使用vue-cookies操作cookie

1.前言

在vue中如果想要操作cookie，除了使用之前我们自己封装好的操作cookie的方法之外，我们还可以使用vue-cookies插件，这是一个简单的Vue.js插件，专门用于在vue中处理浏览器的cookie操作，vue-cookies没有依赖关系，它可以独立存在，对vuejs友好。本篇博文就来介绍如何使用vue-cookies插件。

2.安装vue-cookies

npm install vue-cookies --save

3.引入vue-cookies

安装完毕后，我们需要在vue项目中明确引入vue-cookies。

import Vue from 'vue'
import VueCookies from 'vue-cookies'
Vue.use(VueCookies)

4.API

• 设置全局配置，设置cookie过期时间和url

this.$cookies.config(expireTimes[,path])  // default: expireTimes = 1d , path=/

• 设置一个cookie

this.$cookies.set(keyName, value[, expireTimes[, path[, domain[, secure]]]])   //return this

• 获取一个cookie

this.$cookies.get(keyName)       // return value                             

• 删除一个cookie

this.$cookies.remove(keyName [, path [, domain]])   // return this

• 检查某个 cookie name是否存在

this.$cookies.isKey(keyName)        // return false or true

• 获取所有 cookie name，以数组形式返回

this.$cookies.keys()  // return a array

5.设置cookie过期时间

5.1全局设置

// 30天后过期
this.$cookies.config('30d')

this.$cookies.config(new Date(2019,03,13).toUTCString())

this.$cookies.config(60 * 60 * 24 * 30,'');

// window object
window.$cookies.config('30d')

5.2单个name设置

//不写过期时间，默认为1天过期
this.$cookies.set("user_session","25j_7Sl6xDq2Kc3ym0fmrSSk2xV2XkUkX")

// 1天过期，忽略大小写
this.$cookies.set("user_session","25j_7Sl6xDq2Kc3ym0fmrSSk2xV2XkUkX","1d")
this.$cookies.set("user_session","25j_7Sl6xDq2Kc3ym0fmrSSk2xV2XkUkX","1D")

// 以秒为单位，设置1天过去
this.$cookies.set("user_session","25j_7Sl6xDq2Kc3ym0fmrSSk2xV2XkUkX",60 * 60 * 24)

// 填写Date对象，明确指定过期时间
this.$cookies.set("user_session","25j_7Sl6xDq2Kc3ym0fmrSSk2xV2XkUkX", new Date(2017, 03, 12))

// 填写一个时间字符串，指定过期时间
this.$cookies.set("user_session","25j_7Sl6xDq2Kc3ym0fmrSSk2xV2XkUkX", "Sat, 13 Mar 2017 12:25:57 GMT")

//浏览器会话结束时过期
this.$cookies.set("default_unit_second","input_value","0");
 
//永不过期
this.$cookies.set("default_unit_second","input_value",-1); 

5.3字符串单位形式设置

设置过期时间，输入字符串类型(字符均忽略大小写)：

Unit	full name
y	year
m	month
d	day
h	hour
min	minute
s	second

this.$cookies.set("token","GH1.1.1689020474.1484362313","60s");  // 60秒后过去

this.$cookies.set("token","GH1.1.1689020474.1484362313","30MIN");  // 30分钟后过去

this.$cookies.set("token","GH1.1.1689020474.1484362313","24d");  // 24天后过期

this.$cookies.set("token","GH1.1.1689020474.1484362313","4m");  // 4个月后过期

this.$cookies.set("token","GH1.1.1689020474.1484362313","16h");  // 16小时后过期

this.$cookies.set("token","GH1.1.1689020474.1484362313","3y");  // 3年后过期

6.其他操作

// set path
this.$cookies.set("use_path_argument","value","1d","/app");  

// set domain
this.$cookies.set("use_path_argument","value",null, null, "domain.com");  

// set secure
this.$cookies.set("use_path_argument","value",null, null, null,true);
