Вы можете использовать класс `Enum` также, как ранее применяли его с [Path-параметрами](path-params.md#predefined-values){.internal-link target=_blank}.

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

/// tip | 提示

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