ws4py provides high-level, yet simple, interface to provide your application with WebSocket support.
from ws4py.websocket import WebSocket
The WebSocket class should be sub-classed by your application to make something sensible with it. To the very least we suggest you override the received_message(message) method.
For instance a straightforward echo application would look like this:
class EchoWebSocket(WebSocket):
def received_message(self, message):
self.send(message.data, message.is_binary)
Other useful methods to implement are:
- opened() which is called whenever the WebSocket handshake is done.
- closed(code, reason=None) which is called whenever the WebSocket connection is terminated.
You may want to know if the connection is currently usable or terminated.
