## Origem

Uma origem é a combinação de protocolo (`http`, `https`), domínio (`myapp.com`, `localhost`, `localhost.tiangolo.com`), e porta (`80`, `443`, `8080`).

Então, todos estes são origens diferentes:

## Current Behavior
<!--- If describing a bug, tell us what happens instead of the expected behavior -->
<!--- If suggesting a change/improvement, explain the difference from current behavior -->

## Possible Solution
<!--- Not obligatory, but suggest a fix/reason for the bug, -->
<!--- or ideas how to implement the addition or change -->

## Steps to Reproduce (for bugs)

Você provavelmente leu anteriormente que você pode definir um [Código de Status do Retorno](../tutorial/response-status-code.md){.internal-link target=_blank} padrão.

Porém em alguns casos você precisa retornar um código de status diferente do padrão.

## Caso de uso

Por exemplo, imagine que você deseja retornar um código de status HTTP de "OK" `200` por padrão.

## Tests de performance et rapidité

Lorsque vous vérifiez les tests de performance, il est commun de voir plusieurs outils de différents types comparés comme équivalents.

En particulier, on voit Uvicorn, Starlette et FastAPI comparés (parmi de nombreux autres outils).

Inclui estas configurações padrão:

```Python
{!../../fastapi/openapi/docs.py[ln:7-23]!}
```

Você pode substituir qualquer um deles definindo um valor diferente no argumento `swagger_ui_parameters`.

Por exemplo, para desabilitar `deepLinking` você pode passar essas configurações para `swagger_ui_parameters`:

```Python hl_lines="3"

import java.util.concurrent.Future;
import java.util.concurrent.TimeoutException;
