Zum Beispiel haben wir, das Team hinter FastAPI, <a href="https://fastapicloud.com" class="external-link" target="_blank">**FastAPI Cloud**</a> entwickelt, um das Deployment von FastAPI-Apps in der Cloud so reibungslos wie möglich zu gestalten, mit derselben Developer-Experience wie beim Arbeiten mit FastAPI.

Um das zu tun, verwenden Sie den Standard-Python-Typhinweis <a href="https://docs.python.org/3/library/typing.html#typing.Union" class="external-link" target="_blank">`typing.Union`</a>:

/// note | Hinweis

Для этого используйте стандартную аннотацию типов в Python <a href="https://docs.python.org/3/library/typing.html#typing.Union" class="external-link" target="_blank">`typing.Union`</a>:

Um hochgeladene Dateien und/oder Formulardaten zu empfangen, installieren Sie zuerst <a href="https://github.com/Kludex/python-multipart" class="external-link" target="_blank">`python-multipart`</a>.

Stellen Sie sicher, dass Sie eine [virtuelle Umgebung](../virtual-environments.md){.internal-link target=_blank} erstellen, diese aktivieren und es dann installieren, z. B.:

```console
$ pip install python-multipart
```

For example, let's add <a href="https://github.com/Rebilly/ReDoc/blob/master/docs/redoc-vendor-extensions.md#x-logo" class="external-link" target="_blank">ReDoc's OpenAPI extension to include a custom logo</a>.

### Normal **FastAPI** { #normal-fastapi }

First, write all your **FastAPI** application as normally:

    * 파이썬의 `datetime.timedelta`.
    * 요청과 응답에서 전체 초(seconds)의 `float`로 표현됩니다.
    * Pydantic은 "ISO 8601 시차 인코딩"으로 표현하는 것 또한 허용합니다. <a href="https://docs.pydantic.dev/latest/concepts/serialization/#json_encoders" class="external-link" target="_blank">더 많은 정보는 이 문서에서 확인하십시오.</a>.
* `frozenset`:
    * 요청과 응답에서 `set`와 동일하게 취급됩니다:
        * 요청 시, 리스트를 읽어 중복을 제거하고 `set`로 변환합니다.
        * 응답 시, `set`는 `list`로 변환됩니다.
