这篇文章给大家介绍了“基于Python如何实现商城网站的客户端和商家端”的相关知识，讲解详细，步骤过程清晰，有一定的借鉴学习价值，因此分享给大家做个参考，感兴趣的朋友接下来一起跟随小编看看吧。

简介

本项目使用Python语言编写，实现了顾客端和商家端。

功能

• 店主功能：注册、登录、修改店铺信息、添加商品、删除商品、修改商品、查找商品、查看交易记录。
• 顾客功能：注册、登录、修改收货信息、查找商品、购买商品、查看交易记录、取消订单。
  

商家端

• shopMain.py：编写界面上组件的功能，并通过调用send_data.py向服务器发送相应的请求。
• shop ：存放商家端的界面代码。
• ui1 ：存放商家端的ui文件，使用qtdesigner设计。
• send_data.py 将数据封装成json之后发给服务器。
  

顾客端

• customerMain.py：编写界面上组件的功能，并通过调用send_data.py向服务器发送相应的请求。
• customer ：存放顾客端的界面代码。
• ui1 ：存放顾客端的ui文件，使用qtdesigner设计。
• send_data.py 将数据封装成json之后发给服务器。
  

服务器端

• server.py：主要用来处理商家和顾客发来的请求，并调用mysql_op对数据库进行操作。
• mysql_op.py：处理商家和顾客对数据库的操作。

主要代码
