框架介绍

另一个知名的是： asaskevich/govalidator

thedevsaddam/govalidator 借鉴 Laravel ，简单易用

表单规则

govalidator.MapData{}

MapData{} 是 map[string][]string 的自定义类型。

rules := govalidator.MapData{
    "name":             []string{"required", "alpha_num", "between:3,20"},
    "email":            []string{"required", "min:4", "max:30", "email"},
    "password":         []string{"required", "min:6"},
    "password_confirm": []string{"required"},
}

错误消息

messages := govalidator.MapData{
    "name": []string{
        "required:用户名不能为空",
        "alpha_num:格式错误，只允许数字和英文",
        "between:用户名长度需在 3~20 之间",
    },
    "email": []string{
        "required:邮箱不能为空",
        "min:Email 长度需大于 4",
        "max:Email 长度需小于 30",
        "email:Email 格式不正确，请提供有效的邮箱地址",
    },
    "password": []string{
        "required:密码为必填项",
        "min:长度需大于 6",
    },
    "password_confirm": []string{
        "required:确认密码框为必填项",
    },
}

配置选项

govalidator.Options{}

type Options struct {
    Data            interface{} // Data represents structure for JSON body
    Request         *http.Request
    RequiredDefault bool    // RequiredDefault represents if all the fields are by default required or not
    Rules           MapData // Rules represents rules for form-data/x-url-encoded/query params data
    Messages        MapData // Messages represents custom/localize message for rules
    TagIdentifier   string  // TagIdentifier represents struct tag identifier, e.g: json or validate etc
    FormSize        int64   //Form represents the multipart forom data max memory size in bytes
}

opts := govalidator.Options{
    Data:          &_user,
    Rules:         rules,
    Messages:      messages,
    TagIdentifier: "valid", // struct 标签标识符
}

开始认证

errs := govalidator.New(opts).ValidateStruct()

验证函数命名规则

Validate{表单名称}Form ，例如注册表单就是： ValidateRegistrationForm
