Question

我正在将node.js与socket.io和redisStore用于我的快速会话。在我的套接字握手，我想读取cookie以获取会话cookie，所以我能够读取和写入会话。这是我到目前为止所得到的：

在我的app.js中：

var express = require('express');
var app = express();

var redis = require('redis');
var redisClient = redis.createClient(6379, 'localhost');

server = http.createServer(app);
server.listen(8080, function() {
  console.log('listening on *:8080');
});

var io = require('./routes/index').listen(server);
var routes = require('./routes/index').router;

app.use(session({
    secret: 'my-secret-string',
    key: 'express.sid',
    cookie: { maxAge: 2628000000 },
    store: new (require('express-sessions'))({
        storage: 'redis',
        instance: redisClient,
        host: 'localhost',
        port: 6379, 
    }),
    resave: true,
    saveUninitialized: true
}));

app.use('/', routes);

module.exports = app;

和我的index.js：

var express = require('express');
var router = express.Router();

var socketio = require('socket.io');
var io;

router.get('/', function(req, res) {
    //do stuff here...
    res.render('index', { params: params });
}

var listen = function(app) {

    io = socketio.listen(app);

    io.sockets.on('connection', function (socket) {

        console.log(socket.handshake); // there is an handshake object with cookie information
                                       // which i can parse the express.sid (=sessionID) from

        socket.on('someEvent', function(args, callback) {
            //do stuff here 
            callback(err, msg);
        });
    });
    return io;  
}

module.exports = {
    listen: listen,
    router: router
}

现在，当客户端发出＆＃34; someEvent＆＃34;时，我想从会话cookie中读取会话ID并对会话数据进行处理。

我关注了this指南和this，但它们似乎已经过时或者不适合我的设置。到目前为止没有运气。非常感谢帮助！这是我的第一个node.js项目..
