Par exemple, ajoutons [l’extension OpenAPI de ReDoc pour inclure un logo personnalisé](https://github.com/Rebilly/ReDoc/blob/master/docs/redoc-vendor-extensions.md#x-logo).

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

Tout d’abord, écrivez votre application **FastAPI** comme d’habitude :

  `Take off your hat,' the King said to the Hatter.

  `It isn't mine,' said the Hatter.

  `Stolen!' the King exclaimed, turning to the jury, who
instantly made a memorandum of the fact.

  `I keep them to sell,' the Hatter added as an explanation;
`I've none of my own.  I'm a hatter.'

  Here the Queen put on her spectacles, and began staring at the
Hatter, who turned pale and fidgeted.

### L’expression du chemin de callback { #the-callback-path-expression }

* *path*에는 [OpenAPI 3 표현식](https://github.com/OAI/OpenAPI-Specification/blob/master/versions/3.1.0.md#key-expression)(자세한 내용은 아래 참고)이 포함될 수 있으며, 이를 통해 *여러분의 API*로 보내진 원래 요청의 파라미터와 일부 값을 변수로 사용할 수 있습니다.

### 콜백 경로 표현식 { #the-callback-path-expression }

콜백 *path*는 *여러분의 API*로 보내진 원래 요청의 일부를 포함할 수 있는 [OpenAPI 3 표현식](https://github.com/OAI/OpenAPI-Specification/blob/master/versions/3.1.0.md#key-expression)을 가질 수 있습니다.

이 경우, 다음 `str`입니다:

Fügen wir beispielsweise [ReDocs OpenAPI-Erweiterung zum Einbinden eines benutzerdefinierten Logos](https://github.com/Rebilly/ReDoc/blob/master/docs/redoc-vendor-extensions.md#x-logo) hinzu.

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

Schreiben Sie zunächst wie gewohnt Ihre ganze **FastAPI**-Anwendung:

Por ejemplo, vamos a añadir [la extensión OpenAPI de ReDoc para incluir un logo personalizado](https://github.com/Rebilly/ReDoc/blob/master/docs/redoc-vendor-extensions.md#x-logo).

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

Primero, escribe toda tu aplicación **FastAPI** como normalmente:

## Autres middlewares { #other-middlewares }

Il existe de nombreux autres middlewares ASGI.

Par exemple :

- [Le `ProxyHeadersMiddleware` d'Uvicorn](https://github.com/encode/uvicorn/blob/master/uvicorn/middleware/proxy_headers.py)
- [MessagePack](https://github.com/florimondmanca/msgpack-asgi)

///

## 기본값 덮어쓰기 { #overriding-the-defaults }

위 정보를 바탕으로, 동일한 유틸리티 함수를 사용해 OpenAPI 스키마를 생성하고 필요한 각 부분을 덮어쓸 수 있습니다.

예를 들어, [커스텀 로고를 포함하기 위한 ReDoc의 OpenAPI 확장](https://github.com/Rebilly/ReDoc/blob/master/docs/redoc-vendor-extensions.md#x-logo)을 추가해 보겠습니다.

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

먼저, 평소처럼 **FastAPI** 애플리케이션을 모두 작성합니다:
