declarar um modelo de resposta, o FastAPI usará o `jsonable_encoder` explicado em [Codificador Compatível com JSON](../tutorial/encoder.md) e o colocará em uma `JSONResponse`.

Se você declarar uma `response_class` com um media type JSON (`application/json`), como no caso de `JSONResponse`, os dados que você retorna serão automaticamente convertidos (e filtrados) com qualquer `response_model` do Pydantic que você declarou no *decorador de operação de rota*. Mas os dados não serão serializados...

constraints.UriType.message = {item} a un URI non reconnu.
constraints.CronExpression.message = {item} n'est pas une expression CRON valide.

déclarez pas de modèle de réponse, FastAPI utilisera le `jsonable_encoder` expliqué dans [Encodeur compatible JSON](../tutorial/encoder.md) et le placera dans une `JSONResponse`.

Si vous déclarez une `response_class` avec un media type JSON (`application/json`), comme c'est le cas avec `JSONResponse`, les données que vous renvoyez seront automatiquement converties (et filtrées) avec tout `response_model` Pydantic que vous avez déclaré dans le décorateur de *chemin d'accès*. Mais les données ne seront...

container.singleton("tikaExtractor", TikaExtractor.class);
container.singleton("extractorFactory", ExtractorFactory.class, factory -> {
    factory.addExtractor("text/html", container.getComponent("tikaExtractor"));
    factory.addExtractor("application/pdf", container.getComponent("tikaExtractor"));
});

Crawler crawler = container.getComponent("crawler");
crawler.addUrl("https://example.com");
crawler.crawlerContext.setMaxAccessCount(500);

Instead it takes the JSON bytes generated with Pydantic using the response model (or return type) and returns a `Response` with the right media type for JSON directly (`application/json`).

## Notes { #notes }

When you return a `Response` directly its data is not validated, converted (serialized), or documented automatically.
