Incorporating Bot into Flask App

[shapiroj18]

I'm hoping to build out a bot within a flask application. Per the suggestion of @Bibo-Joshi, I followed the Custom Solution skeleton , but am falling a bit short.

My code can be seen here in pastebin. Using v13.1.

Hi. As discussed in the user group update = Update.de_json(request.get_json(force=True), bot) should lead to update.effective_message.bot being the same object as the bot passed to de_json. Could you verify that manually after forming the update, i.e. check if the update has an effective_message and if yeas, print out update.effective_message.bot is bot? if that is True, please print double check, what bot is. If it's not True, please try check, what update.effective_message.bot is. The function probably has a name, maybe that helps …

Thanks for the suggestion @Bibo-Joshi . I updated the flask route to include the following for debugging purposes:

@app.route(f"/{auth_key}", methods=["POST"])
def webhook_telegram():
    update = Update.de_json(request.get_json(force=True), bot)
    update_queue.put(update)
    print(f"update:\n{update}")
    print(f"update.effective_message:\n{update.effective_message}")
    print(f"update.effective_message.bot:\n{update.effective_message.bot}")
    print(f"bot:\n{bot}")

When I hit the webhook, I get the following:

Allright, the last two prints tell me that bot is not what you think it is. please try:

1. printing bot directly after line 9 to make sure that it's actually a Bot instance there
2. printing bot.__name__ in line 28. That should give the name of that function. maybe that tells you, what it is

I don't know much about flask, though, so I can't tell, if you e.g. need to pass bot to the webhook_telegram callback in a different way …

For sure -

For 1:

bot = Bot(auth_key)
print(f"bot:\n{bot}")

Response:

bot:
{'id': 1561152901, 'username': 'devlocal_gone_phishing_bot', 'first_name': 'Dev Local Phish Bot'}

For 2:

@app.route(f"/{auth_key}", methods=["POST"])
def webhook_telegram():
    update = Update.de_json(request.get_json(force=True), bot)
    print(f"bot.__name__:\n{bot.__name__}")
    update_queue.put(update)    

Response:

bot.__name__:
bot

[Bibo-Joshi]

Mh, first printout looks good, the second is not too helpful … maybe you need to call de_json(…, bot())? Anyway, at this point I'm inclined to say that it's a flask problem, as the issue is to properly access bot in webhook_telegram.

@Bibo-Joshi thanks for all of your help on this - unfortunately there wasn't a good solution here, but from a design perspective I realized it made sense to make the bot application separate from the flask app itself. Now I have it just work with the API I built in Flask.

Appreciate all of this once again!

[Bibo-Joshi]

Hey, no. Also sorry, for not replying, must have missed the notification. Regardles of how you proceed:

For 2:

@app.route(f"/{auth_key}", methods=["POST"])
def webhook_telegram():
   update = Update.de_json(request.get_json(force=True), bot)
   print(f"bot.__name__:\n{bot.__name__}")
   update_queue.put(update)    

Response:

bot.__name__:
bot

This tells me, that in webhook_telegram() the variable bot for some reason is a function named bot. Don't know what flask does here …
