如何重新连接 websocket 连接 websocket-client

Question

I've been trying to write code that collects crypto data from Binance. Binance auto disconnects after 24 hours. Is there any way for me to reconnect after disconnection? I believe running forever should take care of that for me, but it dies when an error is thrown. I will be running this program on a server 24/7. I will also need a way to be notified maybe telegram/discord bot that I can build where do I type the code to send when it is disconnected

This is the error I get.

My code:

import websocket

uri = "wss://stream.binance.com:9443/ws/!ticker@arr"


def on_message(ws, message):
print(message)


def on_error(ws, error):
print(error)
write_logs(error)


def on_close(ws, close_status_code, close_msg):
print("### closed ###")
write_logs(str(close_status_code) + str(close_msg))
start(


def on_open(ws):
print("Opened connection")


start()
websocket.enableTrace(True)
ws = websocket.WebSocketApp(uri,
on_open = on_open,
on_message=on_message,
on_error = on_error,
on_close (on_close)
ws.run_forever(dispatcher=rel) #Set the dispatcher to automatic reconnection.
rel.signal(2, rel.abort) # Keyboard Interrupt
rel.dispatch()


    
start()

Answer 1

The comment in this line of code ws.run_forever(dispatcher=rel) #Set the dispatcher to automatic reconnection. could auto reconnection depending on rel module? And how the module rel and func dispatcher work together?
