Pour voir toutes les options dont vous disposez, consultez [l’aperçu des types de Pydantic](https://docs.pydantic.dev/latest/concepts/types/). Vous verrez quelques exemples au chapitre suivant.

Par exemple, comme dans le modèle `Image` nous avons un champ `url`, nous pouvons le déclarer comme instance de `HttpUrl` de Pydantic au lieu de `str` :

  - Built-in IDP users and their respective service accounts
  - LDAP/AD users and their respective service accounts
  - OpenID/OIDC service accounts

- On versioned buckets, FTP/SFTP only operates on latest objects, if you need to retrieve
  an older version you must use an `S3 API client` such as [`mc`](https://github.com/minio/mc).

- All features currently used by your buckets will work as is without any changes

有時你需要做一些上述參數無法處理的「自訂驗證」。

這種情況下，你可以使用「自訂驗證函式」，它會在一般驗證之後套用（例如先確認值是 `str` 之後）。

你可以在 `Annotated` 中使用 [Pydantic 的 `AfterValidator`](https://docs.pydantic.dev/latest/concepts/validators/#field-after-validator) 來達成。

/// tip | 提示

Pydantic 也有 [`BeforeValidator`](https://docs.pydantic.dev/latest/concepts/validators/#field-before-validator) 等等。🤓
