一、项目简介

(1)系统的通用功能包括用户登录和密码修改，是两个角色共同需要使用的功能，
(2) 管理员关键功能包含用户、设备类型、设备信息、系统管理、订单管理、个人资料等进行管理。
(3)用户可以对个人中心、修改密码、我的订单、我的地址、我的收藏等进行操作。

二、系统设计

2.1软件功能模块设计

系统总体结构图如下，见图4-1。

2.2数据库设计

根据系统需求，将“用户、公告信息、设备信息、配置文件”等作为实体，它们的局部E-R图，如图4-3所示：

三、系统项目部分截图

3.1前台功能实现

系统首页页面
当人们打开系统的网址后，首先看到的就是首页界面。在这里，人们能够看到系统的导航条，通过导航条导航进入各功能展示页面进行操作。系统首页界面如图5-1所示：

设备信息：在设备信息页面的输入栏中输入设备名称或价格进行查询，可以查看到设备详细信息，并进行收藏、添加到购物车、立即购买或评论操作；设备信息页面如图5-3所示：

在注册流程中，用户在Vue前端填写必要信息（如用户名、密码等）并提交。前端将这些信息通过HTTP请求发送到Python后端。后端处理这些信息，检查用户名是否唯一，并将新用户数据存入MySQL数据库。完成后，后端向前端发送注册成功的确认，前端随后通知用户完成注册。这个过程实现了新用户的数据收集、验证和存储。系统注册页面如图5-2所示：

3.2管理员功能实现

管理员进入主页面，主要功能包括对用户、设备类型、设备信息、系统管理、订单管理、个人资料等进行操作。管理员主页面如图5-7所示：

用户管理功能实现是在Django后端部分，您需要创建一个新的应用，然后在该应用下创建一个模型（models.py）来定义学生的数据结构，使用Django的ORM来处理与MySQL数据库的交互，包括用户信息的搜索、新增或删除等操作。接着，在views.py中编写视图逻辑来处理前端请求，使用Django的URL路由（urls.py）将请求映射到相应的视图函数。对于数据的验证和序列化，可以使用Django的表单或序列化器来实现。在前端Vue.js部分，将创建相应的Vue组件，在这些组件中使用axios或其他HTTP库与Django后端的API进行交互，实现用户信息的查看、修改或删除用户等功能。状态管理可以通过Vuex来维护，比如在store目录下定义用户模块的状态、突变、动作和获取器。如图5-8所示：

设备信息功能如图5-10所示：
