NodeJS 会话有问题

Question

我正在尝试为基于 nodejs 的网络应用程序实现登录功能。

const express = require('express');
const app = express();
const route = express.router;
const sessions = require("client-sessions");

app.use(sessions({
  coockieName:  'SNsession',
  secret: '0GBlJZ9EKBt2Zbi2flRPvztczCewBxXK' // set this to a long random string!
}));

const user = 'john';

app.get('/login', function (req, res){
  req.sessions.user = user;
});

const port = process.env.PORT || 5000;
app.listen(port, function () {
  console.log("listening on " + port);
});

app.get('/', function (req, res) {
  res.send('index');
});

我希望看到与我在 Mozilla Hack 的博客上看到的完全相同的结果也发生在我的计算机上。 博文： https://hacks.mozilla.org/2012/12/using-secure-client-side-sessions-to-build-simple-and-scalable-node-js-applications-a-node-js-holiday-season-part-3/

尽管如此，我得到了这个：

TypeError: Cannot set property 'user' of undefined

    at Layer.handle [as handle_request] (c:\node\node_modules\express\lib\router\layer.js:95:5)

我一直在尝试解决这个问题好几个小时，但我还没有看到它起作用。

我已经复制并粘贴了博客上的代码，即使不修改它们，我也无法让它工作。 请帮忙:(

Answer 1

替换

 req.sessions.user = user;

有

 req.session.user = user;

从会话中删除最后一个 's'
