heroku 电报机器人，BadRequest：Bad webhook：保留 IP 地址 0.0.0.0

Question

我创建了一个简单的电报机器人：

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。 之后

Stopping process with SIGKILL
Process exited with status 137

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，例如 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。

与端口类似的问题：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() 函数已经使用参数webhook_url 调用了set_webhook，这会导致您的错误。

参考：https://python-telegram-bot.readthedocs.io/en/stable/telegram.ext.updater.html

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

Answer 2

您应该将第 52 行的 updater.start_webhook 部分更改为：

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