## `Union` 或 `anyOf` { #union-or-anyof }

你可以將回應宣告為多個型別的 `Union`，表示回應可能是其中任一型別。

在 OpenAPI 中會以 `anyOf` 定義。

要達成這點，使用標準的 Python 型別提示 [`typing.Union`](https://docs.python.org/3/library/typing.html#typing.Union)：

/// note

在定義 [`Union`](https://docs.pydantic.dev/latest/concepts/types/#unions) 時，請先放置「更具體」的型別，再放「較不具體」的型別。以下範例中，較具體的 `PlaneItem` 置於 `CarItem` 之前：`Union[PlaneItem, CarItem]`。
