javascript - Node JS session 错误 : express-session deprecated

Question

我的 Node js 文件中有以下内容

var express = require('express');
var util = require('./lib/utility');
var partials = require('express-partials');
var bodyParser = require('body-parser');

var session = require('express-session');

/* abstracted some code */

app.use(session({
  genid: function(req) {
    return genuuid(); // use UUIDs for session IDs
  },
  secret: 'keyboard cat'
}));

当我启动服务器时，我得到

express-session deprecated undefined resave option; provide resave option server.js
express-session deprecated undefined saveUninitialized option; provide saveUninitialized option server.js

我很难弄清楚什么是弃用的？我从 https://github.com/expressjs/session 复制了示例

当我尝试加载页面时，我得到:

ReferenceError: genuuid is not defined at app.use.session.genid

来自 express 4.0 , express-session with odd warning message

正如警告所说，默认值会发生变化，因此他们希望通过现在明确设置值来确保当默认值确实发生变化时(在不久的将来)，您不会遇到意外行为。

app.use(session({
    secret: cookie_secret,
    resave: true,
    saveUninitialized: true
}));
