-17" as "20060102": cannot parse "v-17" as "2006"

Please help.

Answer 1

You have to parse the time in the current format and then format it into the expected format using Format function

Check the answer below

package main

import (
    "fmt"
    "time"
)

func main() {
    // Parse a time value from a string in dd-Mon-yy format.
    t, _ := time.Parse("2-Jan-06", "9-Nov-17")
    //Format and print time in yyyymmdd format
    fmt.Println(t.Format("20060102"))
}
