node.js - 如何在 WebSocket 上生成 "room"

Question

我正在使用WebRTC“库”，它允许用户通过点对点连接传输音频、视频等。为此，我需要在 Internet Explorer 中通过 WebSocket 启动连接。

我选择了 heroku.com 作为我的 Node.js 托管。

这是我的服务器文件，我需要将用户添加到“房间”，但它崩溃了，如下所示:

var WebSocketServer = require("ws").Server;
var http = require("http");
var cool = require('cool-ascii-faces');
var express = require('express');
var app = express();
var port = process.env.PORT || 5000;
app.set('port', (process.env.PORT || 5000));

app.use(express.static(__dirname + '/public'));

// views is directory for all template files
app.set('views', __dirname + '/views');
app.set('view engine', 'ejs');

app.get('/', function(request, response) {
  response.render('pages/index')
});

app.get('/cool', function(request, response) {
  response.send(cool());
});

app.use(express.static(__dirname + "/"))

var server = http.createServer(app)
server.listen(port)

console.log("http server listening on %d", port)

var wss = new WebSocketServer({server: server})
console.log("websocket server created")

wss.on("connection", function(ws) {
  console.log("websocket connection open")

  ///////////////
  // I NEED HELP HERE
  ws.on('message', function(room) {
        console.log("I am trying to create room: " + room);

        ws.join(room); // this line is crashing
                        // with error "There is NO function join"


    });

  ws.on("close", function() {
    console.log("websocket connection close")
  })
})

这是我的客户端，我在其中发送了我想要创建的房间的名称:

var host = location.origin.replace(/^http/, 'ws')
var ws = new WebSocket(host);
waitForSocketConnection(ws);
ws.onmessage = function (event) {
    console.log('got ' + event);
    console.log('got2 ' + event.data);
};

function waitForSocketConnection(socket){
        setTimeout(
            function(){
                if (socket.readyState === 1) {
                    socket.send("Lukasz30M");
                    return;
                } else {
                    waitForSocketConnection(socket);
                }
            }, 5);
    };

这是 WebRTC 提供的示例，我正在尝试遵循:

var static = require('node-static');
var http = require('http');
var file = new(static.Server)();
var app = http.createServer(function (req, res) {
  file.serve(req, res);
}).listen(2013);

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

io.sockets.on('connection', function (socket){

  // convenience function to log server messages on the client
    function log(){
        var array = [">>> Message from server: "];
      for (var i = 0; i < arguments.length; i++) {
        array.push(arguments[i]);
      }
        socket.emit('log', array);
    }

    socket.on('message', function (message) {
        log('Got message:', message);
    // for a real app, would be room only (not broadcast)
        socket.broadcast.emit('message', message);
    });

    socket.on('create or join', function (room) {
        var numClients = io.sockets.clients(room).length;

        log('Room ' + room + ' has ' + numClients + ' client(s)');
        log('Request to create or join room ' + room);

        if (numClients === 0){
            socket.join(room);
            socket.emit('created', room);
        } else if (numClients === 1) {
            io.sockets.in(room).emit('join', room);
            socket.join(room);
            socket.emit('joined', room);
        } else { // max two clients
            socket.emit('full', room);
        }
        socket.emit('emit(): client ' + socket.id + ' joined room ' + room);
        socket.broadcast.emit('broadcast(): client ' + socket.id + ' joined room ' + room);

    });

});

谢谢你的指点。我完全停止了;)
