/// info | Technical Details

`Security` is actually a subclass of `Depends`, and it has just one extra parameter that we'll see later.

But by using `Security` instead of `Depends`, **FastAPI** will know that it can declare security scopes, use them internally, and document the API with OpenAPI.

Es gibt hier in der Dokumentation ein ganzes Kapitel darüber, Sie können es unter [Zusätzliche Responses in OpenAPI](additional-responses.md){.internal-link target=_blank} lesen.

## OpenAPI-Extra { #openapi-extra }

Wenn Sie in Ihrer Anwendung eine *Pfadoperation* deklarieren, generiert **FastAPI** automatisch die relevanten Metadaten dieser *Pfadoperation*, die in das OpenAPI-Schema aufgenommen werden sollen.

## Dataclasses em Estruturas de Dados Aninhadas { #dataclasses-in-nested-data-structures }

Você também pode combinar `dataclasses` com outras anotações de tipo para criar estruturas de dados aninhadas.

Em alguns casos, você ainda pode ter que usar a versão do Pydantic das `dataclasses`. Por exemplo, se você tiver erros com a documentação da API gerada automaticamente.

    hashed_password = user_dict["hashed_password"],
)
```

/// info | Informação

Para uma explicação mais completa de `**user_dict`, verifique [a documentação para **Extra Models**](../extra-models.md#about-user-in-dict){.internal-link target=_blank}.

## Retorne o token { #return-the-token }

A resposta do endpoint `token` deve ser um objeto JSON.
