基于Python guI的多人聊天室的设计与实现

由于原代码较长，以下是一个简化版本的聊天室服务器代码实例，展示了如何使用Python的socket和threading库来创建一个基本的多人聊天室服务器。

import socket
import threading
 
# 聊天室服务器
class ChatServer:
    def __init__(self, host, port):
        self.server_socket = socket.socket(socket.AF_INET, socket.SOCK_STREAM)
        self.server_socket.setsockopt(socket.SOL_SOCKET, socket.SO_REUSEADDR, 1)
        self.server_socket.bind((host, port))
        self.server_socket.listen(5)
        print(f"Chat server started on {host}:{port}")
 
        self.clients = []
 
    def broadcast(self, message, sender_name):
        for client in self.clients:
            if client != sender_name:
                client.send(f"{sender_name} says: {message}".encode('utf-8'))
 
    def start_listening(self):
        while True:
            client_socket, address = self.server_socket.accept()
            client_name = client_socket.recv(1024).decode('utf-8')
            print(f"{client_name} has joined the chat")
 
            client_socket.send(f"Welcome to the chat, {client_name}".encode('utf-8'))
            self.broadcast(f"{client_name} has joined the chat", client_name)
 
            self.clients.append(client_name)
 
            client_thread = threading.Thread(target=self.listen_to_client, args=(client_socket, client_name))
            client_thread.start()
 
    def listen_to_client(self, client_socket, client_name):
        while True:
            try:
                message = client_socket.recv(1024).decode('utf-8')
                if message == 'exit':
                    self.clients.remove(client_name)
                    client_socket.close()
                    break
                self.broadcast(message, client_name)
            except ConnectionResetError:
                self.clients.remove(client_name)
                client_socket.close()
                self.broadcast(f"{client_name} has left the chat", client_name)
                break
 
# 运行服务器
if __name__ == "__main__":
    host = '127.0.0.1'
    port = 8080
    server = ChatServer(host, port)
    server.start_listening()

这段代码创建了一个简单的聊天室服务器，它能够接受多个客户端的连接，并将消息广播给所有在线的客户端。服务器使用socket库来处理网络通信，并使用threading库来为每个客户端启动一个新线程，以便消息的接收和发送可以并行进行。这个简化版本的服务器没有实现图形用户界面，但它展示了服务器端的核心逻辑。
