## まとめ

`Query`と`Path`（そしてまだ見たことない他のもの）では、[クエリパラメータと文字列の検証](query-params-str-validations.md){.internal-link target=_blank}と同じようにメタデータと文字列の検証を宣言することができます。

また、数値のバリデーションを宣言することもできます:

* `gt`: より大きい（`g`reater `t`han）
* `ge`: 以上（`g`reater than or `e`qual）
* `lt`: より小さい（`l`ess `t`han）

Aber der Client/Benutzer sieht ihn nicht. Stattdessen erhält der Client einen <abbr title="Interner Server-Fehler">„Internal Server Error“</abbr> mit einem HTTP-Statuscode `500`.

Die Verwendung einer relativen URL ist wichtig, um sicherzustellen, dass Ihre Anwendung auch in einem fortgeschrittenen Anwendungsfall, wie [hinter einem Proxy](../../advanced/behind-a-proxy.md){.internal-link target=_blank}, weiterhin funktioniert.
