簡介

本項目使用Python語言編寫，實現了顧客端和商家端。

功能 店主功能：注冊、登錄、修改店鋪信息、添加商品、刪除商品、修改商品、查找商品、查看交易記錄。 顧客功能：注冊、登錄、修改收貨信息、查找商品、購買商品、查看交易記錄、取消訂單。 商家端 shopMain.py：編寫界面上組件的功能，并通過調用send_data.py向服務器發送相應的請求。 shop ：存放商家端的界面代碼。 ui1 ：存放商家端的ui文件，使用qtdesigner設計。 send_data.py 將數據封裝成json之后發給服務器。 顧客端 customerMain.py：編寫界面上組件的功能，并通過調用send_data.py向服務器發送相應的請求。 customer ：存放顧客端的界面代碼。 ui1 ：存放顧客端的ui文件，使用qtdesigner設計。 send_data.py 將數據封裝成json之后發給服務器。 服務器端 server.py：主要用來處理商家和顧客發來的請求，并調用mysql_op對數據庫進行操作。 mysql_op.py：處理商家和顧客對數據庫的操作。主要代碼
