................................................................................ 477 Day 9 - 编写 API .................................................................................................. 中文，免费，零起点，完整示例，基于最新的 Python 3 版本。 Python 是一种计算机程序设计语言。你可能已经听说过很多种流行的编 程语言，比如非常难学的 C 语言，非常流行的 Java 语言，适合初学者 的 Basic 语言，适合网页编程的 JavaScript 语言等等。 那 Python 是一种什么语言？ 首先，我们普及一下编程语言的基础知识。用任何编程语言来开发程序， 干同一个活，编写的代码量，差距也很大。 比如，完成同一个任务，C 语言要写 1000 行代码，Java 只需要写 100 行，而 Python 可能只要 20 行。 所以 Python 是一种相当高级的语言。 你也许会问，代码少还不好？代码少的代价是运行速度慢，C 程序运行 1 秒钟，Java 程序可能需要 2 秒，而 Python 程序可能就需要 10 秒。 Python3 基础教程【完整版】

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 Framework，可以定义 API 视图和序列化器，实现数据的序列化和反序列化，从而方便地 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 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： 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。 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 开发工作更加专注和高效。前端负责用户界面的呈现和交互，后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-
