我使用以下内容使用 express 设置 cookie。

res.cookie('test', 'yes', { 
    expires: new Date(Date.now() + 365*2*24*60*60*1000), 
    httpOnly: true 
});

我正在使用中间件来尝试读取 cookie：

app.use(express.cookieParser());

var cookie_id = req.cookies.test;

问题是 cookie_id 是未定义的，它会是“是”

  app.use(express.cookieParser());
});

express.cookieParser() 之前 需要使用app.router；中间件按顺序运行，这意味着它甚至cookieParser()在您的路线执行之前永远不会到达。

尝试这个：

  app.set('views', __dirname + '/views');
  app.set('view engine', 'jade');
  app.use(express.bodyParser());
  app.use(express.methodOverride());
  app.use(express.cookieParser());
  app.use(app.router);
  app.use(express.static(__dirname + '/public'));

大多数中间件（如 cookieParser）不再与 Express 捆绑，必须单独安装。

安装 cookie 解析器：

npm install cookie-parser

用法

var express      = require('express')
var cookieParser = require('cookie-parser')

var app = express()
app.use(cookieParser())

我通过app.use(express.cookieParser());在app.router.
