# Utiliser des classes comme dépendances { #classes-as-dependencies }

Avant d'aller plus loin dans le système d'**Injection de dépendances**, mettons à niveau l'exemple précédent.

## Un `dict` de l'exemple précédent { #a-dict-from-the-previous-example }

Dans l'exemple précédent, nous renvoyions un `dict` depuis notre dépendance (« dependable ») :

{* ../../docs_src/dependencies/tutorial001_an_py310.py hl[9] *}

Примеры инструментов, которые могут с этим справиться:

* Docker
* Kubernetes
* Docker Compose
* Docker в режиме Swarm (Swarm Mode)
* Systemd
* Supervisor
* Обработка внутри облачного провайдера как часть его услуг
* Прочие...

Более конкретные примеры будут в следующих главах.

## Перезапуски { #restarts }

### Приклади інструментів для запуску під час старту { #example-tools-to-run-at-startup }

Приклади інструментів, які можуть це робити:

- Docker
- Kubernetes
- Docker Compose
- Docker у режимі Swarm
- Systemd
- Supervisor
- Обробляється внутрішньо хмарним провайдером як частина їхніх сервісів
- Інші...

У наступних розділах я наведу більш конкретні приклади.

## Перезапуски { #restarts }

 *   <li>Avoid logging instances of this class as it may expose credentials</li>
 *   <li>Consider using external secret management systems for credential storage in production</li>
 * </ul>

Uygulamayı servis etmeye devam ederken tüm bu yenileme sürecini yönetebilmek, TLS sertifikalarını doğrudan uygulama server’ıyla (örn. Uvicorn) kullanmak yerine, TLS Termination Proxy ile HTTPS’i yönetecek **ayrı bir sistem** istemenizin başlıca nedenlerinden biridir.

## Proxy Forwarded Headers { #proxy-forwarded-headers }

 * It manages the crawling lifecycle, including initialization, execution coordination,
 * monitoring, and cleanup operations.
 *
 * <p>The crawler can operate in different modes based on command-line options:
 * <ul>
 * <li>Web crawling - crawls web sites and web content</li>
 * <li>File system crawling - crawls file systems and documents</li>

 * S3-compatible storage client implementation using AWS SDK v2.
 * Supports Amazon S3, MinIO, and other S3-compatible storage systems.

public class S3StorageClient implements StorageClient {

    private static final Logger logger = LogManager.getLogger(S3StorageClient.class);

    private final S3Client s3Client;

Here's a little bit of that history.

## Alternatives { #alternatives }

I have been creating APIs with complex requirements for several years (Machine Learning, distributed systems, asynchronous jobs, NoSQL databases, etc), leading several teams of developers.

As part of that, I needed to investigate, test and use many alternatives.
