框架校验组件内置了数十项常用的校验规则。

Note

校验规则涉及到联合校验的场景时，规则中关联的参数名称会自动按照不区分大小写且忽略特殊字符的形式进行智能匹配。

required

  • 格式: required
  • 说明：必需参数，除了支持常见的字符串，也支持Slice/Map类型。

  • 示例：姓名字段Name为必需参数必需不能为空。

    Code Block
    languagego
    func ExampleValidatorExample_Rule_Required() {
	type BizReq struct {
		IdID   uint   `v:"required"`
		Name string `v:"required"`
	}
	var (
		ctx = context.Background()
		req = BizReq{
			IdID: 1,
		}
	)
	if err := g.Validator().CheckStructData(req).Run(ctx, req); err != nil {
		fmt.PrintlnPrint(err)
	}

	// Output:
	// The Name field is required
}


required-if

  • 格式: required-if:field,value,...
  • 说明：必需参数(当任意所给定字段值与所给值相等时，即：当field字段的值为value时，当前验证字段为必须参数)。

  • 示例：当Gender字段为1时WifeName字段必须不为空， 当Gender字段为2时HusbandName字段必须不为空。

    Code Block
    languagego
    func ExampleValidatorExample_Rule_RequiredIf()  {
	type BizReq struct {
		IdID          uint   `v:"required" dc:"Your IdID"`
		Name        string `v:"required" dc:"Your name"`
		Gender      uint   `v:"in:0,1,2" dc:"0:Secret;1:Male;2:Female"`

			Gender: 1,
		}
	)
	if err := g.Validator().Data(req).CheckStructRun(ctx, req); err != nil {
		fmt.Println(err)
	}

	// Output:
	// The WifeName field is required
}


required-unless

  • 格式: required-unless:field,value,...
  • 说明：必需参数(当所给定字段值与所给值都不相等时，即：当field字段的值不为value时，当前验证字段为必须参数)。

  • 示例：当Gender不等于0且Gender不等于2时，WifeName必须不为空；当Id不等于0且Gender不等于2时，HusbandName必须不为空。
