仿qq聊天系统python

C知道: 仿QQ聊天系统，可以使用Python来实现。首先，你可以使用Socket模块来创建一个简单的聊天服务器和客户端。服务器端负责接收客户端的消息并转发给其他客户端，而客户端则负责发送和接收消息。

以下是一个简单的示例代码：

# 服务器端

import socket
import threading

# 创建一个TCP套接字
server_socket = socket.socket(socket.AF_INET, socket.SOCK_STREAM)
server_socket.setsockopt(socket.SOL_SOCKET, socket.SO_REUSEADDR, 1)

# 绑定地址和端口
host = 'localhost'
port = 8888
server_socket.bind((host, port))

# 监听连接
server_socket.listen(5)

# 存储客户端套接字列表
client_sockets = []
client_names = []

def broadcast(message):
    for client_socket in client_sockets:
        client_socket.send(message)

def handle_client(client_socket):
    while True:
        try:
            message = client_socket.recv(1024)
            broadcast(message)
        except:
            index = client_sockets.index(client_socket)
            client_sockets.remove(client_socket)
            client_socket.close()
            username = client_names[index]
            broadcast(f'{username}已下线'.encode('utf-8'))
            client_names.remove(username)
            break

def accept_clients():
    while True:
        client_socket, address = server_socket.accept()
        client_sockets.append(client_socket)
        username = client_socket.recv(1024).decode('utf-8')
        client_names.append(username)
        broadcast(f'{username}已上线'.encode('utf-8'))
        client_socket.send('成功连接到服务器'.encode('utf-8'))
        client_socket.send(f'当前在线用户：{client_names}'.encode('utf-8'))
        client_socket.send('请输入消息：'.encode('utf-8'))
        client_socket_thread = threading.Thread(target=handle_client, args=(client_socket,))
        client_socket_thread.start()

accept_clients()

# 客户端

import socket
import threading

# 创建一个TCP套接字
client_socket = socket.socket(socket.AF_INET, socket.SOCK_STREAM)

# 连接到服务器
host = 'localhost'
port = 8888
client_socket.connect((host, port))

# 输入用户名
username = input('请输入用户名：')
client_socket.send(username.encode('utf-8'))

def receive_messages():
    while True:
        try:
            message = client_socket.recv(1024).decode('utf-8')
            print(message)
        except:
            print('连接已断开')
            break

def send_messages():
    while True:
        message = input()
        client_socket.send(message.encode('utf-8'))

receive_thread = threading.Thread(target=receive_messages)
receive_thread.start()

send_thread = threading.Thread(target=send_messages)
send_thread.start()

这只是一个简单的示例，你可以根据自己的需求进行扩展和修改。希望对你有所帮助！如果有任何问题，可以随时问我。
