Simple python secure websocket server/client with optional authentication built in.
This is just a simple wrapper around autobahn that removes the need to write a bunch of boiler plate code if you just want a simple and secure server client to send messages back and forth. It has optional diffie-helman-based authentication (what? dh isn't for authentication?).
You still need to create your own ssl certs and keys. You can follow this guide on how to create a locally signed cert/key combo:
https://tripzero.io/general/secure-websocket-server-using-autobahn-and-trollius-asyncio/
You can also use letsencrypt.org to create cert/keys.
basic usage:
import wss
import trollius as asyncio
loop = asyncio.get_event_loop()
server = wss.Server(port=1234, usessl=True, sslcert="path/to/cert.crt",
sslkey="path/to/server.key", auth=None)
def onTextMessage(server, msg, client):
print("got message from client:", msg)
def onBinaryMessage(server, msg, client):
print("got binary message")
server.onMessage = onTextMessage
server.onBinaryMessage = onBinaryMessage
@asyncio.coroutine
def sendData():
while True:
try:
print("trying to broadcast...")
s.broadcast("{'hello' : 'world' }")
except:
exc_type, exc_value, exc_traceback = sys.exc_info()
traceback.print_tb(exc_traceback, limit=1, file=sys.stdout)
traceback.print_exception(exc_type, exc_value, exc_traceback,
limit=2, file=sys.stdout)
yield asyncio.From(asyncio.sleep(30))
loop.create_task(sendData())
server.start()
loop.run_forever()
