//为什么在路由id为1和2时 返回的状态码是 301 Moved Permanently 而id在3和之后的则正常

type User struct {

    Id       int

    Username string

}

func (User) TabkeName() string {

    return "user"

}

func GetUserTest(id int) (User, error) {

    var user User

    err := dao.Db.Where("id = ?", id).First(&user).Error

    return user, err

}
