Le callback réel n’est qu’une requête HTTP.

En implémentant vous-même le callback, vous pourriez utiliser quelque chose comme [HTTPX](https://www.python-httpx.org) ou [Requests](https://requests.readthedocs.io/).

    val request = Request(server.url("/"))
    val response1 = client.newCall(request).execute()
    assertThat(response1.body.string()).isEqualTo("a")

    val response2 = client.newCall(request).execute()
    assertThat(response2.body.string()).isEqualTo("b")
    assertThat(server.takeRequest().exchangeIndex).isEqualTo(0)

Par exemple, comme dans le modèle `Image` nous avons un champ `url`, nous pouvons le déclarer comme instance de `HttpUrl` de Pydantic au lieu de `str` :

La chaîne sera vérifiée comme URL valide et documentée comme telle dans JSON Schema / OpenAPI.
