我的代碼基本上需要啓動一個簡單的客戶端聊天服務器。服務器和客戶端可以互相交談。我已經得到了一切正確的實施，但我無法弄清楚如何在完成後關閉服務器。 （我知道它是ss.shutdown()）。Python訪問BaseRequestHandler
我想現在基於兩個（類似"bye"）之間共享的關鍵字來結束，但我不知道如果我能以某種方式從BaseRequestHandler發送郵件到我的SocketServer到shutdown()每當它接收到的信息。
最終，我的目標是將Tkinter合併成一個GUI，但我想讓其他所有東西都先工作，這是我第一次在Python中處理套接字。

是啊，我知道設置（）是一個可怕的功能，現在與嘗試的和漁獲物，但它工作了，所以我打算以後解決它。
我的問題基本上是：我怎樣才能讓服務器根據收到的消息真正結束？如果可能，有沒有辦法在啓動後訪問請求處理程序？
