このようにして、モデル間の違いだけを宣言することができます:

{* ../../docs_src/extra_models/tutorial002.py hl[9,15,16,19,20,23,24] *}

## `Union`または`anyOf`

レスポンスを２つの型の`Union`として宣言することができます。

OpenAPIでは`anyOf`で定義されます。

そのためには、標準的なPythonの型ヒント<a href="https://docs.python.org/3/library/typing.html#typing.Union" class="external-link" target="_blank">`typing.Union`</a>を使用します:

{* ../../docs_src/extra_models/tutorial003.py hl[1,14,15,18,19,20,33] *}

Mas aqui está o ponto principal.

O código relacionado à segurança e à injeção de dependências é escrito apenas uma vez.

E você pode torná-lo tão complexo quanto quiser. E ainda assim, tê-lo escrito apenas uma vez, em um único lugar. Com toda a flexibilidade.

Mas você pode ter milhares de endpoints (*operações de rota*) usando o mesmo sistema de segurança.

#### Using `Union` or `Optional` { #using-union-or-optional }

If you are using a Python version below 3.10, here's a tip from my very **subjective** point of view:

* 🚨 Avoid using `Optional[SomeType]`
* Instead ✨ **use `Union[SomeType, None]`** ✨.
