## Details zum `Request`-Objekt

Da **FastAPI** unter der Haube eigentlich **Starlette** ist, mit einer Ebene von mehreren Tools darüber, können Sie Starlette's <a href="https://www.starlette.io/requests/" class="external-link" target="_blank">`Request`</a>-Objekt direkt verwenden, wenn Sie es benötigen.

            return null;
        }
        final String target = getDetectText(text);
        final LanguageResult result = detector.detect(target);
        if (logger.isDebugEnabled()) {
            logger.debug("detected lang:{}({}) from {}", result, result.getRawScore(), target);
        }
        return getSupportedLanguage(result.getLanguage());
    }

# Corpo - Atualizações

## Atualização de dados existentes com `PUT`

Para atualizar um item, você pode usar a operação <a href="https://developer.mozilla.org/en-US/docs/Web/HTTP/Methods/PUT" class="external-link" target="_blank">HTTP `PUT`</a>.

Você pode usar `jsonable_encoder` para converter os dados de entrada em dados que podem ser armazenados como JSON (por exemplo, com um banco de dados NoSQL). Por exemplo, convertendo `datetime` em `str`.

上で読んだように、**FastAPI** のデフォルトのレスポンスとして利用されます。

### `ORJSONResponse`

上で読んだように、<a href="https://github.com/ijl/orjson" class="external-link" target="_blank">`orjson`</a>を使った、高速な代替のJSONレスポンスです。

### `UJSONResponse`

<a href="https://github.com/ultrajson/ultrajson" class="external-link" target="_blank">`ujson`</a>を使った、代替のJSONレスポンスです。

/// warning | 注意

`ujson` は、いくつかのエッジケースの取り扱いについて、Pythonにビルトインされた実装よりも作りこまれていません。
