Express 项目环境搭建 -- 4. 解析 cookie

Express 自身也不解析 cookie，毕竟 cookie 这种东西也就浏览器才用，Express 官方包甚至连 cookie 处理的中间件都给剥离出来，以第三方模块的方式引入

const express = require("express");
const cookieParser = require("cookie-parser");
app.use(cookieParser());

使用方法如下：

app.get('/', function (req, res) {
  // Cookies that have not been signed
  console.log('Cookies: ', req.cookies)

  // Cookies that have been signed
  console.log('Signed Cookies: ', req.signedCookies)
})
