### `OAuth2PasswordRequestForm` { #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`.

Now let's use the utilities provided by **FastAPI** to handle this.

### `OAuth2PasswordRequestForm` { #oauth2passwordrequestform }

First, import `OAuth2PasswordRequestForm`, and use it as a dependency with `Depends` in the *path operation* for `/token`:

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

`OAuth2PasswordRequestForm` is a class dependency that declares a form body with:

* The `username`.

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

### `OAuth2PasswordRequestForm` { #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`.

Na maioria dos casos, você teria (e deveria ter) um "proxy de terminação" tratando o HTTPS por cima; isso dependerá de como você faz o deploy da sua aplicação, seu provedor pode fazer isso por você ou talvez seja necessário que você configure isso por conta própria.
