Cela fonctionne grâce à **Pydantic**, qui offre une [prise en charge interne des `dataclasses`](https://docs.pydantic.dev/latest/concepts/dataclasses/#use-of-stdlib-dataclasses-with-basemodel).

Ainsi, même avec le code ci‑dessus qui n'emploie pas explicitement Pydantic, FastAPI utilise Pydantic pour convertir ces dataclasses standard en la variante de dataclasses de Pydantic.

Поэтому, чтобы всё работало корректно, лучше явно указывать список разрешённых источников.

## Использование `CORSMiddleware` { #use-corsmiddleware }

Вы можете настроить это в вашем **FastAPI**-приложении, используя `CORSMiddleware`.

* Импортируйте `CORSMiddleware`.
* Создайте список разрешённых источников (в виде строк).

	_, err := objAPI.DeleteObject(ctx, minioMetaBucket, historyFile, ObjectOptions{
		DeletePrefix:       true,
		DeletePrefixObject: true, // use prefix delete on exact object (this is an optimization to avoid fan-out calls)
	})
	return err
}
