常用的web工具集合

auth

权限组件，对路径进行检查，并返回匹配的角色数组

使用示例

import Auth from 'luck7-webtools/auth'

const config = { // config也可以是Promise
  whiteList: ['/login'],
  roles: {
    user: /^\/admin\/news[/]?/,
    mannage: /^\/admin[/]?/,
    super: /^\/admin\/setting[/]?/
  }
}
// const config = ajax('role', {}).then(res => {
//   return {
//     whiteList: ['/login'],
//     roles: res.roles
//   }
// })

const auth = new Auth(config)

export default auth

跟vue-router结合的检查方法示例

import auth from './auth'
/**
 * 检查是不是拥有某个权限
 * @param {array} roles 要查询的角色，如['mannage','user']
 * @return {true|vueRoute} 如果拥有所有权限，返回true，否则返回不符合的权限要跳到的路由
 */
function check (roles) {
  if (roles === undefined) return true
  const noLogin = window.sessionStorage.getItem('userid') === null
  if (roles.indexOf('mannage') > -1) {
    // 判断是不是管理员
    const isAdmin = window.sessionStorage.getItem('role') === 'admin'
    return !noLogin && isAdmin ? true : {name: 'denied'}
  } else {
    // 判断是不是已经登陆
    return noLogin ? {path: '/login'} : true
  }
}
const checkAuth = function (path, callback) {
  auth.getAuth(path).then(role => {
    if (role === true) {
      callback(true)
    } else {
      callback(check(role))
    }
  })
}
router.beforeEach((to, from, next) => {
  checkAuth(to.fullPath, next)
})

bom

常用浏览器自带方法的集合

import {openWindow} from 'luck7-webtools/bom'
// openWindow(url, title, w, h)
openWindow('http://www.google.com', 'google', 500, 400)

cache

可以根据请求参数缓存函数执行结果

import cache from 'luck7-webtools/cache'
function test (i) {
  return i + Math.random()
}
class Demo1 {
  constructor (config) {
    this.config = config
  }
  test (i) {
    return new Promise((resolve, reject) => {
      setTimeout(() => resolve(test(i + 5)), this.config.delay)
    })
  }
}
var a1 = new Demo1({delay: 1000})
var b1 = cache(test, 3000)
var a2 = cache(a1.test.bind(a1), 5000)

a1.test(3).then(res => console.log(res))
// 8.442179866889822
setTimeout(() => a1.test(3).then(res => console.log(res)), 1000)
// 8.745571849291068
console.log(b1(3))
// 3.2365098725515358
setTimeout(() => console.log(b1(3)), 1000)
// 3.2365098725515358
setTimeout(() => console.log(b1(3)), 3500)
// 3.4376061338653397
a2(3).then(res => console.log(res))
// 8.207727726819655
setTimeout(() => a2(3).then(res => console.log(res)), 3500)
// 8.207727726819655

cookie

对cookie管理的封装

import CookieManager from 'luck7-webtools/cookie'

const cookie = new CookieManager()

cookie.set('key1', 'vaule1')
cookie.set(
  'key2', // key
  'vaule2', // value
  { // options, 可不填
    expires: '3s', // eg: '1d5h33m4s' 可不填，默认为浏览器生命周期
    path: '/',
    // domain: ''
  }
)
console.log('1', cookie.get('key2'))
// 1 vaule2

setTimeout(() => console.log('2', cookie.get('key2')), 3500)
// 2 undefined

console.log('3', cookie.get('key1'))
// 3 vaule1
cookie.del('key1')
console.log('4', cookie.get('key1'))
// 4 undefined

dom

encoder

字符编码相关的处理类

import {Byte, Utf8, Base64} from 'luck7-webtools/encoder'

var a1 = Byte.parse('hello 中国 Ã')
// [104, 101, 108, 108, 111, 32, 228, 184, 173, 229, 155, 189, 32, 195, 131]
var b1 = Byte.stringfy(a1)
// 'hello 中国 Ã'
var a2 = Utf8.parse('hello 中国 Ã')
// 'hello 中国 Ã'
var b2 = Utf8.stringfy(a2)
// 'hello 中国 Ã'
var a3 = Base64.parse('hello 中国 Ã')
// aGVsbG8g5Lit5Zu9IMOD
var b3 = Base64.stringfy(a3)
// 'hello 中国 Ã'

import Encrypt from 'luck7-webtools/encrypt'
const data = '12345678'
