 * DFS referrals. (E.g. a resource with a DFS root's parent will still point to the DFS root not the share it's actually
 * located in).
 * - share + uncpath within it: This is the relevant information for most SMB requests. Both are adjusted by DFS
 * referrals. Nested resources will inherit the information already resolved by the parent resource.

 * Invariant:

- Kubeadm: make sure that a variety of API server requests are retried during "init", "join", "upgrade", "reset" workflows. Prior to this change some API server requests, such as, creating or updating ConfigMaps were "one-shot"...

Kembali ke kode contoh sebelumnya, **FastAPI** akan:

* Validasi apakah terdapat `item_id` di *path* untuk permintaan `GET` dan `PUT` requests.
* Validasi apakah `item_id` berjenit `int` untuk permintaan `GET` dan `PUT`.
    * Jika tidak, klien akan melihat pesan kesalahan jelas.

そのため、HTTPステータスコードが`418`で、JSONの内容が以下のような明確なエラーを受け取ることになります:

```JSON
{"message": "Oops! yolo did something. There goes a rainbow..."}
```

/// note | 技術詳細

また、`from starlette.requests import Request`と`from starlette.responses import JSONResponse`を使用することもできます。

**FastAPI** は開発者の利便性を考慮して、`fastapi.responses`と同じ`starlette.responses`を提供しています。しかし、利用可能なレスポンスのほとんどはStarletteから直接提供されます。これは`Request`と同じです。
