## 总结

你能够以与 [查询参数和字符串校验](query-params-str-validations.md){.internal-link target=_blank} 相同的方式使用 `Query`、`Path`（以及其他你还没见过的类）声明元数据和字符串校验。

而且你还可以声明数值校验：

* `gt`：大于（`g`reater `t`han）
* `ge`：大于等于（`g`reater than or `e`qual）
* `lt`：小于（`l`ess `t`han）
* `le`：小于等于（`l`ess than or `e`qual）

!!! info
    `Query`、`Path` 以及你后面会看到的其他类继承自一个共同的 `Param` 类（不需要直接使用它）。

    而且它们都共享相同的所有你已看到并用于添加额外校验和元数据的参数。

Und Sie können auch Validierungen für Zahlen deklarieren:

* `gt`: `g`reater `t`han – größer als
* `ge`: `g`reater than or `e`qual – größer oder gleich
* `lt`: `l`ess `t`han – kleiner als
* `le`: `l`ess than or `e`qual – kleiner oder gleich
