Python Bot Telepot 错误 'raise KeyError('NoSuggested keys %s in %s' % (str(keys), str(d)))'

Question

我已经用 Telepot 12.7 实现了很多电报机器人，从来没有遇到过任何问题。现在，突然，在将我的机器人添加到组后，它开始向垃圾邮件发送此错误消息：

    raise KeyError('No suggested keys %s in %s' % (str(keys), str(d)))
KeyError: "No suggested keys ['message', 'edited_message', 'channel_post', 'edited_channel_post', 'callback_query', 'inline_query', 'chosen_inline_result', 'shipping_query', 'pre_checkout_query'] in {'update_id': 676740400, 'my_chat_member': {'chat': {'id': -500413139, 'title': 'NazTestGroup', 'type': 'group', 'all_members_are_administrators': True}, 'from': {'id': 172579176, 'is_bot': False, 'first_name': 'Nazareno Descanso', 'username': 'Descanso7', 'language_code': 'en'}, 'date': 1616661428, 'old_chat_member': {'user': {'id': 1684936782, 'is_bot': True, 'first_name': 'telegram-reputation', 'username': 'reputationhmci_bot'}, 'status': 'member'}, 'new_chat_member': {'user': {'id': 1684936782, 'is_bot': True, 'first_name': 'telegram-reputation', 'username': 'reputationhmci_bot'}, 'status': 'left'}}}"

问题似乎是这样的：https://github.com/nickoala/telepot/issues/184 但这是 2016 年解决的老问题。 我尝试将“new_chat_member”添加到键盘映射中，通过此修复，机器人启动但没有响应，没有任何内容传递给“handle(msg)”方法。如果您在私人聊天中而不是在群组中写信，它会回复。

这是我初始化机器人的代码：

def handle(msg):
    global users_manager

    content_type, chat_type, chat_id = telepot.glance(msg)
    print(content_type, chat_type, chat_id, msg)

    try:
        userid = get_userid(chat_id, msg)
        users_manager.add_user(userid)

        if content_type == "text" and msg["text"] == "/start":
            bot.sendMessage(chat_id, f"Ciao! Sono reputation_bot, vi darò punti per ogni messaggio scritto "
                                     f"potendo guadagnare così livelli esclusivi!")
        else:
                users_manager.get_user(userid).add_points(1)
                check_if_lucky_message(userid, chat_id, msg)
                check_current_level(userid, chat_id, msg)
                print(users_manager.get_user(userid))
                pickle.dump(users_manager, open("score_dict.pkl", mode="wb"))
    except Exception as e:
        print(f"Error:: {e}")
      

def main(argv):

    global bot
    global users_manager
    global levels_manager

    print(f"Bot started, token {TOKEN}")
    bot = telepot.Bot(TOKEN)

    levels_manager = LevelManager()
    users_manager = pickle.load(open("score_dict.pkl", mode="rb")) \
        if os.path.exists("score_dict.pkl") else UsersManager()

    print(levels_manager)
    print(users_manager)

    bot.message_loop(handle, run_forever=True)


if __name__ == "__main__":
    main(sys.argv[1:])

面临同样的问题：

Traceback (most recent call last):
  File "C:\Program Files\Python37\lib\site-packages\telepot\aio\loop.py", line 38, in run_forever
    self._update_handler(update)
  File "C:\Program Files\Python37\lib\site-packages\telepot\aio\loop.py", line 82, in <lambda>
    self._handle(_extract_message(update)[1]))
  File "C:\Program Files\Python37\lib\site-packages\telepot\loop.py", line 111, in _extract_message
    'pre_checkout_query'])
  File "C:\Program Files\Python37\lib\site-packages\telepot\__init__.py", line 68, in _find_first_key
    raise KeyError('No suggested keys %s in %s' % (str(keys), str(d))

)

环境：

Python 3.7.7

telepot==12.7

尝试：

使用@Carlog 为我提出的建议例外：

Traceback (most recent call last):
  File "C:\Program Files\Python37\lib\site-packages\telepot\aio\loop.py", line 38, in run_forever
    self._update_handler(update)
  File "C:\Program Files\Python37\lib\site-packages\telepot\aio\loop.py", line 82, in <lambda>
    self._handle(_extract_message(update)[1]))
  File "C:\Program Files\Python37\lib\site-packages\telepot\aio\__init__.py", line 912, in handle
    id = calculate_seed(msg)
  File "C:\Program Files\Python37\lib\site-packages\telepot\delegate.py", line 303, in f
    seed = fn(msg)
  File "C:\Program Files\Python37\lib\site-packages\telepot\delegate.py", line 9, in w
    return fn(*args, **kwargs)
  File "C:\Program Files\Python37\lib\site-packages\telepot\delegate.py", line 24, in <lambda>
    if types == 'all' or msg['chat']['type'] in types
TypeError: 'int' object is not subscriptable

这是我们的机器人的hotfix，直到我们有更好的解决方案。

在文件 Lib\site-packages\telepot\loop.py 中更改函数 _extract_message。

def _extract_message(update):

    key = _find_first_key(update, ['update_id',
                                   'message',
                                   'edited_message',
                                   'channel_post',
                                   'edited_channel_post',
                                   'callback_query',
                                   'inline_query',
                                   'chosen_inline_result',
                                   'shipping_query',
                                   'pre_checkout_query'])

    if key != 'update_id':
        return key, update[key]

    if 'message' in update.keys():
        return 'message', update['message']

    if 'my_chat_member' in update.keys():
        return 'message', {'message_id': update['update_id'], 
                            'from': update['my_chat_member']['from'], 
                            'chat': update['my_chat_member']['chat'], 
                            'date': update['my_chat_member']['date'], 
                            'text': f"It's update_id {update['update_id']}"
                        }
    raise Exception('The hotfix for update_id bug needs to upgrade')

Answer 2

当我通过 Bot 添加到组时，我遇到了同样的问题。为了解决这个问题，我在模块“loop.py”的 _extract_message(update) 函数内的键列表中添加了“update_id”，第 102 行。

def _extract_message(update):
    key = _find_first_key(update, ['update_id',
                                   'message',
                                   'edited_message',
                                   'channel_post',
                                   'edited_channel_post',
                                   'callback_query',
                                   'inline_query',
                                   'chosen_inline_result',
                                   'shipping_query',
                                   'pre_checkout_query'])
    return key, update[key]

我再次运行机器人，它停止引发异常。然后我删除我的更改，现在一切正常。

（我知道，这是一个丑陋的解决方法，但至少可以解决这个问题）
