Python에서 TCP를 사용하여 클라이언트와 서버 간의 대화를 구현하는 방법

import socket
# 客户端配置
HOST = 'localhost'
PORT = 12345
# 创建TCP套接字并连接服务器
client_socket = socket.socket(socket.AF_INET, socket.SOCK_STREAM)
client_socket.connect((HOST, PORT))
while True:
    # 获取用户输入
    message = input("请输入要发送的消息：")
    # 发送消息到服务器
    client_socket.sendall(message.encode("utf-8"))
    # 接收服务器传回的消息
    data = client_socket.recv(1024)
    print(f"收到来自服务器的消息：{data.decode('utf-8')}")
# 关闭套接字
client_socket.close()

import socket
# 服务器配置
HOST = 'localhost'
PORT = 12345
# 创建TCP套接字并绑定到地址和端口
server_socket = socket.socket(socket.AF_INET, socket.SOCK_STREAM)
server_socket.bind((HOST, PORT))
# 监听连接
server_socket.listen()
# 接受连接并与客户端建立通信
client_socket, client_address = server_socket.accept()
print(f"与客户端 {client_address} 建立连接。")
while True:
    # 接收客户端传来的消息
    data = client_socket.recv(1024)
    print(f"来自{client_address}的消息：{data.decode('utf-8')}")
    if not data: # 如果客户端关闭了连接，则退出循环 
        break
    # 获取用户输入
    message = input("请输入要发送的消息：")
    # 发送消息到客户端
    client_socket.sendall(message.encode("uft-8"))
# 关闭套接字
client_socket.close()
server_socket.close()
