#### OkHttpClient final methods

`OkHttpClient` has 26 accessors like `interceptors()` and `writeTimeoutMillis()` that were non-final
in OkHttp 3.x and are final in 4.x. These were made non-final for use with mocking frameworks like
[Mockito][mockito]. We believe subtyping `OkHttpClient` is the wrong way to test with OkHttp. If

Il existe également un **Guide d'utilisation avancé** que vous pouvez lire plus tard après ce **Tutoriel - Guide d'utilisation**.

Le **Guide d'utilisation avancé**, qui s'appuie sur cette base, utilise les mêmes concepts et vous apprend quelques fonctionnalités supplémentaires.

Mais vous devez d'abord lire le **Tutoriel - Guide d'utilisation** (ce que vous êtes en train de lire en ce moment).

Nous les mettons donc dans leur propre module `dependencies` (`app/dependencies.py`).

Nous allons maintenant utiliser une dépendance simple pour lire un en-tête personnalisé `X-Token` :

## FastAPI Responses

There were a couple of custom FastAPI response classes that were intended to optimize JSON performance.

However, they are now deprecated as you will now get better performance by using a [Response Model - Return Type](https://fastapi.tiangolo.com/tutorial/response-model/).

Wenn Sie möchten, dass der Client Informationen im Request übergibt und Sie nicht wissen, wie das geht, können Sie suchen (googeln), wie es mit `httpx` gemacht wird, oder sogar, wie es mit `requests` gemacht wird, da das Design von HTTPX auf dem Design von Requests basiert.

Dann machen Sie in Ihren Tests einfach das gleiche.

Z. B.:

     * @param originatingArtifact the artifact that was being resolved
     * @param missingArtifacts    artifacts that could not be resolved
