我正在尝试获取当前连接的所有套接字/客户端的列表.

io.sockets 遗憾的是,它没有返回数组.

我知道我可以使用数组保留自己的列表,但不要认为这是一个最佳解决方案有两个原因:

1. 冗余.Socket.IO已经保留了此列表的副本.

2. Socket.IO提供了为客户端设置任意字段值的方法(即:),socket.set('nickname', 'superman')所以如果我要维护自己的列表,我需要跟上这些变化.

救命？

我现在有这个代码设置缺口和房间:

io.sockets.on('connection', function(client){
    var Room = "";
    client.on("setNickAndRoom", function(nick, fn){
        client.join(nick.room);
        Room = nick.room;
        client.broadcast.to(Room).emit('count', "Connected:" + " " + count);
        fn({msg :"Connected:" + " " + count});
    });

我想知道我怎么能得到有多少人连接到一个特定的聊天室......比如Room.length

客户端 :

function Chat(){
    this.socket = null;
    this.Nickname = "";
    this.Room = "";
    var synched = $('#syncUp');
    this.Connect = function(nick, room){ 
        socket =  io.connect('http://vybeing.com:8080');    
        Nickname = nick;
        Room = room;
        //conectarse
        socket.on('connect',function (data) {
            socket.emit('setNickAndRoom', {nick: nick, room: room}, function(response){
                $("#connection").html("<p>" + response.msg + "</p>");
            });
        });
}

我找到了这个,但它给出了undefined:

count …

我正在按照此链接中的教程进行操作（第 7 步）。我成功安装了 node.js 或 socket.js ，但是当我转到该页面并尝试发送图像时，我在服务器上收到此错误

我的 server.js 文件是

var os = require('os');
var static = require('node-static');
var http = require('http');
var socketIO = require('socket.io');

var fileServer = new(static.Server)();
var app = http.createServer(function (req, res) {
fileServer.serve(req, …
