cookie插件怎么用取cookie的方法 _生活百科

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-cookiesnpm install vue-cookies --save3.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//例如：that.$cookies.remove("CHOOSE","/",'.xxx.com')-检查某个 cookie name是否存在
this.$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 array5.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.$cookies.config(60 * 60 * 24 * 30,'');// window objectwindow.$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)：
Unitfull nameyyearmmonthddayhhourminminutessecond

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 paththis.$cookies.set("use_path_argument","value","1d","/app");// set domainthis.$cookies.set("use_path_argument","value",null, null, "domain.com");// set securethis.$cookies.set("use_path_argument","value",null, null, null,true);

**遇到的问题1、this.$cookies.get(‘CHOOSEJWTTOKEN’)为什么取不到值？
重点排除一下：如果cookie中设置了HttpOnly ，那么通过js脚本将无法读取cookie信息。（这样能有效的防止XSS攻击，窃取cookie内容，但即便这样，也不建议将重要的信息存入cookie 。）
