本来想着写个前端在线网页扫描飞牛设备，以实现像群晖Synology Web Assistant一样功能，无奈前端限制太多无法实现，于是有了后文前后端结合智谱清言AI写的代码（前端HTML后端Python），打包成一个exe可执行文件。

一、文件结构

lan-scanner-project/
├── main.py         # 后端Python程序
├── index.html      # 前端HTML代码
├── style.css       # 前端样式代码
└── icon.ico        # exe文件图标

将相应文件（夹）创建好备用

二、前端文件

将index.html文件内写入以下内容并保存

五、编译安装

5.1 安装Python

去官网下载安装：https://www.python.org/downloads/windows/

5.2 安装工具

PyInstaller 是Python 应用程序打包成独立可执行文件的工具

pip install pyinstaller

5.3 编译文件

pyinstaller --onefile -n 飞牛扫描工具 --icon=icon.ico --add-data "index.html;." --add-data "style.css;." main.py

六、成品使用

在 dist 文件夹中找到exe文件，双击运行程序，允许通过防火墙，程序会自动打开浏览器访问 http://localhost:15666

选择扫描飞牛默认端口5666，点开始扫描等待即可。
