我很难让多人游戏成为多台计算机，而不仅仅是多浏览器标签。我浏览了 HTML5 中的实时多人游戏教程（构建新游戏，点击这里）。它侦听端口 4004，但我无法通过访问 192.168.1.4:4004 从局域网的另一台计算机连接，即使我可以通过访问 192.168.1.4 连接到端口 80 上的 Apache Web 服务器（我已经禁用了 Apache并在我的路由器上转发端口 80，而不是转发端口 4004）。我曾经通过访问 my-domain.com（它的 DNS 由我的 ISP 托管）从外部世界连接到 Apache。现在我无法通过访问 my-domain.com 或 my-domain.com:4004 从 LAN 外部连接到我的教程。本教程使用 node.js、socket.io 和 express。你通过输入开始它node app.js在一个终端。127.0.0.1:4004您通过访问或添加新玩家192.168.1.4:4004。这是 app.js 的内容：
var
gameport = process.env.PORT || 4004,
express = require('express'),
UUID = require('node-uuid'),
verbose = false,
app = express()
, http = require('http')
, server = http.createServer(app)
, io = require('socket.io').listen(server);
/* Express server set up. */
//The express server handles passing our content to the browser,
//As well as routing users where they need to go. This example is bare bones
//and will serve any file the user requests from the root of your web server (where you launch the script from)
//so keep this in mind - this is not a production script but a development teaching tool.
//Tell the server to listen for incoming connections
server.listen( gameport );
//Log something so we know that it succeeded.
console.log('\t :: Express :: Listening on port ' + gameport );
//By default, we forward the / path to index.html automatically.
app.get( '/', function( req, res ){
res.sendfile( __dirname + '/index.html' );
});
//This handler will listen for requests on /*, any file from the root of our server.
//See expressjs documentation for more info on routing.
app.get( '/*' , function( req, res, next ) {
//This is the current file they have requested
var file = req.params[0];
//For debugging, we can track what files are requested.
if(verbose) console.log('\t :: Express :: file requested : ' + file);
//Send the requesting client the file.
res.sendfile( __dirname + '/' + file );
});
/* Socket.IO server set up. */
//Express and socket.io can work together to serve the socket.io client files for you.
//This way, when the client requests '/socket.io/' files, socket.io determines what the client needs.
//Create a socket.io instance using our express server
var sio = io;
//Configure the socket.io connection settings.
//See http://socket.io/
sio.configure(function (){
sio.set('log level', 0);
sio.set('authorization', function (handshakeData, callback) {
callback(null, true); // error first callback style
});
});
//Enter the game server code. The game server handles
//client connections looking for a game, creating games,
//leaving games, joining games and ending games when they leave.
game_server = require('./game.server.js');
//Socket.io will call this function when a client connects,
//So we can send that client looking for a game to play,
//as well as give that client a unique ID to use so we can
//maintain the list if players.
sio.sockets.on('connection', function (client) {
//Generate a new UUID, looks something like
//5b2ca132-64bd-4513-99da-90e838ca47d1
//and store this on their socket/connection
client.userid = UUID();
//tell the player they connected, giving them their id
client.emit('onconnected', { id: client.userid } );
//now we can find them a game to play with someone.
//if no game exists with someone waiting, they create one and wait.
game_server.findGame(client);
//Useful to know when someone connects
console.log('\t socket.io:: player ' + client.userid + ' connected');
//Now we want to handle some of the messages that clients will send.
//They send messages here, and we send them to the game_server to handle.
client.on('message', function(m) {
game_server.onMessage(client, m);
}); //client.on message
//When this client disconnects, we want to tell the game server
//about that as well, so it can remove them from the game they are
//in, and make sure the other player knows that they left and so on.
client.on('disconnect', function () {
//Useful to know when soomeone disconnects
console.log('\t socket.io:: client disconnected ' + client.userid + ' ' + client.game_id);
//If the client was in a game, set by game_server.findGame,
//we can tell the game server to update that game state.
if(client.game && client.game.id) {
//player leaving a game should destroy that game
game_server.endGame(client.game.id, client.userid);
} //client.game_id
}); //client.on disconnect
}); //sio.sockets.on connection
我意识到端口转发和路由器问题可能超出了大多数多人游戏教程的范围。不过，我希望有人可以在这里帮助我。谢谢。
