In diesem Fall gibt es drei Query-Parameter:

* `needy`, ein erforderlicher `str`.
* `skip`, ein `int` mit einem Defaultwert `0`.
* `limit`, ein optionales `int`.

/// tip | "Tipp"

Sie können auch `Enum`s verwenden, auf die gleiche Weise wie mit [Pfad-Parametern](path-params.md#vordefinierte-parameterwerte){.internal-link target=_blank}.
