输出在RFC3339中的时间与MySQL格式一样

在荷兰,我们大多使用YYYY-MM-DD HH:MM:SS。如何在Go中格式化?我插入的所有内容(即使按照标准)都会给出奇怪的数字。

这是我的代码(p.CreatedNanoSeconds int64对象):

package main

import (
    "database/sql"
    "fmt"
    _ "github.com/go-sql-driver/mysql"
    "log"
    "time"
)

const createdFormat = "2010-01-01 20:01:00" //"Jan 2, 2006 at 3:04pm (MST)"

type Post struct {
    Id      int64
    Created int64
    Title   string
    Body    string
}

func main() {
    // Establish database connection
    dsn := "root@tcp(127.0.0.1:3306)/testdb"
    con, err := sql.Open("mysql", dsn)
    if err != nil {
        log.Println("Couldn't connect to databse:", err)
    } else {
        log.Println("DB Connection established")
    }
    defer con.Close()

    // Try to get something
    row := con.QueryRow("SELECT * FROM posts LIMIT 1")
    p := new(Post)
    err = row.Scan(&p.Id, &p.Created, &p.Title, &p.Body)

    if err != nil {
        log.Println("Failed to fetch Post")
    }
    fmt.Println(p)
    fmt.Println(time.Unix(0, p.Created).Format(createdFormat))
}

我可以直接time.Unix(0, p.Created).Year()等,但这不是很干净,并且是一致的烦恼。

上面有两个错误。对于您需要输出特殊日期/时间的格式,以及time.Unix的参数是另一种方式(playground

const createdFormat = "2006-01-02 15:04:05" //"Jan 2, 2006 at 3:04pm (MST)"

fmt.Println(time.Unix(1391878657, 0).Format(createdFormat))
