Template içinde `url_for()` da kullanabilirsiniz; argüman olarak, *path operation function*'ınızın kullandığı argümanların aynısını alır.

Dolayısıyla şu bölüm:

{% raw %}

```jinja
<a href="{{ url_for('read_item', id=id) }}">
```

{% endraw %}

...*path operation function* olan `read_item(id=id)` tarafından handle edilecek URL'nin aynısına bir link üretir.

También puedes usar `url_for()` dentro de la plantilla, toma como argumentos los mismos que usaría tu *path operation function*.

Entonces, la sección con:

{% raw %}

```jinja
<a href="{{ url_for('read_item', id=id) }}">
```

{% endraw %}

...generará un enlace hacia la misma URL que manejaría la *path operation function* `read_item(id=id)`.

Por ejemplo, con un ID de `42`, esto se renderizaría como:

```html

* feature: funcionalidad
* sponsor: sponsor
* host (in a podcast): host
* request (as in HTTP request): request
* response (as in HTTP response): response
* path operation function: path operation function (do not translate to "función de operación de ruta")
* path operation: path operation (do not translate to "operación de ruta")
* path (as in URL path): path (do not translate to "ruta")
* query (as in URL query): query (do not translate to "consulta")

/// tip | 豆知識

`swagger_ui_redirect` 用の *path operation* は、OAuth2 を使用する場合の補助です。

API を OAuth2 プロバイダと統合すると、認証を実行して取得したクレデンシャルを持った状態で API ドキュメントに戻れます。そして実際の OAuth2 認証を用いてドキュメント上から API と対話できます。

Swagger UI がこの処理を裏側で行いますが、そのためにこの「redirect」の補助が必要です。

### テスト用の *path operation* を作成 { #create-a-path-operation-to-test-it }

すべてが動作するかをテストできるように、*path operation* を作成します:

import java.io.Reader;
import java.util.Iterator;
import org.jspecify.annotations.Nullable;

/**
 * A {@link Reader} that concatenates multiple readers.
 *
 * @author Bin Zhu
 * @since 1.0
 */
@J2ktIncompatible
@GwtIncompatible
final class MultiReader extends Reader {
  private final Iterator<? extends CharSource> it;
  private @Nullable Reader current;

max_sleep      (duration)  maximum sleep duration between objects to slow down heal operation. eg. 2s
max_io         (int)       maximum IO requests allowed between objects to slow down heal operation. eg. 3
drive_workers  (int)       the number of workers per drive to heal a new disk replacement.
```

Dans ce cas, elles seront appliquées à tous les *chemins d'accès* de l'application :
