# Obtener Usuario Actual { #get-current-user }

En el capítulo anterior, el sistema de seguridad (que se basa en el sistema de inyección de dependencias) le estaba dando a la *path operation function* un `token` como un `str`:

{* ../../docs_src/security/tutorial001_an_py39.py hl[12] *}

Pero eso aún no es tan útil. Vamos a hacer que nos dé el usuario actual.

## Crear un modelo de usuario { #create-a-user-model }

 *
 * <h3>String utilities</h3>
 *
 * <ul>
 *   <li>{@link Ascii}
 *   <li>{@link CaseFormat}
 *   <li>{@link CharMatcher}
 *   <li>{@link Splitter}
 *   <li>{@link Strings}
 * </ul>
 *
 * <h3>Function types</h3>
 *
 * <ul>
 *   <li>{@link Converter}
 *   <li>{@link Equivalence}
 * </ul>
 *
 * <h3>Other</h3>
 *
 * <ul>
 *   <li>{@link Enums}
 *   <li>{@link MoreObjects}

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*.

{* ../../docs_src/response_change_status_code/tutorial001_py39.py hl[1,9,12] *}

In that case, they will be applied to all the *path operations* in the application:

And all the ideas in the section about [adding `dependencies` to the *path operation decorators*](dependencies-in-path-operation-decorators.md){.internal-link target=_blank} still apply, but in this case, to all of the *path operations* in the app.
