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'))
