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!

 

四、特殊使用（在Cookie中存对象）

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'))
