《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 数据反序列化为数据对象，便于在后端进行 处理。 视图：DRF 提供了各种视图类，用于处理 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。
