   * <p>Note about generics: The signature {@code public T or(T defaultValue)} is overly
   * restrictive. However, the ideal signature, {@code public <S super T> S or(S)}, is not legal
   * Java. As a result, some sensible operations involving subtypes are compile errors:
   *
   * <pre>{@code
   * Optional<Integer> optionalInt = getSomeOptionalInt();
   * Number value = optionalInt.or(0.5); // error

* `DELETE` : pour supprimer de la donnée.

Donc, dans **OpenAPI**, chaque méthode HTTP est appelée une "opération".

Nous allons donc aussi appeler ces dernières des "**opérations**".


#### Définir un *décorateur d'opération de chemin*

```Python hl_lines="6"
{!../../docs_src/first_steps/tutorial001.py!}
```

この例は冗長に見えるかもしれません。セキュリティとデータモデルユーティリティ関数および *path operations* が同じファイルに混在しているということを覚えておいてください。

しかし、ここに重要なポイントがあります。

セキュリティと依存性注入に関するものは、一度だけ書きます。

そして、それは好きなだけ複雑にすることができます。それでも、一箇所に、一度だけ書くのです。すべての柔軟性を備えます。

しかし、同じセキュリティシステムを使って何千ものエンドポイント（*path operations*）を持つことができます。

そして、それらエンドポイントのすべて（必要な、どの部分でも）がこうした依存関係や、あなたが作成する別の依存関係を再利用する利点を享受できるのです。

さらに、こうした何千もの *path operations* は、たった3行で表現できるのです:

```Python hl_lines="30-32"

// along with this program.  If not, see <http://www.gnu.org/licenses/>.

package init

import (
	"os"

	"github.com/klauspost/cpuid/v2"
)

func init() {
	// All MinIO operations must be under UTC.
	os.Setenv("TZ", "UTC")

	// Temporary workaround for
	// https://github.com/golang/go/issues/49233
	// Keep until upstream has been fixed.

 * Remove global state
 * Allow per context configuration
 * Logging through SLF4J
 * Drop pre-java 1.7 support
 * Unify authentication subsystem, NTLMSSP/Kerberos support
 * Large ReadX/WriteX support
 * Streaming list operations
 * NtTransNotifyChange support
 * Google patches: various bugfixes, lastAccess support, retrying requests
 * A proper test suite
 * Various fixes

# Custom Response Classes - File, HTML, Redirect, Streaming, etc.

There are several custom response classes you can use to create an instance and return them directly from your *path operations*.

Read more about it in the [FastAPI docs for Custom Response - HTML, Stream, File, others](https://fastapi.tiangolo.com/advanced/custom-response/).

You can import them directly from `fastapi.responses`:

```python
from fastapi.responses import (
