日期

举个例子 只用看 Addtime

type Article struct {
    Model

    TagID int `json:"tag_id" gorm:"index"`
    Tag   Tag `json:"tag"`

    Title      string `json:"title"`
    Desc       string `json:"desc"`
    Content    string `json:"content"`
    CreatedBy  string `json:"created_by"`
    ModifiedBy string `json:"modified_by"`
    State      int    `json:"state"`
    Addtime    string `json:"add_time" gorm:"column:add_time;index"`
}




func GetArticles(pageNum int, pageSize int, maps interface{}) (articles []Article) {
    db.Preload("Tag").Where(maps).Offset(pageNum).Limit(pageSize).Find(&articles)

    for i, v := range articles {
        // res_time, _ := time.Parse("2006-01-02T15:04:05Z07:00", strconv.Itoa(v.Model.CreatedOn*1000))
        // v.Addtime = res_time.Format("2006-01-02 15:04:05")
        // v.Addtime = (res_time)
        fmt.Println("ddddd---", i, v)
        // res_time := time.Unix(int64(v.Model.CreatedOn), 0)
        res_time, _ := time.Parse("2006-01-02T15:04:05Z07:00", v.Addtime)
        articles[i].Addtime = res_time.Format("2006-01-02 15:04:05")
    }

    // fmt.Print("sssss---", articles)

    return articles
}

日期定义 gorm

    Addtime    string `json:"add_time" gorm:"column:add_time;index"`

数据中格式转换

    res_time, _ := time.Parse("2006-01-02T15:04:05Z07:00", v.Addtime)
    articles[i].Addtime = res_time.Format("2006-01-02 15:04:05")

如果存储的是int类型

    res_time := time.Unix(int64(v.Model.CreatedOn), 0)
    articles[i].Addtime = res_time.Format("2006-01-02 15:04:05")

日期例子

func main() {
    new := time.Now()
    fmt.Println(new)
    fmt.Println(new.Unix())
    fmt.Println(new.UnixNano())
    fmt.Println(time.Unix(new.Unix(), 0))
    // 定时器
    // aa := time.Tick(time.Second)
    // for t := range aa {
    //  fmt.Println(t.Format("2006-01-02 03:04:05"))
    // }
    // dd, _ := time.Parse("2006-01-02 03:04:05", "2022-01-03 03:04:05")
    dd, _ := time.Parse("2006-01-02 03:04:05", "1666670424407555900")

    fmt.Println(dd)
}
