Fonksiyonunuzdaki parametre değerleri aşağıdaki gibi olacaktır:

* `skip=20`: çünkü bağlantıda böyle tanımlandı.
* `limit=10`: çünkü varsayılan değer buydu.

## İsteğe Bağlı Parametreler

Aynı şekilde, varsayılan değerlerini `None` olarak atayarak isteğe bağlı parametreler tanımlayabilirsiniz:

OpenAPIスキーマを完全に無効にする場合は、`openapi_url=None` を設定できます。これにより、それを使用するドキュメントUIも無効になります。

## ドキュメントのURL

以下の2つのドキュメントUIを構築できます:

* **Swagger UI**: `/docs` で提供されます。
     * URL はパラメータ `docs_url` で設定できます。
     * `docs_url=None` を設定することで無効にできます。
* ReDoc: `/redoc` で提供されます。
     * URL はパラメータ `redoc_url` で設定できます。
     * `redoc_url=None` を設定することで無効にできます。
