### OpenAPI

**FastAPI** génère un "schéma" contenant toute votre API dans le standard de définition d'API **OpenAPI**.

#### "Schéma"

Un "schéma" est une définition ou une description de quelque chose. Pas le code qui l'implémente, uniquement une description abstraite.

#### "Schéma" d'API

/// info

OpenAPI 3.1.0 (used since FastAPI 0.99.0) added support for `examples`, which is part of the **JSON Schema** standard.

Before that, it only supported the keyword `example` with a single example. That is still supported by OpenAPI 3.1.0, but is deprecated and is not part of the JSON Schema standard. So you are encouraged to migrate `example` to `examples`. 🤓

You can read more at the end of this page.

### Nur modernes Python { #just-modern-python }

Alles basiert auf Standard-**Python-Typ**deklarationen (dank Pydantic). Es muss keine neue Syntax gelernt werden, nur standardisiertes modernes Python.

/// tip | Tipp

Das ist schlicht Standard-Python, es wird als „Typalias“ bezeichnet und ist eigentlich nicht **FastAPI**-spezifisch.

Da **FastAPI** jedoch auf Standard-Python, einschließlich `Annotated`, basiert, können Sie diesen Trick in Ihrem Code verwenden. 😎

request and credential details for every API call to an external HTTP(S) endpoint and expects an allow/deny response. MinIO is thus able to delegate access management to an external system, and users are able to use a custom solution instead of S3 standard IAM policies.

Latency sensitive applications may notice an increased latency due to a request to the external plugin upon every authenticated request to MinIO. User are advised to provision their infrastructure such that latency and performance...

Es war beispielsweise klar, dass es idealerweise auf Standard-Python-Typhinweisen basieren sollte.

Der beste Ansatz bestand außerdem darin, bereits bestehende Standards zu nutzen.
