Cookie的使用（js-cookie插件）-蒲公英云

Cookie的使用（js-cookie插件）

一、安装

npm install js-cookie --save

二、引用

import Cookies from 'js-cookie'

三、一般使用

1.存到Cookie去

// Create a cookie, valid across the entire site:  
Cookies.set('name', 'value');  
// Create a cookie that expires 7 days from now, valid across the entire site:  
Cookies.set('name', 'value', { expires: 7 });  
// Create an expiring cookie, valid to the path of the current page:  
Cookies.set('name', 'value', { expires: 7, path: '' });

2.在Cookie中取出

// Read cookie:  
Cookies.get('name'); // => 'value'  
Cookies.get('nothing'); // => undefined  
// Read all visible cookies:  
Cookies.get(); // => { name: 'value' }

3.删除

// Delete cookie:  
Cookies.remove('name');  
// Delete a cookie valid to the path of the current page:  
Cookies.set('name', 'value', { path: '' });  
Cookies.remove('name'); // fail!  
Cookies.remove('name', { path: '' }); // removed!

跟一般使用不同的是，从Cookie中取出的时候，要从字符串转换成json格式：

const user = {  
name: 'lia',  
age: 18}  
Cookies.set('user', user)const liaUser = JSON.parse(Cookies.get('user'))  
// Create a cookie, valid across the entire site:  
Cookies.set('name', 'value');  
// Create a cookie that expires 7 days from now, valid across the entire site:  
Cookies.set('name', 'value', { expires: 7 });  
// Create an expiring cookie, valid to the path of the current page:  
Cookies.set('name', 'value', { expires: 7, path: '' });

如下：自己封装util

auth.js

import Cookies from 'js-cookie'
const TokenKey = 'Admin-Token'
export function getToken() {
  return Cookies.get(TokenKey)
}
export function setToken(token) {
  return Cookies.set(TokenKey, token)
}
export function removeToken() {
  return Cookies.remove(TokenKey)
}
