Input Validation Vulnerabilities Dominate MITRE's 2024 CWE Top 25 List
MITRE's 2024 CWE Top 25 highlights critical software vulnerabilities like XSS, SQL Injection, and CSRF, reflecting shifts due to a refined ranking methodology.
check-data
Advanced tools
npm install check-data --save
let Validator = require('check-data')
let { error, data, $, ... } = Validator(data, options, constructor)
data
* - 输入验证数据,类型参考type选项
options
* - 数据验证表达式,类型参考type选项
export
Objcte - 自定义数据导出方法,使用验证后的数据创建新的数据结构,通过方法中的this和第一个函数参数提取验证数据(可选)
error
String - 验证失败时返回的错误信息,包含错误的具体位置,仅用于验证失败时的错误定位
msg
String - 验证失败时返回的错误信息,相对于error对用户更加友好,可用于客户端显示
data
Objcte - 经过验证、处理后导出数据(带空值过滤,用于剔除对象中的空数组、空字符串、undefind、null等无效数据)
${name}
Objcte - 由export对象中构造方法导出的数据,命名与export中函数名一致(带空值过滤)
type
* - 表示数据类型,可选类型有String、Number、Object、 Array、Date、Boolean、"MongoId"、"MobilePhone"(扩展类型用字符串表示)
name
String - 自定义参数名称,用于错误返回值中替换默认参数名
default
* - 默认赋值
value
* - 直接通过表达式赋值,类似于default选项,区别是不管值是否为空都将使用该值覆盖(优先级低于default,目前没有发现同时使用的应用场景)
allowNull
Boolean - 是否允许为空,默认为true
and
Array、Function - 声明依赖的参数名数组,支持数组和函数两种表达式,函数表达式用于声明指定值的依赖关系。要求依赖的所有参数都不能为空
or
Array、Function - 与and相似,区别是只要求依赖的其中一个参数不为空即可
method
Function - 参数自定义转换方法,非空值时执行
minLength
Number - 限制字符串最小长度
maxLength
Number - 限制字符串最大长度
reg
RegExp - 正则表达式验证
in
Array - 匹配多个可选值中的一个
min
Number - 限制最小值
max
Number - 限制最大值
in
Array - 匹配多个可选值中的一个
to
* - 类型转换,仅支持Boolean值
仅支持类型验证
仅支持类型验证
仅支持类型验证
验证mongodb中的ObjectId
验证手机号
验证Email
使用Validator.use(typename, options)
let { error, data } = Validator(["a", "b", "c"], [String])
