```Python
some_variable: PlaneItem | CarItem
```

Pero si ponemos eso en la asignación `response_model=PlaneItem | CarItem` obtendríamos un error, porque Python intentaría realizar una **operación inválida** entre `PlaneItem` y `CarItem` en lugar de interpretar eso como una anotación de tipos.

De la misma manera, puedes declarar responses de listas de objetos.

Você deveria fazer isso depois de adicionar todas as suas *operações de rota*.

WebSocketエンドポイントでは、`fastapi` から以下をインポートして使用できます。

* `Depends`
* `Security`
* `Cookie`
* `Header`
* `Path`
* `Query`

これらは、他のFastAPI エンドポイント/*path operations* の場合と同じように機能します。

これはWebSocketであるため、`HTTPException` を発生させることはあまり意味がありません。代わりに `WebSocketException` を発生させます。

filesystem path), a maliciously created checkpoint might be able to change the
targets of those operations, which could result in arbitrary
read/write/executions.
