# Extender OpenAPI { #extending-openapi }

Hay algunos casos en los que podrías necesitar modificar el esquema de OpenAPI generado.

En esta sección verás cómo hacerlo.

## El proceso normal { #the-normal-process }

El proceso normal (por defecto) es el siguiente.

Una aplicación (instance) de `FastAPI` tiene un método `.openapi()` que se espera que devuelva el esquema de OpenAPI.

# OpenAPI erweitern { #extending-openapi }

Es gibt einige Fälle, in denen Sie das generierte OpenAPI-Schema ändern müssen.

In diesem Abschnitt erfahren Sie, wie.

## Der normale Vorgang { #the-normal-process }

Der normale (Standard-)Prozess ist wie folgt.

Eine `FastAPI`-Anwendung (Instanz) verfügt über eine `.openapi()`-Methode, von der erwartet wird, dass sie das OpenAPI-Schema zurückgibt.

import org.lastaflute.web.response.ActionResponse;
import org.lastaflute.web.response.HtmlResponse;
import org.lastaflute.web.response.render.RenderData;

    }

for it.

If we decide to pursue a feature request, it will go through a thorough process
of API design and review. Any code should come after this.

Pull requests
-------------

Puedes añadir código que se ejecute con la `request`, antes de que cualquier *path operation* la reciba.

Y también después de que se genere la `response`, antes de devolverla.

Por ejemplo, podrías añadir un custom header `X-Process-Time` que contenga el tiempo en segundos que tomó procesar la request y generar una response:

{* ../../docs_src/middleware/tutorial001_py39.py hl[10,12:13] *}

### `response`의 전과 후

*경로 작동*을 받기 전 `request`와 함께 작동할 수 있는 코드를 추가할 수 있습니다.

그리고 `response` 또한 생성된 후 반환되기 전에 코드를 추가 할 수 있습니다.

예를 들어, 요청을 수행하고 응답을 생성하는데 까지 걸린 시간 값을 가지고 있는 `X-Process-Time` 같은 사용자 정의 헤더를 추가할 수 있습니다.

{* ../../docs_src/middleware/tutorial001.py hl[10,12:13] *}

## 다른 미들웨어

미들웨어에 대한 더 많은 정보는 [숙련된 사용자 안내서: 향상된 미들웨어](../advanced/middleware.md){.internal-link target=\_blank}에서 확인할 수 있습니다.

Und auch nachdem die `response` generiert wurde, bevor sie zurückgegeben wird.

Sie könnten beispielsweise einen benutzerdefinierten Header `X-Process-Time` hinzufügen, der die Zeit in Sekunden enthält, die benötigt wurde, um den Request zu verarbeiten und eine Response zu generieren:

{* ../../docs_src/middleware/tutorial001_py39.py hl[10,12:13] *}
