vue資源庫中有個插件很好用vue-cookies,專門用於在vue中處理瀏覽器的cookie操作，vue-cookies沒有依賴關係，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。
安裝vue-cookies
npm install vue-cookies --save
引入vue-cookies
安裝完畢後，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)
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
設置cookie過期時間
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')
單個name設置
//不寫過期時間，默認爲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.$cookies.set("user_session","25j_7Sl6xDq2Kc3ym0fmrSSk2xV2XkUkX","1D")
// 以秒爲單位，設置1天過去
this.$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);
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.$cookies.set("token","GH1.1.1689020474.1484362313","60s"); // 60秒後過去
this.$cookies.set("token","GH1.1.1689020474.1484362313","30MIN"); // 30分鐘後過去
this.$cookies.set("token","GH1.1.1689020474.1484362313","24d"); // 24天后過期
this.$cookies.set("token","GH1.1.1689020474.1484362313","4m"); // 4個月後過期
this.$cookies.set("token","GH1.1.1689020474.1484362313","16h"); // 16小時後過期
this.$cookies.set("token","GH1.1.1689020474.1484362313","3y"); // 3年後過期
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);
