前端数据缓存定时失效方案：LocalStorage与js-cookie实战

export function setLocalStorageAndTime (key, value) {
 window.localStorage.setItem(key, JSON.stringify({ data: value, time: new Date().getTime() }))
}

 // 有数据再进行存储
   setLocalStorageAndTime('XXX', {name: 'XXX'})

// 判断是否返回为null或者失效
getLocalStorageAndTime('XXX', 86400000)

export function getLocalStorageAndTime (key, exp = 86400000) {
 // 获取数据
 let data = window.localStorage.getItem(key)
 if (!data) return null
 let dataObj = JSON.parse(data)
 // 与过期时间比较
 if (new Date().getTime() - dataObj.time > exp) {
  // 过期删除返回null
  removeLocalStorage(key)
  console.log('信息已过期')
  return null
 } else {
  return dataObj.data
 }
}

Cookies.set('name', 'value', { expires: 7 }); // 7 天后失效

let seconds = 10;
let expires = new Date(new Date() * 1 + seconds * 1000);
Cookies.set('username', 'tanggaowei', { expires: expires }); // 10 秒后失效

import Cookies from 'js-cookie'

/*
* 设置cookies
* */
export function getCookies (key) {
 return Cookies.get(key)
}
/*
* 设置Cookies
* */
export function setCookies (key, value, expiresTime) {
 let seconds = expiresTime
 let expires = new Date(new Date() * 1 + seconds * 1000)
 return Cookies.set(key, value, { expires: expires })
}
/*
* 移除Cookies
* */
export function removeCookies (key) {
 return Cookies.remove(key)
}
