## Пример использования { #use-case }

Например, представьте, что вы хотите по умолчанию возвращать HTTP статус-код «OK» `200`.

Но если данные не существовали, вы хотите создать их и вернуть HTTP статус-код «CREATED» `201`.

При этом вы всё ещё хотите иметь возможность фильтровать и преобразовывать возвращаемые данные с помощью `response_model`.

Для таких случаев вы можете использовать параметр `Response`.

Stellen Sie sich zum Beispiel vor, Sie möchten standardmäßig den HTTP-Statuscode „OK“ `200` zurückgeben.

Wenn die Daten jedoch nicht vorhanden sind, möchten Sie diese erstellen und den HTTP-Statuscode „CREATED“ `201` zurückgeben.

Sie möchten aber dennoch in der Lage sein, die von Ihnen zurückgegebenen Daten mit einem `response_model` zu filtern und zu konvertieren.

In diesen Fällen können Sie einen `Response`-Parameter verwenden.

But you also want it to accept new items. And when the items didn't exist before, it creates them, and returns an HTTP status code of 201 "Created".

To achieve that, import `JSONResponse`, and return your content there directly, setting the `status_code` that you want:

{* ../../docs_src/additional_status_codes/tutorial001_an_py310.py hl[4,25] *}

## Use case { #use-case }

For example, imagine that you want to return an HTTP status code of "OK" `200` by default.

But if the data didn't exist, you want to create it, and return an HTTP status code of "CREATED" `201`.

But you still want to be able to filter and convert the data you return with a `response_model`.

For those cases, you can use a `Response` parameter.
