至此，我们已经使用多种类型声明了请求的各种组件。

并从以下对象中提取数据：

* 路径参数
* 请求头
* Cookies
* 等

**FastAPI** 使用这种方式验证数据、转换数据，并自动生成 API 文档。

但有时，我们也需要直接访问 `Request` 对象。

## `Request` 对象的细节 { #details-about-the-request-object }

实际上，**FastAPI** 的底层是 **Starlette**，**FastAPI** 只不过是在 **Starlette** 顶层提供了一些工具，所以能直接使用 Starlette 的 [`Request`](https://www.starlette.dev/requests/) 对象。

  2. kubectl port-forward $POD_NAME 9000 --namespace {{ .Release.Namespace }}

You can now access MinIO server on http://localhost:9000. Follow the below steps to connect to MinIO server with mc client:
