Для таких случаев вы можете использовать параметр `Response`.

## Использование параметра `Response`

Вы можете объявить параметр типа `Response` в вашей *функции обработки пути* (так же как для cookies и headers).

И затем вы можете установить `status_code` в этом *временном* объекте ответа.

{* ../../docs_src/response_change_status_code/tutorial001.py hl[1,9,12] *}

In diesen Fällen können Sie einen `Response`-Parameter verwenden.

## Einen `Response`-Parameter verwenden

Sie können einen Parameter vom Typ `Response` in Ihrer *Pfadoperation-Funktion* deklarieren (wie Sie es auch für Cookies und Header tun können).

Anschließend können Sie den `status_code` in diesem *vorübergehenden* Response-Objekt festlegen.

{* ../../docs_src/response_change_status_code/tutorial001.py hl[1,9,12] *}

    options:
        members:
            - scope
            - app
            - url
            - base_url
            - headers
            - query_params
            - path_params
            - cookies
            - client
            - state
            - url_for
            - client_state
            - application_state
            - receive
            - send
            - accept

## Curingas

É possível declarar uma lista com `"*"` (um "curinga") para dizer que tudo está permitido.

Mas isso só permitirá certos tipos de comunicação, excluindo tudo que envolva credenciais: cookies, cabeçalhos de autorização como aqueles usados ​​com Bearer Tokens, etc.

Então, para que tudo funcione corretamente, é melhor especificar explicitamente as origens permitidas.

## Usar `CORSMiddleware`

  /**
   * Configure the ApplicationContext. Not needed unless the AndroidX Startup [Initializer] is disabled, or running
   * a robolectric test.
   *
   * The functionality that will fail without a valid Context is primarily Cookies and URL Domain handling, but
   * may expand in the future.
   */
  fun initialize(applicationContext: Context) {
    if (PlatformRegistry.applicationContext == null) {

# `Response` class

You can declare a parameter in a *path operation function* or dependency to be of type `Response` and then you can set data for the response like headers or cookies.

You can also use it directly to create an instance of it and return it from your *path operations*.

You can import it directly from `fastapi`:

```python
from fastapi import Response
```

## Wildcards { #wildcards }

It's also possible to declare the list as `"*"` (a "wildcard") to say that all are allowed.

But that will only allow certain types of communication, excluding everything that involves credentials: Cookies, Authorization headers like those used with Bearer Tokens, etc.

So, for everything to work correctly, it's better to specify explicitly the allowed origins.

## Use `CORSMiddleware` { #use-corsmiddleware }

* Clés d'API dans:
    * Le header.
    * Les paramètres de requêtes.
    * Les cookies, etc.

Plus toutes les fonctionnalités de sécurités venant de Starlette (incluant les **cookies de sessions**).

Le tout conçu en composant réutilisable facilement intégrable à vos systèmes, data stores, base de données relationnelle ou NoSQL, etc.

* Se você precisar enviar *Dados de Formulário* em vez de JSON, use o parâmetro `data`.
* Para passar *headers*, use um `dict` no parâmetro `headers`.
* Para *cookies*, um `dict` no parâmetro `cookies`.

Para mais informações sobre como passar dados para o backend (usando `httpx` ou `TestClient`), consulte a <a href="https://www.python-httpx.org" class="external-link" target="_blank">documentação do HTTPX</a>.

```

## Resumen

Puedes usar **modelos de Pydantic** para declarar **parámetros query** en **FastAPI**. 😎

Alerta de spoiler: también puedes usar modelos de Pydantic para declarar cookies y headers, pero leerás sobre eso más adelante en el tutorial. 🤫
