我正在使用快递框架.我想从socket.io访问会话数据.我尝试使用client.listener.server.dynamicViewHelpers数据表达dynamicHelpers,但我无法获取会话数据.有一个简单的方法吗？请参阅代码

app.listen(3000);

var io = require('socket.io');
var io = io.listen(app);

io.on('connection', function(client){
    // I want to use session data here
    client.on('message', function(message){
        // or here
    });
    client.on('disconnect', function(){
        // or here
    }); 
});

如何与Socket.io 1.0和Express 4.x共享会话？我使用Redis商店,但我认为这无关紧要.我知道我必须使用中间件来查看cookie和获取会话,但不知道如何.我搜索但找不到任何工作

    var RedisStore = connectRedis(expressSession);
    var session = expressSession({
        store: new RedisStore({
            client: redisClient
        }),
        secret: mysecret,
        saveUninitialized: true,
        resave: true
    });
    app.use(session);

    io.use(function(socket, next) {
        var handshake = socket.handshake;
        if (handshake.headers.cookie) {
            var str = handshake.headers.cookie;
            next();
        } else {
            next(new Error('Missing Cookies'));
        }
    });

使用最新版本的connect(截至2012-07-26),我发现以下方法可以从socket.io获取可与connect-redis存储一起使用的会话ID.

var express = require('express')
, routes = require('./routes')
, fs = require('fs')
, http = require('http')
, io = require('socket.io')
, redis = require('connect-redis')
, connect = require('express/node_modules/connect')
, parseSignedCookie = connect.utils.parseSignedCookie
, cookie = require('express/node_modules/cookie');

var secret = '...';
var rStore = new(require('connect-redis')(express));

//...

var server = http.createServer(app);
var sio = io.listen(server);

sio.set('authorization', function(data, accept) {
    if(data.headers.cookie) {
        data.cookie = cookie.parse(data.headers.cookie);
        data.sessionID = parseSignedCookie(data.cookie['connect.sid'], secret);
    } else {
        return accept('No cookie transmitted', false);
    }
    accept(null, true);
});

data.sessionID …
