Para esos casos, puedes usar un parámetro `Response`.

## Usa un parámetro `Response` { #use-a-response-parameter }

Puedes declarar un parámetro de tipo `Response` en tu *path operation function* (como puedes hacer para cookies y headers).

Y luego puedes establecer el `status_code` en ese objeto de response *temporal*.

    Create an invoice.

    This will (let's imagine) let the API user (some external developer) create an
    invoice.

    And this path operation will:

    * Send the invoice to the client.
    * Collect the money from the client.
    * Send a notification back to the API user (the external developer), as a callback.

## `yield`を持つデータベースの依存関係

例えば、これを使ってデータベースセッションを作成し、終了後にそれを閉じることができます。

レスポンスを送信する前に`yield`文を含む前のコードのみが実行されます。

生成された値は、*path operations*や他の依存関係に注入されるものです:

### *Operações de Rota* com `APIRouter` { #path-operations-with-apirouter }

E então você o utiliza para declarar suas *operações de rota*.

Utilize-o da mesma maneira que utilizaria a classe  `FastAPI`:
