Question

var httpsport = 8080,               // used for httpsapp
    httpport = 8000,                // used for httpapp
    numCPUs = require('os').cpus().length;

var credentials = {
    key: fs.readFileSync('./cert/client.key'),
    cert: fs.readFileSync('./cert/client.crt'),
    requestCert: true
};

var cluster = require('cluster'),
    socketStore = require('socket.io-clusterhub');

var redis = require('redis'); 
var redisClient = redis.createClient();

if(cluster.isMaster) {
    for(var i=0; i<numCPUs; i++) {
        cluster.fork();
    }
} else {
    var io = require('socket.io'),
        express = require('express'),
    httpsapp = express(),           // for https services
    httpapp = express(),            // for http services
    http = require('http'),
    https = require('https');

httpapp.configure( function () {
    httpapp.use(express.bodyParser());
    httpapp.use(express.methodOverride);
        httpapp.use(httpapp.router);
        httpapp.set('port', httpport);
    httpapp.use(express.static(__dirname+'/public', {maxAge:oneDay}));
});

httpsapp.configure( function() {
    // allow CORS
    httpsapp.all('*', function(req, res, next){
        if(!req.get('Origin')) {
            return next();
        }
        // use "*" here to accept any origin
        res.set('Access-Control-Allow-Origin', '*');
        res.set('Access-Control-Allow-Methods', 'GET');
        res.set('Access-Control-Allow-Headers', 'X-Requested-With, Content-Type');
        // res.set('Access-Control-Allow-Max-Age', 3600);
        if ('OPTIONS' === req.method) {
            return res.send(200);
        }
        next();
    });
    httpsapp.use(express.bodyParser());
    httpsapp.use(express.static(__dirname + '/public'));
    httpsapp.set('port', httpsport);    
});

var httpServer = http.createServer(httpapp),
    httpsServer = https.createServer(credentials, httpsapp),
    sio = io.listen(httpServer);

    // set the configuration for production.
sio.configure('production', function(){
    sio.enable('browser client etag');
    sio.set('log level', 1);
    sio.set('store',socketStore);
    sio.set('transports', [
        'websocket',
        'flashsocket',
        'htmlfile',
        'xhr-polling',
        'jsonp-polling'
    ]);
});

    sio.of('/namespace1').on('connection', function(socket) {

            socket.on('doSomething', function() { 
                socket.emit('reply',{hello:world}) });



    httpsapp.get("/user", function(req, res) {
                 // ...
            });
    }
}

如果使用节点集群，我收到响应：无法获取/用户。但是没有集群，它就可以为https.get（“/ user”）提供服务。

另外，使用集群，我想检查redis，http（s），socket.io和express模块是应该在workers部分声明还是全局声明？

httpsapp.get（）嵌套在套接字空间中，因为它想要回复特定的套接字。有没有办法绕过这个结构？

任何人都可以知道为什么httpsapp.get（）不服务请求？那些宣言在哪里适当？谢谢！
