你从不会直接调用这些函数。它们由你的框架（此处为 **FastAPI**）调用。

通过依赖注入系统，你还可以告诉 **FastAPI**，你的*路径操作函数*还“依赖”某些应在*路径操作函数*之前执行的内容，**FastAPI** 会负责执行它并“注入”结果。

“依赖注入”的其他常见术语包括：

* 资源（resources）
* 提供方（providers）
* 服务（services）
* 可注入（injectables）
* 组件（components）

## **FastAPI** 插件 { #fastapi-plug-ins }

可以使用**依赖注入**系统构建集成和“插件”。但实际上，根本**不需要创建“插件”**，因为通过依赖项可以声明无限多的集成与交互，使其可用于*路径操作函数*。

	globalObjectAPI = objLayer
