* **`2XX`** – статус-коды, сообщающие об успешной обработке запроса. Они используются чаще всего.
    * `200` – это код статуса ответа по умолчанию, который означает, что все прошло "OK".
    * Другим примером может быть статус `201`, "Created". Он обычно используется после создания новой записи в базе данных.
    * Особый случай – `204`, "No Content".  Этот статус ответа используется, когда нет содержимого для возврата клиенту, и поэтому ответ не должен иметь тела.

A default retention period and retention mode can be configured on a bucket to be applied to objects created in that bucket. Independent of retention, an object can also be under legal hold. This effectively disallows all deletes of an object under legal hold until the legal hold is removed by an API call.

メインのステータスコードとは別に、他のステータスコードを返したい場合は、`Response` (`JSONResponse` など) に追加のステータスコードを設定して直接返します。

例えば、itemを更新し、成功した場合は200 "OK"のHTTPステータスコードを返す *path operation* を作りたいとします。

しかし、新しいitemも許可したいです。itemが存在しない場合は、それらを作成して201 "Created"を返します。

これを達成するには、 `JSONResponse` をインポートし、 `status_code` を設定して直接内容を返します。
