I create a simple telegram bot:
import logging
from telegram.ext import Updater, CommandHandler, MessageHandler, Filters
import os
PORT = int(os.environ.get('PORT', 8443))
# Enable logging
logging.basicConfig(format='%(asctime)s - %(name)s - %(levelname)s - %(message)s',
level=logging.INFO)
logger = logging.getLogger(__name__)
TOKEN = 'YOURTELEGRAMBOTTOKEN'
# Define a few command handlers. These usually take the two arguments update and
# context. Error handlers also receive the raised TelegramError object in error.
def start(update, context):
"""Send a message when the command /start is issued."""
update.message.reply_text('Hi!')
def help(update, context):
"""Send a message when the command /help is issued."""
update.message.reply_text('Help!')
def echo(update, context):
"""Echo the user message."""
update.message.reply_text(update.message.text)
def error(update, context):
"""Log Errors caused by Updates."""
logger.warning('Update "%s" caused error "%s"', update, context.error)
def main():
"""Start the bot."""
# Create the Updater and pass it your bot's token.
# Make sure to set use_context=True to use the new context based callbacks
# Post version 12 this will no longer be necessary
updater = Updater(TOKEN, use_context=True)
# Get the dispatcher to register handlers
dp = updater.dispatcher
# on different commands - answer in Telegram
dp.add_handler(CommandHandler("start", start))
dp.add_handler(CommandHandler("help", help))
# on noncommand i.e message - echo the message on Telegram
dp.add_handler(MessageHandler(Filters.text, echo))
# log all errors
dp.add_error_handler(error)
# Start the Bot
updater.start_webhook(listen="0.0.0.0",
port=int(PORT),
url_path=TOKEN)
updater.bot.setWebhook('https://yourherokuappname.herokuapp.com/' + TOKEN)
# Run the bot until you press Ctrl-C or the process receives SIGINT,
# SIGTERM or SIGABRT. This should be used most of the time, since
# start_polling() is non-blocking and will stop the bot gracefully.
updater.idle()
if __name__ == '__main__':
main()
When I run it in local machine it works fine. When I edit it to apply on heroku web server according this link. Then it's give me error like:
telegram.error.BadRequest: Bad webhook: ip address 0.0.0.0 is reserved
Or, if I changed port then it says, I can use only 443 / 8443 / 80 port.
After that
Stopping process with SIGKILL
Process exited with status 137
And bot not working. I have already setup Procfile, requirements.txt. I have read about this error and find nothing. Of course, I set up my TOKEN, and my app name. Sometimes, if I modify my port like PORT = 443 It writes:
telegram.error.BadRequest: Bad webhook: webhook can be set up only on ports 80, 88, 443 or 8443
And exit 137 error status.
Similar problem with port: without answer
