Golang 获取时间格式化

package main

func main(){
    now := time.Now()
    fmt.Printf("%T %v",now,now)
    fmt.Println()
    fmt.Printf("年：%v 、",now.Year())
    fmt.Printf("月：%v 、",int(now.Month()))

    fmt.Printf("时：%v 、",now.Hour())
    fmt.Printf("分：%v 、",now.Minute())
    fmt.Printf("秒：%v ",now.Second())
    fmt.Println()
    //方式一：格式化时间
    dateStr := fmt.Sprintf("%d-%d-%d %d:%d:%d",now.Year(),int(now.Month()),
                            now.Day(),now.Hour(),now.Minute(),now.Second())
    //2020-3-18 19:25:7

    //2020-03-18 19:25:07
    fmt.Printf("%s",dateStr1)
    fmt.Println()
    //格式化方式二：
    //2020/03/18 19:30:29
    fmt.Printf(now.Format("2006/01/02 15:04:05"))
