这是一篇什么文章？ 一篇你对测试开发工作感兴趣，想了解系统工作逻辑的文章。 一篇是你在开始动手搭建环境前需要了解各工具原理的文章。 这是一篇你真正开始前需要查阅的文章。 本文介绍了前后端工作原理，前后端搭建的流程、搭建过程中需要用到的技术以及 开发环境版本。 一、前后端如何工作 Django、Vue 和 Element UI 前后 端原理论述  作者：M&T. 2 《51 测试天地》七十四 www 端负责数据处理和业务 逻辑，通过 API 接口进行数据传输和交互，从而实现一个完整的 Web 应用。 3 《51 测试天地》七十四 www.51testing.com 二、搭建流程 2.1 后端搭建流程 安装相关包->创建工程->后端依赖（pipenv）创建虚拟环境->后端服务配置启动->后 端创建子应用->后端 Rest Framework->数据库配置 简要说明： 安装相关包：在开始之前，首先需要安装 API，方便前端 和其他应用调用后端接口。 数据库配置：配置 Django 项目的数据库连接，通常使用 MySQL 作为后端数据库， 可以在 settings.py 中进行配置。 2.2 前端搭建流程 创建工程（模板）->前端依赖（npm install ）->前端服务配置启动 简要说明： 创建工程（模板）：可以使用 Vue 脚手架工具或其他模板工具来创建 Vue 项目的初始 结构。 前端依赖（npm
