在 OpenAPI 中可以使用 `anyOf` 定义。

为此，请使用 Python 标准类型提示 <a href="https://docs.python.org/3/library/typing.html#typing.Union" class="external-link" target="_blank">`typing.Union`</a>：

/// note | "笔记"

定义 <a href="https://docs.pydantic.dev/latest/concepts/types/#unions" class="external-link" target="_blank">`Union`</a> 类型时，要把详细的类型写在前面，然后是不太详细的类型。下例中，更详细的 `PlaneItem` 位于 `Union[PlaneItem，CarItem]` 中的 `CarItem` 之前。

 * We strongly suggest that you create an explicit {@link jcifs.context.CIFSContextWrapper}

 * 
 * If you want to retain the classic singleton behavior you can use
 * {@link jcifs.context.SingletonContext#getInstance()}
 * witch is initialized using system properties.
