解决方案非常简单。它只是没有很好的记录。也可以通过如下所示的小型适配器将快速会话中间件用作Socket.IO中间件：
sio.use(function(socket, next) { sessionMiddleware(socket.request, socket.request.res, next);});这是Express 4.x，Socket.IO 1.x和Redis的完整示例：
var express = require("express");var Server = require("http").Server;var session = require("express-session");var RedisStore = require("connect-redis")(session);var app = express();var server = Server(app);var sio = require("socket.io")(server);var sessionMiddleware = session({ store: new RedisStore({}), // XXX redis server config secret: "keyboard cat",});sio.use(function(socket, next) { sessionMiddleware(socket.request, socket.request.res || {}, next);});app.use(sessionMiddleware);app.get("/", function(req, res){ req.session // Session object in a normal request});sio.sockets.on("connection", function(socket) { socket.request.session // Now it's available from Socket.IO sockets too! Win!});server.listen(8080);
