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.51testing.com 后端开发（Django+Rest Framework+MySQL）： 与前端进行数据交互。 MySQL 是一个关系型数据库，用于存储后端的数据。 前端开发（Vue+Element UI）： Vue 是一种现代的 JavaScript 框架，用于构建用户界面。Vue 提供了丰富的组件和模 块，可以帮助开发者构建交互式的单页面应用（SPA）。 Element UI 是一个基于 Vue 的 UI 组件库，提供了丰富的预定义组件，用于快速搭建 美观的用户界面。 前后端交互： 前后端交互： 后端通过 Django Rest Framework 提供 API 接口，前端通过 Vue 发起 HTTP 请求调用 这些 API 接口。 前端通过 HTTP 请求向后端发送数据请求，后端根据请求进行相应的数据处理，并 返回响应数据给前端。 前端接收到后端返回的数据，并根据数据更新页面展示，实现与用户的交互。 总体而言，这种前后端分离的开发模式有助于实现前后端开发的解耦，使得各自的
