これによりFastAPIはレスポンスモデル生成をスキップし、FastAPIアプリケーションに影響させずに必要な戻り値の型アノテーションを付けられます。🤓

## レスポンスモデルのエンコーディングパラメータ { #response-model-encoding-parameters }

レスポンスモデルには次のようにデフォルト値を設定できます:

{* ../../docs_src/response_model/tutorial004_py310.py hl[9,11:12] *}

* `description: Union[str, None] = None`（またはPython 3.10では `str | None = None`）はデフォルトが `None` です。

 * exposes at least one public static final constant of the same type, one of the constants will be
 * used; or if the class exposes a public parameter-less constructor then it will be "new"d and
 * returned.
 *
 * <p>All default instances returned by {@link #get} are generics-safe. Clients won't get type

 *       for implementors</a>

///

La variable `oauth2_scheme` es una instance de `OAuth2PasswordBearer`, pero también es un "callable".

Podría ser llamada como:

```Python
oauth2_scheme(some, parameters)
```

Así que, puede usarse con `Depends`.

### Úsalo { #use-it }

Ahora puedes pasar ese `oauth2_scheme` en una dependencia con `Depends`.
