问如何使用socket.io将tcp报文发送到远程服务器

EN

var app = require('http').createServer(handler)
var io = require('socket.io')(app);
var fs = require('fs');

app.listen(8000);

function handler (req, res) {
  fs.readFile(__dirname + '/index.html',
  function (err, data) {
    if (err) {
      res.writeHead(500);
      return res.end('Error loading index.html');
    }

    res.writeHead(200);
    res.end(data);
  });
}

io.on('connection', function (socket) {
  console.log("user connected!")
  socket.on('message', function (message) {
    //Sends message to all connected sockets
    socket.broadcast.emit("message")
  });
});

<script src="/socket.io/socket.io.js"></script>
<script>
  var socket = io('http://server-ip-or-domain-name:port');
  socket.on('message', function (message) {
    //processing incoming message here
    console.log(message);
  });

  function sendMessage(msg){
      //sends message to server
      socket.emit("message", msg);
  }
</script>
