Can aiogram and flask be friends?

Bots

Can aiogram and flask be friends?
How to make "flask" and "aiogram" friends, the web interface will be written in "flask" and the bot in "aiogram" to launch the bot with a single button click in the web interface. Is it possible to run polling in a separate thread and how to do it?
webhook not considered

Answer 1

You can run in a separate process, so that later, if necessary, you can stop this process:

from multiprocessing import Process

from flask import Flask
from aiogram import Bot, Dispatcher, executor, types

import config

app = Flask(import_name=__name__)

bot = Bot(token=config.BOT_TOKEN)
dispatcher = Dispatcher(bot=bot)


def bot_start_polling():
    executor.start_polling(dispatcher=dispatcher, skip_updates=True)


@dispatcher.message_handler(commands=['start'])
async def bot_handler_start(message: types.Message):
    await message.reply('Foo')


@app.get(rule='/start_bot')
def start_bot():
    bot_process = Process(target=bot_start_polling)
    bot_process.start()

    return str(bot_process.pid)


if __name__ == '__main__':
    app.run()

But it's very stupid to do this, since you are using flask, hang up a webhook and do it normally. Any solution other than that would be a very strange crutch.
