## 特殊的类型和校验

除了普通的单一值类型（如 `str`、`int`、`float` 等）外，你还可以使用从 `str` 继承的更复杂的单一值类型。

要了解所有的可用选项，请查看关于 <a href="https://docs.pydantic.dev/latest/concepts/types/" class="external-link" target="_blank">来自 Pydantic 的外部类型</a> 的文档。你将在下一章节中看到一些示例。

例如，在 `Image` 模型中我们有一个 `url` 字段，我们可以把它声明为 Pydantic 的 `HttpUrl`，而不是 `str`：

![delete](https://raw.githubusercontent.com/minio/minio/master/docs/bucket/versioning/versioning_DELETE_versionEnabled.png)

Now the delete marker becomes the current version of the object. GET requests by default always retrieve the latest stored version. So performing a simple GET object request when the current version is a delete marker would return `404` `The specified key does not exist` as shown below:
