# Headers de Respuesta

## Usar un parámetro `Response`

Puedes declarar un parámetro de tipo `Response` en tu *función de operación de path* (de manera similar como se hace con las cookies).

Y entonces, podrás configurar las cookies en ese objeto de response *temporal*.

```Python hl_lines="1  7-8"
{!../../../docs_src/response_headers/tutorial002.py!}
```

from fastapi.testclient import TestClient

from docs_src.configure_swagger_ui.tutorial003 import app

client = TestClient(app)


def test_swagger_ui():
    response = client.get("/docs")
    assert response.status_code == 200, response.text
    assert (
        '"deepLinking": false,' in response.text
    ), "overridden configs should be preserved"
    assert (
        '"deepLinking": true' not in response.text

# Path Operation Configuration

There are several parameters that you can pass to your *path operation decorator* to configure it.

!!! warning
    Notice that these parameters are passed directly to the *path operation decorator*, not to your *path operation function*.

## Response Status Code

You can define the (HTTP) `status_code` to be used in the response of your *path operation*.

You can pass directly the `int` code, like `404`.

# Configure Swagger UI

You can configure some extra <a href="https://swagger.io/docs/open-source-tools/swagger-ui/usage/configuration" class="external-link" target="_blank">Swagger UI parameters</a>.

To configure them, pass the `swagger_ui_parameters` argument when creating the `FastAPI()` app object or to the `get_swagger_ui_html()` function.

`swagger_ui_parameters` receives a dictionary with the configurations passed to Swagger UI directly.

Pour voir un exemple, allez voir les [Générateurs de projets](../project-generation.md){.internal-link target=_blank}, ils incluent tous Celery déjà configuré.

Sie können sie jedoch deaktivieren, indem Sie `syntaxHighlight` auf `False` setzen:

```Python hl_lines="3"
{!../../../docs_src/configure_swagger_ui/tutorial001.py!}
```

... und dann zeigt die Swagger-Oberfläche die Syntaxhervorhebung nicht mehr an:

## Das Theme ändern

**Alerta de Spoiler**: o tutorial - guia do usuário inclui:

* Declaração de **parâmetetros** de diferentes lugares como: **cabeçalhos**, **cookies**, **campos de formulários** e **arquivos**.
* Como configurar **Limitações de Validação** como `maximum_length` ou `regex`.
* Um poderoso e fácil de usar sistema de **<abbr title="também conhecido como componentes, recursos, fornecedores, serviços, injetáveis">Injeção de Dependência</abbr>**.

Verifique como *operações de rota* descontinuadas e não descontinuadas se parecem:
