今天早上,我醒來時,發現Nodejitsu紡出以下錯誤會議未定義使用連接-的Redis/ExpressJS /節點
Warning: connection.session() MemoryStore is not designed for a production environment, as it will leak memory, and will not scale past a single process.
我想到了自己 - 然後我去找了更適合的東西。我決定使用Redis,並立即開始在我的應用程序中實施connect-redis
和node-redis
。
但是,在重複嘗試修復之後,下列錯誤仍然存在。錯誤如下:
TypeError: Cannot set property 'loggedIn' of undefined

loggedIn
僅僅是指req.session.loggedIn
,我用它來跟蹤登錄用戶的會話變量。以下是有問題的應用程序代碼:
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: "[email protected]",
pass: pwd
}
});
// Bootstrap Call
app.get('/', function(req, res) {
res.render('../index.html');
console.log("WUSUP");
});
爲了提供進一步明晰,這裏是我已經試過了,直到這點無濟於事:
- 我已經把之前
app.use(express.cookieParser());
到express.session
通話正如本主題的大部分文章所建議的那樣。 - 我確保我的
new RedisStore
調用在初始化時直接引用client
。 - 在兩個
express.session
和'express.cookieParser'的初始調用之後,我已經放置了app.use(app.router)
。 - 通過調用
createClient()
,我的Redis服務器功能完整。
這similar question被防止微乎其微app.use
初始化解決調用app.router
之前快速sessionStore被初始化。
因此,TL; DR:在使用connect-redis
時,我的會話變量返回undefined
。我搜索了網上的答案,我唯一的線索是app.router
在Express自己的會話處理之前正在啓動。那個小毛病發生在我身上。堆棧溢出的神憐憫我可憐的靈魂。
編輯:認爲package.json可能很方便參考。通過NodeJitsu生成:

嘿@dankohn我怎麼設置一個函數來傳遞任何請求緊接在之前設置req.user從cookie? – morgs32
你幾乎肯定想要使用護照或everyauth。以下是設置Cookie的示例,您可以在頂端附近執行此操作:http://stackoverflow.com/questions/20484649/csrf-token-not-working-when-submitting-form-in-express/20485620#20485620 – dankohn
