不明白错误

Question

我正在尝试为我的node.js/express.js/react.js应用程序添加身份验证。

我的目录结构如下：

application 
    server.js 
    www 
    js 
     app.js 
     sessions.js 

我这两行添加到server.js

var express = require('express'), 
    app = express(), 
    path = require('path'), 
    http = require('http').Server(app), 
    io = req 

let sessions = require('./www/js/sessions'); 
app.use(sessions); 

我跑node server.js我看到我以前没有见过的新的消息：

$ node server.js 
express-session deprecated req.secret; provide secret option www/js/sessions.js:16:22 

然后在浏览器中，当我连接到我得到这个错误。如果删除了上面两行从server.js程序运行罚款：

在浏览器中，我看到了异常：

TypeError: passport.initialize is not a function 
    at module.exports.passport (/home/idf/Documents/js/react-trader/www/js/sessions.js:18:56) 
    at Layer.handle [as handle_request] (/home/idf/Documents/js/react-trader/node_modules/express/lib/router/layer.js:95:5)

    at /home/idf/Documents/js/react-trader/node_modules/express/lib/router/index.js:280:7 

如果抱怨我不能从错误告诉它不能找到sessions.js，或者如果它未能找到npm要求。我没有安装express-session，我看到它在package.json所以不知道......

这可能会或可能不会帮助任何人。

最初的问题是我没有通过护照会议。这个固定的问题：

let usersService = require('./service/users'); 
let bodyParser = require('./middleware/bodyParser'); 
let passport = require('./config/passport'); 
let sessions = require('./middleware/sessions')(passport); // was missing parameter passport 

然后我有另一个问题，我有以下注释掉版本的代码，因为没有秘密，导致了错误。一旦我真的输入了一个字符串密码，问题就消失了

'use strict'; 

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

let config = { 
    //secret: process.env.SESSION_SECRET, 
    secret: 'keyboard cat', 
    saveUninitialized: false, 
    resave: false 
}; 

if (process.env.REDIS_URL) { 
    const RedisStore = require('connect-redis')(session); 
    config.store = new RedisStore({ url: process.env.REDIS_URL }); 
} 

let expressSession = session(config); 

module.exports = passport => [expressSession, passport.initialize(), passport.session()];
