如何用python socketserver.TCPServer创建多客户端聊天室

import socketserver
import threading

class ChatroomHandler(socketserver.BaseRequestHandler):
    def handle(self):
        # 处理客户端连接和请求的逻辑
        pass

class ChatroomHandler(socketserver.BaseRequestHandler):
    clients = {}
    
    def handle(self):
        # 接收客户端连接并保存连接信息
        self.client_id = self.request.getpeername()
        self.clients[self.client_id] = self.request
        
        # 向所有客户端广播新客户端加入的消息
        self.broadcast(f"Client {self.client_id} joined the chatroom.")
        
        while True:
            try:
                # 接收客户端消息
                data = self.request.recv(1024).decode("utf-8")
                if not data:
                    break
                
                # 向所有客户端广播客户端发送的消息
                self.broadcast(f"Client {self.client_id}: {data}")
            
            except ConnectionResetError:
                break
        
        # 客户端断开连接后的处理逻辑
        del self.clients[self.client_id]
        self.broadcast(f"Client {self.client_id} left the chatroom.")
        
    def broadcast(self, message):
        # 向所有客户端广播消息
        for client in self.clients.values():
            client.sendall(message.encode("utf-8"))

class ChatroomServer(socketserver.ThreadingMixIn, socketserver.TCPServer):
    pass

if __name__ == "__main__":
    HOST = "localhost"
    PORT = 8888
    
    # 创建聊天室服务器
    server = ChatroomServer((HOST, PORT), ChatroomHandler)
    
    # 创建一个线程来处理客户端连接
    server_thread = threading.Thread(target=server.serve_forever)
    server_thread.start()
    
    # 主线程逻辑
    while True:
        command = input("Enter 'quit' to stop the server: ")
        if command.strip().lower() == "quit":
            break
    
    # 关闭服务器
    server.shutdown()
    server.server_close()
