Using a websocket client as a class in python

Question

I\'m trying access some data using websockets, but I cannot really get around the examples given in the websockets documentation.

I have this code (https://pypi.org/proj

Answer 1

Package the call inside an anonymous lambda function to achieve a proper call with the correct self:

class Client:
    def __init__(self, db, symbols):
        self.ws = websocket.WebSocketApp("wss://the.server.com/api",
                    on_message = lambda ws,msg: self.on_message(ws, msg),
                    on_error   = lambda ws,msg: self.on_error(ws, msg),
                    on_close   = lambda ws:     self.on_close(ws),
                    on_open    = lambda ws:     self.on_open(ws))

    def on_message(self, ws, message):
            msg = json.loads(message)
            print(msg)
    ...
