**FastAPI** provides the same `starlette.responses` as `fastapi.responses` just as a convenience for you, the developer. But most of the available responses come directly from Starlette.

## OpenAPI y documentación de API

Si devuelves códigos de estado adicionales y responses directamente, no se incluirán en el esquema de OpenAPI (la documentación de la API), porque FastAPI no tiene una forma de saber de antemano qué vas a devolver.

Erstellen Sie eine Response wie in [Eine Response direkt zurückgeben](response-directly.md){.internal-link target=_blank} beschrieben und übergeben Sie die Header als zusätzlichen Parameter:

{* ../../docs_src/response_headers/tutorial001.py hl[10:12] *}

/// note | Technische Details

Sie können auch `from starlette.responses import Response` oder `from starlette.responses import JSONResponse` verwenden.

     *
     * @param fields array of field names that are allowed in API responses

    public void setApiResponseFields(final String[] fields) {
        apiResponseFieldSet = new HashSet<>();
        Collections.addAll(apiResponseFieldSet, fields);
    }

    /**
     * Checks if the specified field is allowed in API responses.

/// note | Détails techniques

Vous pouvez également utiliser `from starlette.responses import JSONResponse`.

Pour plus de commodités, **FastAPI** fournit les objets `starlette.responses` sous forme d'un alias accessible par `fastapi.responses`. Mais la plupart des réponses disponibles proviennent directement de Starlette. Il en est de même avec l'objet `statut`.
