/// info | "Informação"

Para enviar dados, você deve usar utilizar um dos métodos: `POST` (Mais comum), `PUT`, `DELETE` ou `PATCH`.

Aber `OAuth2PasswordRequestForm` ist nur eine Klassenabhängigkeit, die Sie selbst hätten schreiben können, oder Sie hätten `Form`ular-Parameter direkt deklarieren können.

Da es sich jedoch um einen häufigen Anwendungsfall handelt, wird er zur Vereinfachung direkt von **FastAPI** bereitgestellt.

///

### Die Formulardaten verwenden

```Python
commons: CommonQueryParams = Depends(CommonQueryParams)
```

////

O último `CommonQueryParams`, em:

```Python
... Depends(CommonQueryParams)
```

...é o que o **FastAPI** irá realmente usar para saber qual é a dependência.

É a partir dele que o FastAPI irá extrair os parâmetros passados e será o que o FastAPI irá realmente chamar.

---

Nesse caso, o primeiro `CommonQueryParams`, em:

```Python hl_lines="2  10"
{!../../docs_src/custom_response/tutorial009.py!}
```

Você também pode usar o parâmetro `response_class`:

```Python hl_lines="2  8  10"
{!../../docs_src/custom_response/tutorial009b.py!}
```

## Recapitulando

Você pode usar o módulo Pydantic Settings para gerenciar as configurações de sua aplicação, utilizando todo o poder dos modelos Pydantic.

- Utilizar dependências simplifica os testes.
