Par exemple, pour déclarer une autre réponse avec un code HTTP `404` et un modèle Pydantic `Message`, vous pouvez écrire :

```Python hl_lines="18 22"
{!../../docs_src/additional_responses/tutorial001.py!}
```

/// note | "Remarque"

Gardez à l'esprit que vous devez renvoyer directement `JSONResponse`.

La clé `model` ne fait pas partie d'OpenAPI.

   * ```
   *
   * The caller may read the response body with the response's [Response.body] method. To avoid
   * leaking resources callers must [close the response body][ResponseBody] or the response.
   *
   * Note that transport-layer success (receiving a HTTP response code, headers and body) does not
   * necessarily indicate application-layer success: `response` may still indicate an unhappy HTTP
   * response code like 404 or 500.

`from starlette.staticfiles import StaticFiles` も使用できます。

**FastAPI**は、開発者の利便性のために、`starlette.staticfiles` と同じ `fastapi.staticfiles` を提供します。しかし、実際にはStarletteから直接渡されています。

### 「マウント」とは

/// info | "Informação"

O objeto `app.webhooks` é na verdade apenas um `APIRouter`, o mesmo tipo que você utilizaria ao estruturar a sua aplicação com diversos arquivos.

///

Para esses casos, você pode usar o `jsonable_encoder` para converter seus dados antes de repassá-los para a resposta:

```Python hl_lines="6-7  21-22"
{!../../docs_src/response_directly/tutorial001.py!}
```

/// note | Detalhes Técnicos

Você também pode utilizar `from starlette.responses import JSONResponse`.

Note that, much like [dependencies in *path operation decorators*](dependencies/dependencies-in-path-operation-decorators.md){.internal-link target=_blank}, no value will be passed to your *path operation function*.
