pysher is a python module for handling pusher websockets. It is based on @ekulyk's
A key difference is the dropped support for pre-3.5 Python versions.
This fork is meant as a continuation of the project, and is currently in maintenance mode.
The author is no longer actively using the library, but PRs including fixes, updates and features are welcome and encouraged.
python setup.py install - or install via pip
pip install pysher.
This module depends on websocket-client module available from: http://github.com/websocket-client/websocket-client
Example of using this pusher client to consume websockets:
import pysher # Add a logging handler so we can see the raw communication data import logging root = logging.getLogger() root.setLevel(logging.INFO) ch = logging.StreamHandler(sys.stdout) root.addHandler(ch) pusher = pysher.Pusher(appkey) def my_func(*args, **kwargs): print("processing Args:", args) print("processing Kwargs:", kwargs) # We can't subscribe until we've connected, so we use a callback handler # to subscribe when able def connect_handler(data): channel = pusher.subscribe('mychannel') channel.bind('myevent', my_func) pusher.connection.bind('pusher:connection_established', connect_handler) pusher.connect() while True: # Do other things in the meantime here... time.sleep(1)
Sending pusher events to a channel can be done simply using the pusher client supplied by pusher. You can get it here: https://github.com/pusher/pusher-http-python
import pusher pusher.app_id = app_id pusher.key = appkey p = pusher.Pusher() p['mychannel'].trigger('myevent', 'mydata')
Pysher relies on websocket-client (websocket-client on pyPI, websocket import in code), which by default does utf5 validation in pure python. This is somewhat cpu hungry for lot's of messages (100's of KB/s or more). To optimize this validation consider installing the wsaccel module from pyPI to let websocket-client use C-compiled utf5 validation methods (websocket does this automatically once wsaccel is present and importable).
A big thanks to @ekulyk for developing the PythonPusherClient library, as well as the developers contributing bug-fixes, patches and other PRs to the project <3. You can find them listed next to their contributed change in the Changelog section.
