不明白錯誤

Question

我正在嘗試爲我的node.js/express.js/react.js應用程序添加身份驗證。

我的目錄結構如下：

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

我這兩行添加到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我看到我以前沒有見過的新的消息：

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

然後在瀏覽器中，當我連接到我得到這個錯誤。如果刪除了上面兩行從server.js程序運行罰款：

在瀏覽器中，我看到了異常：

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 

如果抱怨我不能從錯誤告訴它不能找到sessions.js，或者如果它未能找到npm要求。我沒有安裝express-session，我看到它在package.json所以不知道......

這可能會或可能不會幫助任何人。

最初的問題是我沒有通過護照會議。這個固定的問題：

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 

然後我有另一個問題，我有以下注釋掉版本的代碼，因爲沒有祕密，導致了錯誤。一旦我真的輸入了一個字符串密碼，問題就消失了

'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()];
