node.js – 如何获取(Express的)sessionID的websocket连接

我正在Express Express运行的同一端口上使用WebSockets npm install ws.

我想从刚刚制作并升级到WebSocket的HTTP连接中提取相关联的“sessionID”.

// start express listening
server.listen(conf.server.port, conf.server.host);

var WebSocketServer = require('ws').Server
  , wss = new WebSocketServer({server: server});

wss.on('connection', function(ws) {
    var sessionID = // how do I get this?
    ws.on('message', function(message) {
        console.log('received: %s', message);
    });
    ws.send('something');
});

如何才能做到这一点？

(我目前通过在页面中发送sessionID来解决问题,但这是丑陋的.)

>解析cookie

>获取会话ID

>获取会话数据

var express = require('express');
var parseCookie = express.cookieParser();
var MemoryStore = express.session.MemoryStore;

var store = new MemoryStore();

app.configure(function() {
    app.use(express.session({ store: store, secret: '123456', key: 'sid' }));
});

wss.on('connection', function(ws) {
    parseCookie(ws.upgradeReq, null, function(err) {
        var sessionID = ws.upgradeReq.cookies['sid'];
        store.get(sessionID, function(err, session) {
            // session
        });
    }); 

    ws.on('message', function(message) {
        console.log('received: %s', message);
    });
    ws.send('something');
});
