Ein `Request` hat ein `request.scope`-Attribut, welches einfach ein Python-<abbr title="Dictionary – Zuordnungstabelle: In anderen Sprachen auch Hash, Map, Objekt, Assoziatives Array genannt">`dict`</abbr> ist, welches die mit dem Request verbundenen Metadaten enthält.

Ein `Request` hat auch ein `request.receive`, welches eine Funktion ist, die den Body des Requests <abbr title="Englisch „receive“">empfängt</abbr>.

Zuerst einmal, Sie können `Path`-, `Query`- und Requestbody-Parameter-Deklarationen frei mischen und **FastAPI** wird wissen, was zu tun ist.

Und Sie können auch Body-Parameter als optional kennzeichnen, indem Sie den Defaultwert auf `None` setzen:

Sie können das Ausgabemodell auch in der Dokumentation überprüfen. **Sowohl** `name` **als auch** `description` sind mit einem **roten Sternchen** als **erforderlich** markiert:

- Tooling API client. This a library that is embedded into applications, such as IDEs or CI agents, that allows them to act as a Gradle client.
- Worker processes. Long-running daemon processes that the Gradle daemon starts to run specific kinds of work, such as compilation or test execution.

The diagram below shows the relationships between the different processes:
