Connect to websocket.org echo service

[fajarmf]

Hi,
I want to use socket io client that can work with the echo service of http://websocket.org/echo.html (ws://echo.websocket.org). However I tried creating the following code:

<script src="/socket.io/socket.io.js"></script>
<script>
  var socket = io.connect('ws://echo.websocket.org');
  console.log('done connect');
  socket.on('connect', function (data) {
    socket.send('hi from me');
  });
  console.log('done setup');
</script>

But I cannot seems to make it works, i.e. I didn't get the echo from the server.

Thanks in advance,

Idos

Well the socket.io client is expecting to connect to a socket.io server, so this just plain won't work...
Maybe try web-socket-js if you're looking for a plain 'ol WebSocket fallback...

Does it also mean that the socket-io server will not work with other websocket client?

A regular websocket client can connect to a socket.io server, but there will be socket.io's framing and heartbeats included; that's what the socket.io client abstracts away (for the websocket transport at least).

When you say a normal websocket client can connect to socket.io server. Should the xlient point to server with ws:// or http:// adress?

I am asking this because I have the client on android device, it works with websocket.org demo server. But it couldnt connect to my socket io swrver

You need to the socket.io encoding to be able to communicate with the Socket.IO server. See github.com/learnboost/socket.io-spec for details about it.
