An answer for 2017 ..
2017年的答案..
const cookieParser = require('cookie-parser');
const express = require('express');
const app = express();
app.use(cookieParser());
to get a cookie from an incoming request ..
从传入的请求中获取 cookie ..
let cookie = req.cookies['cookiename'];
to set a response cookie (this cookie will be sent on all future incoming requests until deletion or expiration) ..
设置响应 cookie（此 cookie 将在所有未来传入请求中发送，直到删除或到期）..
res.cookie('cookiename', 'cookievalue', {
maxAge: 86400 * 1000, // 24 hours
httpOnly: true, // http only, prevents JavaScript cookie access
secure: true // cookie must be sent over https / ssl
});
to delete a response cookie ..
删除响应 cookie ..
res.cookie('cookiename', 'cookievalue', {
maxAge: 0
});
