python使用UDP实现客户端和服务器对话

import socket
# 客户端配置
HOST = 'localhost'
PORT = 12345
# 创建UDP套接字
client_socket = socket.socket(socket.AF_INET, socket.SOCK_DGRAM)
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.sendto(message.encode("utf-8"), (HOST, PORT))  # 注意,在不同操作系统上编码可能不同
    # 接收服务器传回的消息
    data, server_address = client_socket.recvfrom(1024)
    print(f"收到来自{server_address}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UDP套接字
server_socket = socket.socket(socket.AF_INET, socket.SOCK_DGRAM)
# 绑定到地址和端口
server_socket.bind((HOST, PORT))
while True:
    # 接收客户端传来的消息
    data, client_address = server_socket.recvfrom(1024)
    print(f"来自{client_address}的消息：{data.decode('utf-8')}")
    # 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
    server_socket.sendto(message.encode("utf-8"), client_address)
# 关闭套接字
server_socket.close()
