...this fails because the type annotation is not a Pydantic type and is not just a single `Response` class or subclass, it's a union (any of the two) between a `Response` and a `dict`.

{* ../../docs_src/response_model/tutorial003_04_py310.py hl[8] *}

...isso falha porque a anotação de tipo não é um tipo Pydantic e não é apenas uma única classe ou subclasse `Response`, é uma união (qualquer uma das duas) entre um `Response` e ​​um `dict`.

{* ../../docs_src/response_model/tutorial003_04_py310.py hl[8] *}

...это не сработает, потому что аннотация типа не является типом Pydantic и это не единственный класс `Response` или его подкласс, а объединение (`union`) из `Response` и `dict`.

{* ../../docs_src/response_model/tutorial003_04_py310.py hl[8] *}

... das scheitert, da die Typannotation kein Pydantic-Typ ist, und auch keine einzelne `Response`-Klasse, oder -Unterklasse, es ist eine Union (eines von beiden) von `Response` und `dict`.

{* ../../docs_src/response_model/tutorial003_04_py310.py hl[8] *}

...esto falla porque la anotación de tipo no es un tipo de Pydantic y no es solo una sola clase `Response` o subclase, es una unión (cualquiera de los dos) entre una `Response` y un `dict`.

### `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`.
* El `password`.
