Installation

  npm install check-data --save

使用方法

let Validator = require('check-data')

let { error, data } = Validator(data, options, customize)

输入

  • 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

  • customize Objcte - 自定义数据导出对象(可选)

  • customize.$ Function - 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,this和函数第一个参数指向已验证数据

输出

  • error String - 验证失败时返回的错误信息,包含错误的具体位置信息,仅供开发者调试使用

  • 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)

  • msg String - 验证失败后返回的错误信息,相对于error而言,msg对用户更加友好,可直接在客户端显示

公共选项

  • 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

不同数据类型的私有选项

String
  • 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

Number
  • 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

Array
  • minLength Number - 限制字符串最小长度

  • maxLength Number - 限制字符串最大长度

Object

仅支持类型验证

Date、Boolean

仅支持类型验证

扩展类型

'MongoId'

验证mongodb中的ObjectId

'MobilePhone'

验证手机号

'Email'

验证Email

自定义扩展

使用Validator.use(typename, options)

数组验证

  let { error, data } = Validator(["a", "b", "c"], [String])

  let { error, data } = Validator([{
     "a":1,
     "b":"bibi",
     "c":"test"
  },{
     "a":1,
     "b":"bibi",
     "c":"test"
  }], [{
     a: Number,
     b: String,
     c: String
  }])

对象验证

  let { error, data } = Validator({
     "a": 1,
     "b": "xx",
     "c": [1,32,34],
     "d": 666
  }, {
     "a": Number,
     "b": String,
     "c": [String],
     "d": Number
  })

and验证

  let { error, data } = Validator({
     "username": "莉莉",
     "addressee": "嘟嘟",
  }, {
     "username": {
        "type": String,
        // 使用数组表达式
        "and": ["addressee", "address"],
     },
     "addressee": {
        "type": String,
        "allowNull": true
     },
     "address": {
        "type": String,
        "allowNull": true,
        // 使用函数表达式,表示特定值的依赖关系
        and(value){
           if (value === 1) {
              return ["addressee", "address"]
           } else if (value === 2) {
              return ["username", "xx"]
           }
        },
     }
  })

or验证

  let { error, data } = Validator({
     "username": "莉莉",
     "addressee": "嘟嘟",
  }, {
     "username": {
        "type": String,
        "or": ["addressee", "address"]
     },
     "addressee": {
        "type": String,
        "allowNull": true
     },
     "address": {
        "type": String,
        "allowNull": true
     }
  })

扩展类型验证

  let { error, data } = Validator({
     "id": "5968d3b4956fe04299ea5c18",
     "mobilePhone": "18555555555",
  }, {
     "id": "MongoId",
     "mobilePhone": "MobilePhone"
  })
  

自定义类型

  Validator.use('Int', {
     type({ data }) {
        if (Number.isInteger(data)) {
           return { data }
        } else {
           return { err: '必须为Int类型' }
        }
     },
  })
