完整示例代码参考SetCookie

Server

cnpm i -g express-generator pm2

express SetCookieServer

# cd SetCookieServer
cnpm i

cnpm i --save express-cors

vim app.js

// 省略了未修改的代码
var app = express();

var cors = require('express-cors');  
app.use(cors({
  allowedOrigins: [
    'http://localhost:8000'
  ],
}));
// 省略了未修改的代码

关于CORS更多介绍参考MDN - HTTP访问控制（CORS）

vim routes/index.js

var express = require('express');
var router = express.Router();

router.post('/login', function(req, res, next) {
  res.cookie('ZHCMD_SESS', 'cookie-from-node', { domain: 'localhost', expires: new Date(Date.now() + 1000000000), httpOnly: true })
  res.send({ msg: 'success' });
});

router.get('/list', function(req, res, next) {
  res.send({ msg: JSON.stringify(req.cookies) });
});

module.exports = router;
