使用vue-cookies操作cookie

1.前言

在vue中如果想要操作cookie，除了使用之前我們自己封裝好的操作cookie的方法之外，我們還可以使用vue-cookies插件，這是一個簡單的Vue.js插件，專門用於在vue中處理瀏覽器的cookie操作，vue-cookies沒有依賴關系，它可以獨立存在，對vuejs友好。本篇博文就來介紹如何使用vue-cookies插件。

2.安裝vue-cookies

npm install vue-cookies --save

3.引入vue-cookies

安裝完畢后，我們需要在vue項目中明確引入vue-cookies。

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

4.API

• 設置全局配置，設置cookie過期時間和url

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

• 設置一個cookie

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

• 獲取一個cookie

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

• 刪除一個cookie

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

• 檢查某個 cookie name是否存在

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

• 獲取所有 cookie name，以數組形式返回

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

5.設置cookie過期時間

5.1全局設置

// 30天后過期
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單個name設置

//不寫過期時間，默認為1天過期
this.$cookies.set("user_session","25j_7Sl6xDq2Kc3ym0fmrSSk2xV2XkUkX")

// 1天過期，忽略大小寫
this.$cookies.set("user_session","25j_7Sl6xDq2Kc3ym0fmrSSk2xV2XkUkX","1d")
this.$cookies.set("user_session","25j_7Sl6xDq2Kc3ym0fmrSSk2xV2XkUkX","1D")

// 以秒為單位，設置1天過去
this.$cookies.set("user_session","25j_7Sl6xDq2Kc3ym0fmrSSk2xV2XkUkX",60 * 60 * 24)

// 填寫Date對象，明確指定過期時間
this.$cookies.set("user_session","25j_7Sl6xDq2Kc3ym0fmrSSk2xV2XkUkX", new Date(2017, 03, 12))

// 填寫一個時間字符串，指定過期時間
this.$cookies.set("user_session","25j_7Sl6xDq2Kc3ym0fmrSSk2xV2XkUkX", "Sat, 13 Mar 2017 12:25:57 GMT")

//瀏覽器會話結束時過期
this.$cookies.set("default_unit_second","input_value","0");
 
//永不過期
this.$cookies.set("default_unit_second","input_value",-1); 

5.3字符串單位形式設置

設置過期時間，輸入字符串類型(字符均忽略大小寫)：

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秒后過去

this.$cookies.set("token","GH1.1.1689020474.1484362313","30MIN");  // 30分鍾后過去

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

this.$cookies.set("token","GH1.1.1689020474.1484362313","4m");  // 4個月后過期

this.$cookies.set("token","GH1.1.1689020474.1484362313","16h");  // 16小時后過期

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

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);
