It used custom types in its declarations instead of standard Python types, but it was still a huge step forward.

It also was one of the first frameworks to generate a custom schema declaring the whole API in JSON.

It was not based on a standard like OpenAPI and JSON Schema. So it wouldn't be straightforward to integrate it with other tools, like Swagger UI. But again, it was a very innovative idea.

* Documentation automatique des modèles de données avec <a href="http://json-schema.org/" class="external-link" target="_blank"><strong>JSON Schema</strong></a> (comme OpenAPI est aussi basée sur JSON Schema).
* Conçue avec ces standards après une analyse méticuleuse. Plutôt qu'en rajoutant des surcouches après coup.

#### Überprüfen Sie die `openapi.json`

Falls Sie wissen möchten, wie das rohe OpenAPI-Schema aussieht: FastAPI generiert automatisch ein JSON (Schema) mit den Beschreibungen Ihrer gesamten API.

* Generar definiciones de <a href="https://json-schema.org" class="external-link" target="_blank">JSON Schema</a> para tu modelo, que también puedes usar en cualquier otro lugar si tiene sentido para tu proyecto.
* Esquemas que serán parte del esquema de OpenAPI generado y usados por la <abbr title="User Interfaces">UIs</abbr> de documentación automática.

## Documentación automática

///

## `HTTPSRedirectMiddleware`

Erzwingt, dass alle eingehenden Requests entweder `https` oder `wss` sein müssen.

Alle eingehenden Requests an `http` oder `ws` werden stattdessen an das sichere Schema umgeleitet.

{* ../../docs_src/advanced_middleware/tutorial001.py hl[2,6] *}

## `TrustedHostMiddleware`

    * Upgrade OpenAPI 3.1.0, this uses JSON Schema 2020-12.
    * Upgrade Swagger UI to version 5.x.x, that supports OpenAPI 3.1.0.

    * <a href="https://fastapi.tiangolo.com/features/" class="external-link" target="_blank">**Viele weitere Funktionen**</a>, einschließlich automatischer Validierung, Serialisierung, interaktiver Dokumentation,...

예를 들어, 표준 :term:Python 타입 힌트 <type hints>에 기반하는 것이 이상적이라는 점이 명확했습니다.

또한, 이미 존재하는 표준을 활용하는 것이 가장 좋은 접근법이라 판단했습니다.

그래서 **FastAPI**의 코드를 작성하기 전에 몇 달 동안 OpenAPI, JSON Schema, OAuth2 명세를 연구하며 이들의 관계와 겹치는 부분, 차이점을 이해했습니다.

## 디자인

그 후, **FastAPI** 사용자가 될 개발자로서 사용하고 싶은 개발자 "API"를 디자인했습니다.

* Modelo de documentação automática com <a href="https://json-schema.org/" class="external-link" target="_blank"><strong>JSON Schema</strong></a> (já que o OpenAPI em si é baseado no JSON Schema).
* Projetado em cima desses padrões após um estudo meticuloso, em vez de uma reflexão breve.
