javascript - Node.js 重启后保持 Session

Question

我正在尝试获取 session 以在 Express v4 中存储护照 session ，但在服务器重新启动后它不会持续存在。我已经在使用 connect-mongo 所以我不清楚为什么它目前没有持续存在。

db.js

module.exports = function(app, config) {
    var mongoose = require('mongoose'),
    Schema = mongoose.Schema,
    session = require('express-session'),
    MongoStore = require('connect-mongo')(session),
    fs = require('fs');

    mongoose.connect(config.db);

    mongoose.connection.on('error', console.error.bind(console, 'connection error:'));
    mongoose.connection.once('open', function callback() {
        console.info('Database Connected!');
    });

    var sessionStore = new MongoStore({mongooseConnection: mongoose.connection});
    module.exports = sessionStore;
};

express.js

module.exports = function (app, config, passport, dbConnect) {
    /* #Flash messaging and sessions ------------------------------------------------- */
    app.use(cookieParser('secretStrings'));
    app.use(session({
        secret: 'secretStrings',
        resave: true,
        saveUninitialized: true,
        cookie: {
            path: '/',
            httpOnly: true,
            secure: false,
            maxAge: null
        },
        rolling: true,
        store: dbConnect
    }));
    app.use(flash());

    /* #Set up passport ------------------------------------------------- */
    // use passport session
    app.use(passport.initialize());
    app.use(passport.session());
};

Server.js

/* #Mongo --------------------------------------------------------------------- */
var db = require('./app/db')(app, config);

/* #Express Settings --------------------------------------------------------------------- */
require('./config/express')(app, config, passport, db);

我认为对此唯一合乎逻辑的解释是我以错误的顺序包含了文件，因此无法保存 session ？

sessionStore 需要在 db.js 中返回，而不是 module.exports = sessionStore; .
