Question

我正在尝试向我的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

我将这两行添加到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我看到一条我以前没见过的新消息：

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

然后在我连接到浏览器时出现此错误。如果我从server.js删除上面的两行，程序运行正常：

在浏览器中，我看到异常：

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

我无法从错误中判断出它是否抱怨找不到sessions.js，或者是否找不到npm要求。我确实安装了express-session，我在package.json中看到了，所以不确定......

这可能会或可能不会帮助其他人。

最初的问题是我没有将护照传递给会议。这解决了这个问题：

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，因为我在下面的代码中注释了注释版本，并且因为没有秘密而导致错误。一旦我真正输入字符串秘密，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()];

不明白错误
