如何修复“TypeError: MessageFilter.check_update() missing 1 required positional argument: 'update'”

Question

我正在使用 python-telegram-bot V20.2 创建这样的东西：聊天和用户选择

当用户共享群组/频道聊天时，我在处理事件时遇到问题。

这是我的代码：

from telegram import Update, KeyboardButton, KeyboardButtonRequestChat, ReplyKeyboardMarkup
from telegram.ext import ApplicationBuilder, CommandHandler, CallbackContext, MessageHandler, filters


bot_token = "bot_token"


# python-telegram-bot setup
application = ApplicationBuilder().token(bot_token).build()

# python-telegram-bot command handler
async def start(update: Update, context: CallbackContext):
    request_chat = KeyboardButtonRequestChat(1, True)
    keyboard = [[KeyboardButton("Request Chat", request_chat=request_chat)]]
    reply_markup = ReplyKeyboardMarkup(keyboard)
    await update.message.reply_text('Please share your contact details', reply_markup=reply_markup)



async def request_contact(update: Update, context: CallbackContext):
    chat = await update.chat_shared
    print(chat.id)


application.add_handler(CommandHandler('start', start))
application.add_handler(MessageHandler(filters._Contact, request_contact)) #here is the problem!

# Running both libraries
print('Running...')
application.run_polling()

在我运行机器人、调用 \start 命令并分享聊天后，我遇到了这个错误：

No error handlers are registered, logging exception.
Traceback (most recent call last):
  File "/home/amin/anaconda3/envs/telegramBot/lib/python3.11/site-packages/telegram/ext/_application.py", line 1099, in process_update
    check = handler.check_update(update)  # Should the handler handle this update?
            ^^^^^^^^^^^^^^^^^^^^^^^^^^^^
  File "/home/amin/anaconda3/envs/telegramBot/lib/python3.11/site-packages/telegram/ext/_messagehandler.py", line 99, in check_update
    return self.filters.check_update(update) or False
           ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
TypeError: MessageFilter.check_update() missing 1 required positional argument: 'update'

Answer 1

您使用了

filters._Contact

，它是

filters

模块的受保护类。这些不是供用户使用的，而是供

python-telegram-bot

库本身内部使用的。另见PEP8。 请选择 here 中记录的过滤器之一。我想你会想要使用

filters.StatusUpdate.CHAT_SHARED

.
