У цьому випадку є 3 параметри query:

* `needy`, обов’язковий `str`.
* `skip`, `int` зі значенням за замовчуванням `0`.
* `limit`, необов’язковий `int`.

/// tip | Порада

Ви також можете використовувати `Enum` так само, як і з [Параметри шляху](path-params.md#predefined-values).

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#predefined-values)中那样使用 `Enum`。
