查询引擎 API

¥Query Engine API

Strapi 后端提供了一个查询引擎 API 来与更底层的数据库层进行交互。

¥The Strapi backend provides a Query Engine API to interact with the database layer at a lower level.

提醒

在大多数情况下，你不应使用查询引擎 API，而应使用 文档服务 API。

¥In most cases you should not use the Query Engine API and rather use the Document Service API.

仅当你确切知道自己在做什么时才使用查询引擎 API，例如，如果你想使用直接与数据库的唯一行交互的底层 API。

¥Only use the Query Engine API if you exactly know what you are doing, for instance if you want to use a lower-level API that directly interacts with unique rows of the database.

请记住，查询引擎 API 不了解最高级的 Strapi 5 功能，如草稿和发布、国际化、内容历史记录等。

¥Please keep in mind that the Query Engine API is not aware of the most advanced Strapi 5 features like Draft & Publish, Internationalization, Content History, and possibly more.
