O valor do parâmetro que foi passado à `item_id` será passado para a sua função como o argumento `item_id`.

Então, se você rodar este exemplo e for até <a href="http://127.0.0.1:8000/items/foo" class="external-link" target="_blank">http://127.0.0.1:8000/items/foo</a>, você verá a seguinte resposta:

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