I got it to work in Google Chrome. I had no issues, there must be something you did wrong.

This should work with the latest version of Google chrome.

If not try the updated Firefox. That will work for sure.

“It will also work if you open the page in multiple browser windows or even if you open the page in different computers.”

I am having difficulty getting this to work with Google Chrome – any suggestions guys?

The WebSocket protocol changed, to include a quite weird handshake. I’ve modified your example to work with the new protocol, posted on StackOverflow:

circuits.web (1) as of revision fe3965b21fe2 now implements a working WebSockets Server:

https://bitbucket.org/prologic...

This allows you to have a WebSockets server that sits alongside your application server (no need for a separate server, etc). This will be integrated into the circuits.web namespace before the next release.

Thanks for your blog ! I have not used any thread and this is what I get :

while 1:
ssock, saddr = s.accept()
print(‘Connected by’, saddr)
data = ssock.recv(4096)
while 1 :
data = s.recv(1024)
print(‘Data from’, saddr, ‘:’, data)
ssock.sendall(data)

Unfortunately, this does not work ! Why ?

It is the same if I add the handshake :

while 1:
ssock, saddr = s.accept()
print(‘Connected by’, saddr)
handsake = “HTTP/1.1 101 Web Socket Protocol Handshake\r\nUpgrade: WebSocket\r\nConnection: Upgrade\r\nWebSocket-Origin: http://%s\r\nWebSocket-Location: ws://%s/\r\nWebSocket-Protocol: sample\r\n\r\n” % (httphost, sockethost)
s.send(handsake)
data = ssock.recv(4096)
while 1 :
data = s.recv(1024)
print(‘Data from’, saddr, ‘:’, data)
ssock.sendall(data)

Do you know why ? In both cases, I get the same following error : [Errno 10057] socket is not connected, no address.
Is it because I use no thread ?

Thanks for your help !
