python - heroku Telegram Bot ，BadRequest : Bad webhook: ip address 0. 0.0.0 被保留

Question

我创建了一个简单的 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()

当我在本地机器上运行它时，它工作正常。当我根据 this link 编辑它以应用于 heroku Web 服务器时.然后它给了我这样的错误:telegram.error.BadRequest: Bad webhook: ip address 0.0.0.0 is reserved或者，如果我更改了端口，那么它会说，我只能使用 443/8443/80 端口。
在那之后

Stopping process with SIGKILL
Process exited with status 137

和机器人不工作。我已经设置了 Procfile，requirements.txt。我已阅读有关此错误的信息，但一无所获。
当然，我设置了我的 TOKEN 和我的应用程序名称。
有时，如果我修改我的端口，如 PORT = 443 它写道:

telegram.error.BadRequest: Bad webhook: webhook can be set up only on ports 80, 88, 443 or 8443

并退出137错误状态。
端口的类似问题:without answer

Answer 1

尝试改变

updater.start_webhook(listen="0.0.0.0",
                      port=int(PORT),
                      url_path=TOKEN)
updater.bot.setWebhook('https://yourherokuappname.herokuapp.com/' + TOKEN)

到

updater.start_webhook(listen="0.0.0.0",
                      port=int(PORT),
                      url_path=TOKEN,
                      webhook_url = 'https://yourherokuappname.herokuapp.com/' + TOKEN)

start_webhook()函数已经调用 set_webhook与参数 webhook_url这会导致您的错误。

根据您的 Python 版本，您还需要添加:force_event_loop=True
