验证器

// 模型验证器包括2个方面： 1. 使用规则验证输入的json 2. 验证调用common.Bind(c, self)后填充的数据
// 用户验证json结构体

Bio string `form:"bio" json:"bio" binding:"max=1024"`
Image string `form:"image" json:"image" binding:"omitempty,url"`
} `json:"user"`
userModel UserModel `json:"-"`
}
// 用户验证内置方法
func (self *UserModelValidator) Bind(c *gin.Context) error {
