Mais vous pouvez retourner une `JSONResponse` directement à partir de vos *opérations de chemin*.

Cela peut être utile, par exemple, pour retourner des en-têtes personnalisés ou des cookies.

## Renvoyer une `Response`

En fait, vous pouvez retourner n'importe quelle `Response` ou n'importe quelle sous-classe de celle-ci.

MinIO server supports storage class in erasure coding mode. This allows configurable data and parity drives per object.

This page is intended as a summary of MinIO Erasure Coding. For a more complete explanation, see <https://min.io/docs/minio/linux/operations/concepts/erasure-coding.html>.

## Overview

MinIO supports two storage classes, Reduced Redundancy class and Standard class. These classes can be defined using environment variables

`@lru_cache` is part of `functools` which is part of Python's standard library, you can read more about it in the <a href="https://docs.python.org/3/library/functools.html#functools.lru_cache" class="external-link" target="_blank">Python docs for `@lru_cache`</a>.

## Recap

You can use Pydantic Settings to handle the settings or configurations for your application, with all the power of Pydantic models.

**FastAPI** 使用 Python 类型声明实现了数据校验。

注意，上面的错误清晰地指出了未通过校验的具体原因。

这在开发调试与 API 交互的代码时非常有用。

还是使用 Python 类型声明，**FastAPI** 提供了（集成 Swagger UI 的）API 文档。

注意，路径参数的类型是整数。
