El valor del parámetro de path `item_id` será pasado a tu función como el argumento `item_id`.

Entonces, si corres este ejemplo y vas a <a href="http://127.0.0.1:8000/items/foo" class="external-link" target="_blank">http://127.0.0.1:8000/items/foo</a>, verás una respuesta de:

```JSON
{"item_id":"foo"}
```

## Parámetros de path con tipos

Puedes declarar el tipo de un parámetro de path en la función usando las anotaciones de tipos estándar de Python:

 * token68:
 *
 * ```
 * WWW-Authenticate: Digest foo=bar
 * WWW-Authenticate: Digest foo=
 * ```
 *
 * Similarly, the first line has one challenge and the second line has two challenges:
 *
 * ```
 * WWW-Authenticate: Digest ,foo=bar
 * WWW-Authenticate: Digest ,foo
 * ```
 */
fun Headers.parseChallenges(headerName: String): List<Challenge> {

    return unmodifiableTable(table).columnMap();
