The important thing to keep in mind is that the `sub` key should have a unique identifier across the entire application, and it should be a string.

この場合でも各 operation ID が**一意**であることは別の方法で保証する必要があります。

例えば、各 *path operation* にタグを付け、**タグ**と *path operation* の**名前**（関数名）から operation ID を生成できます。

### 一意 ID 生成関数のカスタマイズ { #custom-generate-unique-id-function }

FastAPI は各 *path operation* に**一意 ID**を用いており、これは **operation ID** のほか、必要に応じてリクエストやレスポンスのカスタムモデル名にも使われます。

この関数はカスタマイズ可能です。`APIRoute` を受け取り、文字列を返します。

	// Total object size.
	Size int64

	// Actual size is the real size of the object uploaded by client.
	ActualSize *int64

	// IsDir indicates if the object is prefix.
	IsDir bool

	// Hex encoded unique entity tag of the object.
	ETag string

	// Version ID of this object.
	VersionID string

	// IsLatest indicates if this is the latest current version
	// latest can be true for delete marker or a version.

> NOTE: if *path_prefix* is set then MinIO will not federate your buckets, namespaced IAM assets are assumed as isolated tenants, only buckets are considered globally unique but performing a lookup with a *bucket* which belongs to a different tenant will fail unlike federated setups where MinIO would port-forward and route the request to relevant cluster accordingly. This is a special feature, federated deployments should...
