标签: javascript html node.js socket.io

我刚开始使用node.js,我在我的主机上安装节点,添加一些插件,我从

下载socket.io示例聊天
  

https://github.com/socketio/chat-example.git

当我运行它(node index.js)时,我在控制台上得到警报"收听*:3000"并且看起来一切都会正常工作,但是当我在3000端口(coracko.com:3000)上访问我的网站时,聊天是可见的,但是消息没有发送,也没有任何反应。



var app = require('express')();
var http = require('http').Server(app);
var io = require('socket.io')(http);
var port = process.env.PORT || 3000;

app.get('/', function(req, res){
  res.sendFile(__dirname + '/index.html');
});

io.on('connection', function(socket){
  socket.on('chat message', function(msg){
    io.emit('chat message', msg);
  });
});

http.listen(port, function(){
  console.log('listening on *:' + port);
});

如果重要,脚本现在在coracko.com:3000上运行
