## Obtener el usuario { #get-the-user }

`get_current_user` usará una función de utilidad (falsa) que creamos, que toma un token como un `str` y devuelve nuestro modelo de Pydantic `User`:

{* ../../docs_src/security/tutorial002_an_py310.py hl[19:22,26:27] *}

## Inyectar al usuario actual { #inject-the-current-user }

Entonces ahora podemos usar el mismo `Depends` con nuestro `get_current_user` en la *path operation*:

## Obter o usuário { #get-the-user }

`get_current_user` usará uma função utilitária (falsa) que criamos, que recebe um token como uma `str` e retorna nosso modelo Pydantic `User`:

{* ../../docs_src/security/tutorial002_an_py310.py hl[19:22,26:27] *}

## Injetar o usuário atual { #inject-the-current-user }

Então agora nós podemos usar o mesmo `Depends` com nosso `get_current_user` na *operação de rota*:

 *   <li>Manages crawl delay settings per user agent</li>
 *   <li>Stores sitemap URLs listed in robots.txt</li>
 * </ul>
 *
 * <p>The class uses case-insensitive pattern matching for user agents and supports
 * wildcard characters (*) in user agent strings. When multiple directives match a user agent,
 * the most specific (longest) match is used.</p>
