Golang奇怪的格式日期

Question

I have to convert a string date with this format:

Thu, 01 Nov 2018 14:20:34 +0700

.. into this format:

2018-11-01 14:20:34

I tried it with the following code:

dt_pub, err := time.Parse("RFC1123", Thu, 01 Nov 2018 14:20:34 +0700)
dt_pub.Format("2006-01-02 15:04:05")

But unfortunately, the result looks like this:

0001-01-01 00:00:00 +0000 UTC

Answer 1

See Go package time.

0001-01-01 00:00:00 +0000 UTC is the zero value for time.Time. The zero value is returned when a parsing error has occurred.

Check for errors. Use the time.RFC1123Z (RFC1123 with numeric zone) layout for parsing to match your input. For example,

package main

import (
    "fmt"
    "time"
)

func main() {
    dt_pub, err := time.Parse(time.RFC1123Z, "Thu, 01 Nov 2018 14:20:34 +0700")
    if err != nil {
        fmt.Println(err)
        return
    }
    fmt.Println(dt_pub)
    fmt.Println(dt_pub.Format("2006-01-02 15:04:05"))
}

Output:

2018-11-01 14:20:34 +0700 +0700
2018-11-01 14:20:34
