How to make webhook in telegram bot and put it on hosting?

Question

Python

I am using Telebot library. It's time to put the bot on the host (I want to use Pythonanywhere). Now the bot works on bot.polling(), I want to transfer it to Webhook, but after looking at the documentation I didn’t understand anything exactly how to do it.
Tell me how to make a webhook and how to upload it to the hosting?

Answer 1

In the secret of some kind of line, so that no one needs to poke once again.
First you need to remove the hook, suddenly it already exists, then re-attach. username - name on pythonanywhere
Then we hang the hook.

secret = '43d2yIyIVM'
username = 'user'

bot.remove_webhook()
time.sleep(1)
bot.set_webhook(url='https://{}.pythonanywhere.com/{}'.format(username, secret))

app = Flask(__name__)

Then the flask handler is hung up, updates come to it and are transferred to telebot

@app.route('/{}'.format(secret), methods=["POST"])
def webhook():
    bot.process_new_updates([telebot.types.Update.de_json(request.stream.read().decode("utf-8"))])
    return 'ok', 200

The rest is the same, except that bot.pollin() is naturally not
