Es gibt jedoch Situationen, in denen Sie möglicherweise direkt auf das `Request`-Objekt zugreifen müssen.

## Details zum `Request`-Objekt { #details-about-the-request-object }

Da **FastAPI** unter der Haube eigentlich **Starlette** ist, mit einer Ebene von mehreren Tools darüber, können Sie Starlettes [`Request`](https://www.starlette.dev/requests/)-Objekt direkt verwenden, wenn Sie es benötigen.
