## Recapitulando { #recap }

Você pode usar `Field` do Pydantic para declarar validações extras e metadados para atributos do modelo.

## Resumen { #recap }

Puedes utilizar `Field` de Pydantic para declarar validaciones adicionales y metadatos para los atributos del modelo.

And all these thousands of *path operations* can be as small as 3 lines:

{* ../../docs_src/security/tutorial002_an_py310.py hl[30:32] *}

## Recap { #recap }

You can now get the current user directly in your *path operation function*.

We are already halfway there.

```
X-Token: foo
X-Token: bar
```

Ответ был бы таким:

```JSON
{
    "X-Token values": [
        "bar",
        "foo"
    ]
}
```

## Резюме { #recap }

Объявляйте заголовки с помощью `Header`, используя тот же общий шаблон, как при `Query`, `Path` и `Cookie`.

Это не ограничение **FastAPI**, это часть протокола HTTP.

## Резюме { #recap }

You can try it already in the interactive docs:

We are not verifying the validity of the token yet, but that's a start already.

## Recap { #recap }

Esto no es una limitación de **FastAPI**, es parte del protocolo HTTP.

## Recapitulación { #recap }

```JSON
{
    "X-Token values": [
        "bar",
        "foo"
    ]
}
```

## Zusammenfassung { #recap }

Deklarieren Sie Header mit `Header`, wobei Sie dasselbe gängige Muster wie bei `Query`, `Path` und `Cookie` verwenden.

Password: `secret2`

And try to use the operation `GET` with the path `/users/me`.

You will get an "Inactive user" error, like:

```JSON
{
  "detail": "Inactive user"
}
```

## Recap { #recap }

You now have the tools to implement a complete security system based on `username` and `password` for your API.

```
X-Token: foo
X-Token: bar
```

A resposta seria como:

```JSON
{
    "X-Token values": [
        "bar",
        "foo"
    ]
}
```

## Recapitulando { #recap }

Declare cabeçalhos com `Header`, usando o mesmo padrão comum que utiliza-se em `Query`, `Path` e `Cookie`.
