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 Rest 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，这种前后端分离的开 API 请求，并返回适当的响应。包括基于 函数的视图和基于类的视图，还有通用视图和视图集等。 路由：DRF 提供了灵活的路由功能，用于将 API 请求映射到相应的视图处理函数上。 认证和权限：DRF 支持各种认证和权限控制方式，可以保护 API 的安全性。 分页和过滤：DRF 提供了分页和过滤功能，便于处理大量数据和筛选查询结果。 强大的请求和响应处理：DRF 支持各种数据格式的请求和响应处理，包括
