node.js - Req.session undefined with express 4 and Redis store, express-session

Question

似乎无法弄清楚如何将 redis 存储用于 Express 4 的 session ，一些示例代码如下所示:

var express       = require('express');
var app           = express();
var cookieParser  = require('cookie-parser');
var bodyParser    = require('body-parser');
var session       = require('express-session');
var RedisStore    = require('connect-redis')(session);

app.use(cookieParser());
app.use(session({
    store: new RedisStore({
        host: 'localhost',
        port: 6379,
    }),
    secret: 'secret',
    resave: false,
    saveUninitialized: true
}));
app.get('/', function (req, res) {
    console.log(req.session); // undefined! :(
});
app.listen(3000);

如你所见，上面的 req.session 似乎总是未定义的，显然无法在其中存储任何变量......

当然，最令人沮丧的问题有最简单的答案……从未安装过 Redis 客户端。将来任何人的链接 - http://redis.io/topics/quickstart :脸掌:
