telegram webhook with heroku

Question

I am trying to make a telegram echobot with python. I am hosting my python on heroku.

At first I just used telegrams native API methods with python requests, then I used a library python-telegram-bot.

I was able to get the regular getUpdate methods (which use long polling - that is heroku periodically makes a request to your telegram bot to get updates) working, but the webhook is not.

I think the problem is that heroku will not give access to ports <1024 and telegram webhook only pushes notifs to ports 80,88,443 and 8443.

Does anyone know how I could make this work

here is my code:

import os

import logging
import sys
logging.basicConfig(stream=sys.stdout,level=logging.DEBUG)
log = logging.getLogger('my_application')


from proj.heroku_env_vars import teleg_token,secret_key



import telegram
from flask import Flask, request

app = Flask(__name__)
app.debug = True

global bot
bot = telegram.Bot(token=TOKEN)


@app.route('/%s'%HOOK, methods=['POST'])
def webhook_handler():
    if request.method == "POST":
        log.info('post from teleg')
        # retrieve the message in JSON and then transform it to Telegram object
        update = telegram.Update.de_json(request.get_json(force=True))

        chat_id = update.message.chat.id

        # Telegram understands UTF-8, so encode text for unicode compatibility
        text = update.message.text.encode('utf-8')

        # repeat the same message back (echo)
        bot.sendMessage(chat_id=chat_id, text=text)
    else:
        log.info('notpost from teleg')

    return 'ok'


@app.route('/swh', methods=['GET', 'POST'])
def set_webhook():
    s = bot.setWebhook('%s/%s'%(URL, HOOK), PORT=8443)
    if s:
        return "webhook setup ok"
    else:
        return "webhook setup failed"


@app.route('/dwh', methods=['GET', 'POST'])
def delete_webhook():
    s = bot.deleteWebhook()
    if s:
        return "webhook deleted ok"
    else:
        return "webhook delete failed"


@app.route('/')
def index():
    log.info('i made this request')
    return 'home page.'

5. AND IF I POST A MESSAGE TO MY TELEGRAM BOT, NOTHING SHOWS UP ON MY HEROKU LOGS

Answer 1

You have to use aidentmchugh.pythonanywhere.com as URL, not include www.

Your HTTPS cert didn't signed for www domain.
