Lassen Sie uns nun die von **FastAPI** bereitgestellten Werkzeuge verwenden, um das zu erledigen.

### `OAuth2PasswordRequestForm`

Importieren Sie zunächst `OAuth2PasswordRequestForm` und verwenden Sie es als Abhängigkeit mit `Depends` in der *Pfadoperation* für `/token`:

{* ../../docs_src/security/tutorial003_an_py310.py hl[4,78] *}

`OAuth2PasswordRequestForm` ist eine Klassenabhängigkeit, die einen Formularbody deklariert mit:

* Dem `username`.

Ahora vamos a usar las utilidades proporcionadas por **FastAPI** para manejar esto.

### `OAuth2PasswordRequestForm`

Primero, importa `OAuth2PasswordRequestForm`, y úsalo como una dependencia con `Depends` en la *path operation* para `/token`:

{* ../../docs_src/security/tutorial003_an_py310.py hl[4,78] *}

`OAuth2PasswordRequestForm` es una dependencia de clase que declara un body de formulario con:

* El `username`.
