下附源码
引入 vue-cookies
npm install vue-cookies --save
// require
var Vue = require('vue')
Vue.use(require('vue-cookies'))
// es2015 module
import Vue from 'vue'
import VueCookies from 'vue-cookies'
Vue.use(VueCookies)
$cookies.config() 设置默认值
$cookies.config(expireTimes, path)
expireTimes 默认1d
path 默认'/'。 注意：// 哈希模式下：域名/projectName/#/aaaa 默认为 '/projectName'。 域名/projectName#/aaaa 默认为 '/'。确认 #号前面是否有'/'。
$cookies.set()
$cookies.set(key, value[, expireTimes[, path[, domain[, secure]]]])
- key: cookie名
注意 $cookies key names Cannot be set to ['expires', 'max-age', 'path', 'domain', 'secure']- value: cookie值
vue-cookie会自动帮你把对象转为json if (value && value.constructor === Object ){value = JSON.stringify(value)}- expireTimes: cookie有效时间，默认时间为1d
可以为到期时间点(expire=) [Date]，也可以为有效时间段单位s(max-age=)[Number]，传入Infinity||-1被认该cookie永久有效，传入0 会被判断为false导致取默认值，传入非-1 的负数会立即删除该cookie。传入String类型但又不会被正则匹配的('0'、'abc'、'Session')则关闭浏览器的时候销毁cookie(Expire/Max-Age=Session)，效果类似Session。- path: cookie所在目录，默认 '/' 根目录
设置path: '/projectName'指定项目名下'/projectName'使用- domain: cookie所在的域，默认为请求地址
- secure: Secure属性是说如果一个cookie被设置了Secure=true，那么这个cookie只能用https协议发送给服务器，用http协议不发送。
$cookies.get('key')
$cookies.get(key) // return value
$cookies.remove('key')
$cookies.remove(key [, path [, domain]]) // return false or true , warning： next version return this； use isKey(key) return true/false,please
是否有key cookie
$cookies.isKey(key) // return true or false
列出所有cookie
$cookies.keys() // return ['key', 'key', ......]
