本例中有 3 个查询参数：

* `needy`，必选的 `str` 类型参数
* `skip`，默认值为 `0` 的 `int` 类型参数
* `limit`，可选的 `int` 类型参数

还可以像在[路径参数](path-params.md#_8){.internal-link target=_blank} 中那样使用 `Enum`。

Das alles mag gekünstelt wirken. Und es ist möglicherweise noch nicht ganz klar, welchen Nutzen das hat.

Diese Beispiele sind bewusst einfach gehalten, zeigen aber, wie alles funktioniert.

In den Kapiteln zum Thema Sicherheit gibt es Hilfsfunktionen, die auf die gleiche Weise implementiert werden.

Independent TechEmpower benchmarks show **FastAPI** applications running under Uvicorn as <a href="https://www.techempower.com/benchmarks/#section=test&runid=7464e520-0dc2-473d-bd34-dbdfd7e85911&hw=ph&test=query&l=zijzen-7" class="external-link" target="_blank">one of the fastest Python frameworks available</a>, only below Starlette and Uvicorn themselves (used internally by FastAPI).

But when checking benchmarks and comparisons you should keep the following in mind.
