/// info | Informações Técnicas

`Security` é na verdade uma subclasse de `Depends`, e ele possui apenas um parâmetro extra que veremos depois.

Porém ao utilizar `Security` no lugar de `Depends`, o **FastAPI** saberá que ele pode declarar escopos de segurança, utilizá-los internamente, e documentar a API com o OpenAPI.

## Den aktuellen Benutzer einfügen

Und jetzt können wir wiederum `Depends` mit unserem `get_current_user` in der *Pfadoperation* verwenden:

{* ../../docs_src/security/tutorial002_an_py310.py hl[31] *}

Beachten Sie, dass wir als Typ von `current_user` das Pydantic-Modell `User` deklarieren.

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

## Inject the current user { #inject-the-current-user }

So now we can use the same `Depends` with our `get_current_user` in the *path operation*:

{* ../../docs_src/security/tutorial002_an_py310.py hl[31] *}

Notice that we declare the type of `current_user` as the Pydantic model `User`.

Isso nos ajudará...

## Inyectar al usuario actual

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

{* ../../docs_src/security/tutorial002_an_py310.py hl[31] *}

Ten en cuenta que declaramos el tipo de `current_user` como el modelo de Pydantic `User`.

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

## Внедрение зависимости текущего пользователя

Теперь мы можем использовать тот же `Depends` с нашей зависимостью `get_current_user` в *функции обрабатывающей эндпоинт*:
