通过电报bot设置聊天权限

Question

我想添加一个功能到机器人“更改聊天权限”，我不知道如何做到这一点。在postgresql数据库(psycopg2)中使用aiogram库

Python 3.9.5

aiogram==2.14.3

回调处理程序(例如: call.data = "defaultchat-can_send_media_messages")

@dp.callback_query_handler(lambda call: "defaultchat" == call.data.split('-')[0])
async def deafultChatCallbacks(call: types.callback_query):
    chatLang = pg.getChatLang(call.message.chat.id)
    call_data = call.data.split('-')[1]
    curSettings = pg.getChatSettings(call.message.chat.id) # :rtype: dict (in db it's json)

    curSettings[call_data] = not curSettings[call_data]
    
    # Trying change the type from dict to types.ChatPermissions
    curSettings = type('types.ChatPermissions', (type,), (curSettings))
    return await call.message.chat.set_permissions(permissions=curSettings)

Dict (或数据库中的json )：

{
    'can_send_messages': True, 
    'can_send_media_messages': True, 
    'can_send_polls': True, 
    'can_send_other_messages': True, 
    'can_add_web_page_previews': True, 
    'can_change_info': True, 
    'can_invite_users': True, 
    'can_pin_messages': True
}

日志：

ERROR:asyncio:Task exception was never retrieved
future: <Task finished name='Task-10' coro=<Dispatcher._process_polling_updates() done, defined at D:\Program Files\Python\lib\site-packages\aiogram\dispatcher\dispatcher.py:409> exception=BadRequest("Can't parse permissions json object")>
...
aiogram.utils.exceptions.BadRequest: Can't parse permissions json object

如果我删除了更改类# curSettings = type('types.ChatPermissions', (type,), (curSettings))的行，下面是日志：

ERROR:asyncio:Task exception was never retrieved
future: <Task finished name='Task-10' coro=<Dispatcher._process_polling_updates() done, defined at D:\Program Files\Python\lib\site-packages\aiogram\dispatcher\dispatcher.py:409> exception=BadRequest('Chat_not_modified')>
...
aiogram.utils.exceptions.BadRequest: Chat_not_modified

我不能测试它，但是基于telegram-bot issues 在ChatPermissions上追加/更新，您应该这样做

curSettings = ChatPermissions(**curSettings)
