框架校验组件内置了40+左右常用的校验规则。GoFrame框架校验组件内置了数十项常用的校验规则，校验组件是开发者最频繁使用的框架核心组件之一。

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


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。以下示例代码中我们均采用常用的结构体校验的方式，结构体属性中的`v`标签标识`validation`的缩写，用于设置该属性的校验规格。

修饰规则

修饰规则本身没有任何的校验逻辑，而是修改后续功能规则的实现逻辑。

`ci`

格式： ci
说明：字段值比较在默认情况下为区分大小写严格匹配比较，通过ci(Case Insensitive)修饰规则，可以设置后续需要比较值的规则字段为不区分大小写。如：same, different, in, not-in等。
示例：
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。

		ctx = context.Background()
		req = BizReq{

Account:

"gf",

} ) if err := g.Validator().CheckStruct(ctx, req

	Password:  "Goframe.org", // Diff from Password2, but because of "ci", rule check passed
			Password2: "goframe.org",
		}
	)
	if err := g.Validator().Data(req).Run(ctx); err != nil {
		fmt.Println(err)
	}

	//

Output: // The Name field is required }

required-if

output: }

bail

Note
需要特别注意：如果参数校验存在多条校验规则，并且规则中存在`required`规则和`bail`修饰规则一起使用时，那么建议将`required`校验规则放置于所有规则之前，否则`bail`校验规则的特性（校验失败即停止后续校验）有可能会引起后续规则的`required*`规则不生效。

格式：bail
说明：只要后续的多个校验中有一个规则校验失败则停止校验并立即返回校验结果。
注意：在框架的HTTP Server组件中，如果采用规范路由注册方式，在其自动校验特性中将会自动开启bail修饰规则，开发者无需在Req对象中显式设置bail。
示例：
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

	// Outputoutput:

required-unless

 Account value `gf` length must be between 6 and 16
}

`foreach`

格式：foreach
说明：用于数组参数，将待检验的参数作为数组遍历，并将后一个校验规则应用于数组中的每一项。
版本：框架版本>=v2.2.0
示例：
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
