通过电报机器人设置聊天权限

Question

我想向机器人“更改聊天权限”添加一个功能，但我不知道该怎么做。 使用带有 postgresql 数据库的 aiogram 库 (psycopg2)

Python 3.9.5
等距图==2.14.3

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

字典（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

如果我删除更改类 # curSettings = type('types.ChatPermissions', (type,), (curSettings)) 的行，这里是日志：

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

Answer 1

我无法测试它，但基于 telegram-bot issues Append/Update on ChatPermissions 你应该这样做

curSettings = ChatPermissions(**curSettings)
