Question

我最近尝试运行nodejs聊天演示并测试它。它在程序运行的同一台计算机上运行，但无法从外部联系到聊天。这是服务器的代码：

    var WebSocketServer = require('ws').Server
    var wss = new WebSocketServer({host: 'put_my_ip_in_here',port: 8000});
    wss.on('connection', function(ws)
    {
        console.log('client connected...');
        ws.on('message', function(message)
        {
            console.log('received from client: ' + message);
            ws.send('received from server: ' + message);
        });
    });

我解锁了端口8000（udp和tcp，就像我的路由器和我的防火墙一样，并告诉我网络外的人打开以下页面

<!DOCTYPE html>
<html>
<head>
<script src="http://ajax.googleapis.com/ajax/libs/jquery/1.4.2/jquery.min.js"></script>
<script type="text/javascript">
$(document).ready(function()
{
    function connect()
    {
        var socket = new WebSocket("ws://put_my_ip_in_here:8000");
        socket.onopen   = function()    { message('Socket Status: '+socket.readyState+' (open)');   }
        socket.onmessage= function(msg) { message('received: '+msg.data);                           }
        function send()
        {
            var text = $('#text').val();
            socket.send(text);
            message('sent : '+text)
            $('#text').val("");
        }
        {
            $('#Log').append(msg+'</br>');
        }
        $('#text').keypress(function(event)
        {
            if (event.keyCode == '13')
            {
                send();
            }
        });
    }

    connect();

});
</script>
</head>
<body>
    <div id="container">
        <div id="Log"></div>
        Input: <input id="text" type="text" />
    </div>
</body>
</html>

但我的电脑/聊天无法访问：c 问题出在哪儿？演示似乎运行良好！

从网络外部到达服务器
