后端定制：使用 FoodAdvisor 的示例秘诀
¥Backend customization: An examples cookbook using FoodAdvisor
此页面的内容可能尚未与 Strapi 5 完全同步。

本文档的当前部分面向希望更深入了解 Strapi 后端定制可能性的开发者。
¥The present section of the documentation is intended for developers who would like to get a deeper understanding of the Strapi back end customization possibilities.
本节是一系列示例，演示如何在实际项目中使用 Strapi 后端服务器的核心组件。与后端交互的前端代码也可能是某些示例的一部分，但默认情况下显示在折叠块中，因为前端代码示例不是本教程的主要焦点。
¥The section is a collection of examples that demonstrate how the core components of the back-end server of Strapi can be used in a real-world project. Front-end code that interacts with the back end may also be part of some examples, but displayed in collapsed blocks by default since front-end code examples are not the main focus of this cookbook.
示例旨在扩展官方 Strapi 演示应用 FoodAdvisor 的功能。FoodAdvisor 构建了一个由 Strapi 后端（包含在 /api 文件夹中）支持的现成餐厅目录，并渲染了一个由 Next.js 支持的前端网站（包含在 /client 文件夹中）。
¥Examples are meant to extend the features of FoodAdvisor , the official Strapi demo application. FoodAdvisor builds a ready-made restaurants directory powered by a Strapi back end (included in the /api folder) and renders a Next.js -powered front-end website (included in the /client folder).

帮助你使用 内容类型生成器 创建内容结构并通过 内容管理者 添加一些内容，然后通过 API 公开内容。
¥that helps you create a content structure with the Content-Type Builder and add some content through the Content Manager, then exposes the content through APIs.

👀 你已阅读 后端定制介绍 以大致了解 Strapi 中的路由、策略、中间件、控制器和服务。
¥👀 You have read the back-end customization introduction to get a general understanding of what routes, policies, middlewares, controllers, and services are in Strapi.

👷 如果你想自己测试和使用代码示例，请确保你已克隆 FoodAdvisor 存储库，设置项目，并启动前端和后端服务器。Strapi 管理面板应该可以从 `localhost:1337/admin` 访问，并且基于 Next.js 的 FoodAdvisor 前端网站应该在 `localhost:3000` 上运行。
¥👷 If you want to test and play with the code examples by yourself, ensure you have cloned the FoodAdvisor repository, setup the project, and started both the front-end and back-end servers. The Strapi admin panel should be accessible from `localhost:1337/admin` and the Next.js-based FoodAdvisor front-end website should be running on `localhost:3000` .
你可以从头到尾阅读本节，或者你可能想直接跳转到特定页面以了解如何使用 Strapi 后端的给定核心元素来解决实际用例示例：
