《51 测试天地》七十四 www.51testing.com 后端开发（Django+Rest Framework+MySQL）： Django 负责处理 HTTP 请求和响应，以及 URL 路由的配置。它接收来自前端的 HTTP 请求，并根据 URL 将请求分发给相应的视图函数进行处理。 Rest Framework 是 Django 的扩展，用于快速构建 RESTful API 接口。通过 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： 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 测试天地》七十四 www.51testing.com 依赖包，这些依赖包通常存储在 package.json 文件中。 前端服务配置启动：在项目目录下执行 npm run serve 命令，启动前端开发服务器， 可以在浏览器中预览项目。 三、关键技术介绍 1、后端为什么要创建虚拟环境，创建虚拟环境可以达到什么效果？ 隔离项目依赖：通过创建后端虚拟环境，每个项目都拥有独立的 Python 解释器和包
