会话未定义 – 使用Connect-Redis / ExpressJS / Node

今天早上，我醒来发现Nodejitsu旋转出现以下错误：

Warning: connection.session() MemoryStore is not designed for a production environment, as it will leak memory, and will not scale past a single process.

'好吧！' 我想到了自己 – 然后我去find更合适的东西。 我决定使用Redis，并立即开始在我的应用程序中实现connect-redis和node-redis 。

但是，在重复尝试修复之后，以下错误仍然存​​在。 错误如下：

 TypeError: Cannot set property 'loggedIn' of undefined at /Users/Ryan/Aggregus/server.js:300:25 at Promise.<anonymous> (/Users/Ryan/Aggregus/object_models/user.js:60:5) at Promise.<anonymous> (/Users/Ryan/Aggregus/node_modules/mongoose/node_modules/mpromise/lib/promise.js:162:8) at Promise.EventEmitter.emit (events.js:95:17) at Promise.emit (/Users/Ryan/Aggregus/node_modules/mongoose/node_modules/mpromise/lib/promise.js:79:38) at Promise.fulfill (/Users/Ryan/Aggregus/node_modules/mongoose/node_modules/mpromise/lib/promise.js:92:20) at /Users/Ryan/Aggregus/node_modules/mongoose/lib/query.js:1813:13 at model.Document.init (/Users/Ryan/Aggregus/node_modules/mongoose/lib/document.js:243:11) at completeOne (/Users/Ryan/Aggregus/node_modules/mongoose/lib/query.js:1811:10) at /Users/Ryan/Aggregus/node_modules/mongoose/lib/query.js:1779:11 

loggedIn只是指req.session.loggedIn ，一个会话variables，我用来跟踪login的用户。 以下是有问题的应用程序代码：

 var express = require('express'); var crypto = require('crypto'); var mongoose = require('mongoose'); var nodemailer = require('nodemailer'); var request = require('request'); var underscore = require('underscore'); var mandrill = require('node-mandrill')('0bFNPDenlDiZtu7aXujDQQ'); var connect = require('connect'); var engines = require('consolidate'); var fs = require('fs'); var redis = require("redis").createClient(); var RedisStore = require('connect-redis')(express); var sessionStore = new RedisStore({ client: redis }); var stripe_api_key = 'KEY'; var Stripe = require('stripe')(stripe_api_key); var app = express(); app.configure(function() { app.engine('html', engines.jade); app.set('view engine', 'html'); app.use(express.cookieParser()); app.use(express.bodyParser()); app.use(express.session({secret: "svtabyrki4q786as37c785ta8vi56aiw4i8w467acv", store: sessionStore})); app.use(express.static(__dirname + '/www')); app.use(express.compress()); app.use(app.router); }); // Mongoose Connection var db = mongoose.connection; var dbURI = 'HIDDENURL'; db.on('disconnected', function() { mongoose.connect(dbURI, {server:{auto_reconnect:true}}); }); db.on('error', function(error) { console.error('Error in MongoDb connection: ' + error); mongoose.disconnect(); }); mongoose.connect(dbURI, {server:{auto_reconnect:true}}); // Mongoose Object Models var User = require('./object_models/user')(mongoose, nodemailer, mandrill); var Notifications = require('./object_models/notification')(mongoose, nodemailer); var Experience = require('./object_models/experience')(mongoose, nodemailer); var Booking = require('./object_models/booking')(mongoose, nodemailer); var Review = require('./object_models/review')(mongoose, nodemailer); var Heart = require('./object_models/heart')(mongoose, nodemailer); var Message = require('./object_models/message')(mongoose, nodemailer); // Nodemailer Settings var smtpTransport = nodemailer.createTransport("SMTP",{ service: "Gmail", auth: { user: "[e-mail]", pass: pwd } }); // Bootstrap Call app.get('/', function(req, res) { res.render('../index.html'); console.log("WUSUP"); }); 

为了进一步澄清，这里是我尝试过，直到这一点无济于事：

1. 我已经放置了app.use(express.cookieParser()); 之前的express.session电话，这个问题的大部分文章build议。
2. 我确保了new RedisStore调用在初始化时直接引用client 。
3. 在两个express.session和“express.cookieParser”的init调用之后，我已经放置了app.use(app.router) 。
4. 通过createClient()调用，我的Redis服务器function完整。

这个类似的问题通过阻止一个相当微不足道的app.use初始化，在app.router被初始化之前调用app.router来解决。

因此，TL; DR：在使用connect-redis ，我的会话variables返回undefined 。 我已经在网上寻找答案，而我唯一的线索就是在Express自己的会话处理之前启动app.router 。 那个小小的故障发生在我身上。 堆栈溢出的神怜悯我可怜的灵魂。

编辑：认为package.json可能是方便参考。 通过NodeJitsu生成：

 { "name": "Aggregus", "subdomain": "aggregus-Aggregus", "scripts": { "start": "node server.js" }, "version": "0.0.0-14", "engines": { "node": "0.8.x" }, "dependencies": { "connect": "2.7.8", "consolidate": "0.9.1", "express": "3.2.2", "jade": "0.30.0", "mongoose": "3.6.9", "node-mandrill":"1.0.1", "nodemailer": "0.4.1", "request":"2.22.0", "stripe": "1.3.0", "underscore":"1.4.4" } }

你正在调用connect-redis错误，你不需要单独安装redis。 不过，我在package.json中看不到connect-redis，所以你应该npm install --save connect-redis 。 然后做这样的事情：

 var express = require('express'); var RedisStore = require('connect-redis')(express); var ports = require('./classes/ports.js'); var config = require('./config/config.js'); var routes = require('./routes'); var errors = require('./classes/errors.js'); var app = express(); ports(app); app .use(express.logger()) .use(express.compress()) .use(express.cookieParser()) .use(express.session({ store: new RedisStore({ port: config.redisPort, host: config.redisHost, db: config.redisDatabase, pass: config.redisPassword }), secret: 'Your secret here', proxy: true, cookie: { secure: true } })) .use(express.favicon(__dirname + '/../public/img/favicon.ico')) .use(express.bodyParser()) .use(express.methodOverride()) routes(app); errors(app);
