El valor del parámetro de path `item_id` se pasará a tu función como el argumento `item_id`.

Así que, si ejecutas 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 un response de:

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

## Parámetros de path con tipos

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

#,$,%,^,&,*,?,_,~])/)&&a.match(/([a-zA-Z])/)&&(b+=15),(a.match(/^\w+$/)||a.match(/^\d+$/))&&(b-=10),b<0&&(b=0),b>100&&(b=100),b<20?0:b<40?1:b<=60?2:3},strengthDisplay:function(b,c){var d={fontSize:"12pt",padding:"4px",bad:"Very bad",weak:"Weak",good:"Good",strong:"Strong"};c&&a.extend(d,c),b.bind("keyup",function(){var b=a(this).val(),c="undefined"==typeof d.parent?a(this).parent():a(d.parent),e=c.find(".strength-meter"),f=a.formUtils.validators.validate_strength.calculatePasswordStrength(b),g={...

</body>

이는 **FastAPI**가 다음과 유사한 본문을 기대한다는 것을 의미합니다:

```JSON
{
    "name": "Foo",
    "description": "The pretender",
    "price": 42.0,
    "tax": 3.2,
    "tags": ["rock", "metal", "bar"],
    "image": {
        "url": "http://example.com/baz.jpg",
        "name": "The Foo live"
    }
}
```

다시 한번, **FastAPI**를 사용하여 해당 선언을 함으로써 얻는 것은:

* 중첩 모델도 편집기 지원(자동완성 등)
* 데이터 변환

    Iterable<String> iterable = singletonList("foo");
    assertEquals("foo", getOnlyElement(iterable));
  }

  public void testGetOnlyElement_noDefault_empty() {
    Iterable<String> iterable = emptyList();
    assertThrows(NoSuchElementException.class, () -> getOnlyElement(iterable));
  }

  public void testGetOnlyElement_noDefault_multiple() {
    Iterable<String> iterable = asList("foo", "bar");

                </div>
            </la:form>
        </section>
    </div>
    <jsp:include page="/WEB-INF/view/common/admin/footer.jsp"></jsp:include>
</div>
<jsp:include page="/WEB-INF/view/common/admin/foot.jsp"></jsp:include>
</body>

   documentation may negatively impact others.

 * **Be respectful**: We expect people to work together to resolve conflict, assume good intentions,
   and act with empathy. Do not turn disagreements into personal attacks.

 * **Be collaborative**: Collaboration reduces redundancy and improves the quality of our work. We

Используя эти идеи, JWT можно применять для гораздо более сложных сценариев.

В отдельных случаях несколько сущностей могут иметь один и тот же идентификатор, скажем, `foo` (пользователь `foo`, автомобиль `foo` и запись в блоге `foo`).
