Sie können beispielsweise eine Unterklasse von `HTTPBearer` erstellen, die einen Fehler `403 Forbidden` zurückgibt, statt des Default-`401 Unauthorized`-Fehlers:

{* ../../docs_src/authentication_error_status_code/tutorial001_an_py310.py hl[9:13] *}

/// tip | Tipp

Beachten Sie, dass die Funktion die Exception-Instanz zurückgibt; sie wirft sie nicht. Das Werfen erfolgt im restlichen internen Code.

        with:
          limit-access-to-actor: true
        env:
          GITHUB_TOKEN: ${{ secrets.FASTAPI_PR_TOKEN }}
      - name: FastAPI People Contributors
        run: uv run ./scripts/contributors.py
        env:

        with:
          limit-access-to-actor: true
      - name: FastAPI People Sponsors
        run: uv run ./scripts/sponsors.py
        env:
          SPONSORS_TOKEN: ${{ secrets.SPONSORS_TOKEN }}

Bu durumda, uygulamadaki tüm *path operation*'lara uygulanırlar:

{* ../../docs_src/dependencies/tutorial012_an_py310.py hl[17] *}


Ve [*path operation decorator*'larına `dependencies` ekleme](dependencies-in-path-operation-decorators.md) bölümündeki tüm fikirler hâlâ geçerlidir; ancak bu sefer, uygulamadaki tüm *path operation*'lar için geçerli olur.

## `Response` パラメータを使う { #use-a-response-parameter }

*path operation 関数*で `Response` 型のパラメータを宣言できます。

そして、その*一時的*なレスポンスオブジェクトに Cookie を設定できます。

{* ../../docs_src/response_cookies/tutorial002_py310.py hl[1, 8:9] *}

その後は通常どおり、必要な任意のオブジェクト（`dict`、データベースモデルなど）を返せます。

`response_model` を宣言している場合でも、返したオブジェクトは引き続きフィルタおよび変換されます。

             Searching for package file structure from directories with
             <font color="#3465A4">__init__.py</font> files

Örneğin, varsayılan `401 Unauthorized` hatası yerine `403 Forbidden` hatası döndüren bir `HTTPBearer` alt sınıfı oluşturabilirsiniz:

{* ../../docs_src/authentication_error_status_code/tutorial001_an_py310.py hl[9:13] *}

Fonksiyonun exception instance'ını döndürdüğüne dikkat edin; exception'ı raise etmiyor. Raise işlemi internal kodun geri kalan kısmında yapılıyor.
