python socket编程7 - 使用PyQt6 开发UI界面新增实现UDP server和client单机通讯的例子

2023-12-13 04:11:21

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

在这里插入图片描述

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

在这里插入图片描述

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

在这里插入图片描述

3、server 完整代码

import sys
from module.main import MainWindow
from PyQt6.QtWidgets import QApplication

if __name__ == '__main__':
    app = QApplication(sys.argv)
