无效的 webhook url 指定 Telegram bot 中的错误

Question

我正在尝试制作一个简单的电报回声机器人并在其中使用 webhook（ngrok）。 我收到此错误，我似乎无法弄清楚我做错了什么。 我也尝试释放端口 8443，但仍然没有。

我得到的错误（URL 是正确的，我直接从运行 ngrok 终端复制它）：

(myvenv) (base) akriti@hp:~/Desktop/Get-Informed$ python bot.py
Traceback (most recent call last):
  File "bot.py", line 61, in <module>

    raise BadRequest(message)
telegram.error.BadRequest: Invalid webhook url specified

以下是我的代码：

import logging 
from flask import Flask, request
from telegram import Update, Bot
from telegram.ext import Updater, CommandHandler, MessageHandler, Filters, CallbackContext, Dispatcher


# enable logging
logging.basicConfig(format='%(asctime)s - %(name)s - %(levelname)s - %(message)s', level=logging.INFO)
logger = logging.getLogger(__name__)

TOKEN = "213181**********"

# create Flask app object
app = Flask(__name__)

@app.route('/')
def index():
    return "Hello!"

# create view to handle webhooks
@app.route(f'/{TOKEN}', methods=['GET', 'POST'])
def webhook():
    """webhook view which receives updates from telegram"""
    # create update object from json-format request data
    update = Update.de_json(request.get_json(), bot)
    # process update
    dp.process_update(update)
    return "ok"


def start(update: Update, context: CallbackContext):
    print(update)
    author = update.message.from_user.first_name
    # msg = update.message.text
    reply = "Hi! {}".format(author)
    context.bot.send_message(chat_id = update.message.chat_id, text=reply)
     

def _help(update: Update, context: CallbackContext):
    help_txt = "Hey! This is a help text."
    context.bot.send_message(chat_id = update.message.chat_id, text=help_txt)


def echo_text(update: Update, context: CallbackContext):
    reply = update.message.text
    context.bot.send_message(chat_id = update.message.chat_id, text=reply)
    

def echo_sticker(update: Update, context: CallbackContext):
    context.bot.send_sticker(chat_id = update.message.chat_id, sticker=update.message.sticker.file_id)


def error(update, context):
    logger.error("Update '%s' caused error '%s'", update, update.error)


if __name__ == "__main__":

    bot = Bot(TOKEN)
    # set webhook for telegram bot 
    bot.set_webhook("http://c026-122-161-51-216.ngrok.io" + TOKEN)

    dp = Dispatcher(bot, None)
    # add handlers
    dp.add_handler(CommandHandler("start", start))
    dp.add_handler(CommandHandler("help", _help))
    dp.add_handler(MessageHandler(Filters.text, echo_text))
    dp.add_handler(MessageHandler(Filters.sticker, echo_sticker))
    dp.add_error_handler(error)
    app.run(port=8443)

"http://c026-122-161-51-216.ngrok.io" + TOKEN将导致"http://c026-122-161-51-216.ngrok.ioTOKEN" ，这不是有效的 URL . 您可能希望使用"http://c026-122-161-51-216.ngrok.io/" + TOKEN
