在第五篇中，简单实现了命令行下的 TCP/UDP server和client的单机通讯。
在第六篇中，实现了PyQt6开发界面，TCP协议实现的单机server和client的通讯功能。
这一篇，在第六篇的基础上，增加了UDP server和client的单机通讯功能。

一、界面

二、对比命令行代码的封装示意

1、UDP Server 界面实现服务配置和数据提供

2、UDP Server封装成2个部分：UDPServer和UDPServerSocketReceiveThread

3、server 完整代码

7、程序启动代码

import sys
from module.main import MainWindow
from PyQt6.QtWidgets import QApplicationif __name__ == '__main__':app = QApplication(sys.argv)login = MainWindow()sys.exit(app.exec())
