基于nodejs+vue微信小程序加油站服务管理系统

**基于Node.js + Vue 的微信小程序加油站服务管理系统**

**系统概述**

本系统是为加油站服务提供的一套管理系统，主要功能包括用户管理、加油记录管理、订单管理等。系统使用 Node.js 和 Vue 构建，前端采用微信小程序开发。

**系统架构**

系统架构如下：

* **后端**: Node.js + Express.js* **前端**: 微信小程序 (Vue)
* **数据库**: MySQL**系统功能**

1. **用户管理**
* 用户注册和登录 * 用户信息管理（修改、删除）
2. **加油记录管理**
* 加油记录添加和编辑 * 加油记录列表展示3. **订单管理**
* 订单添加和编辑 * 订单列表展示**系统实现**

### 后端(Node.js + Express.js)

#### 用户管理
