Can I use function send_message without object of RocketChat?

[HuXinjing]

I found send_message demend a RocketChat object as an input parameter, however, I couldn't get a 'self' from subscribe_to_channel_messages. So could I call send_message in callback of subscribe_to_channel_messages without 'self'?

Hi @HuXinjing ,

sorry it took me so long to respond to you. I suppose this is no longer relevant, but for the record: you need the instance and there are various ways how to make it available from within the callback. This is a hopefully straightforward (even if not ideal) example:

import asyncio
import random
from rocketchat_async import RocketChat

class Bot:
    def __init__(self, rc: RocketChat):
        self.rc = rc

    def handle_message(self, channel_id, sender_id, msg_id, thread_id,
                       msg, qualifier):
        if sender_id != self.rc.user_id:
            asyncio.create_task(self.rc.send_message("Accepted.", channel_id))

    async def run(self):
        for channel_id, channel_type in await self.rc.get_channels():
            await self.rc.subscribe_to_channel_messages(channel_id,
                                                        self.handle_message)
        await self.rc.run_forever()

async def main(address, username, password):
    while True:
        try:
            rc = RocketChat()
            await rc.start(address, username, password)
            bot = Bot(rc)
            await bot.run()
        except (RocketChat.ConnectionClosed,
                RocketChat.ConnectCallFailed) as e:
            print(f'Connection failed: {e}. Waiting a few seconds...')
            await asyncio.sleep(random.uniform(4, 8))
            print('Reconnecting...')

asyncio.run(main('ws://localhost:3000/websocket', 'varel.bot', 'jahoda'))
