1.用户model


type UserBasic struct {
	gorm.Model
	Name          string
	PassWord      string
	Phone         string `valid:"matches(^1[3-9]{1}\\d{9}$)"`
	Email         string `valid:"email"`
	Avatar        string //头像
	Identity      string
	ClientIp      string
	ClientPort    string
	Salt          string
	LoginTime     time.Time
	HeartbeatTime time.Time
	LoginOutTime  time.Time `gorm:"column:login_out_time" json:"login_out_time"`
	IsLogout      bool
	DeviceInfo    string
}

2.gorm引入

golang学习之gorm(一):Gorm介绍_golang gorm_浅弋、璃鱼的博客-CSDN博客

1)连接数据库db, err := gorm.Open(mysql.Open() )

2）创建或者更新一张和指定strcut结构一样的表db.AutoMigrate(&models.UserBasic{})

3)增db.Create(user)

4)删db.Delete(&product, 1)

5)改db.Model(user).Update("PassWord", "1234")

6)查db.First(user, 1)，查主键为1的user
