Значение параметра пути `item_id` будет передано в функцию в качестве аргумента `item_id`.

Если запустите этот пример и перейдёте по адресу: <a href="http://127.0.0.1:8000/items/foo" class="external-link" target="_blank">http://127.0.0.1:8000/items/foo</a>, то увидите ответ:

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

## Параметры пути с типами

Вы можете объявить тип параметра пути в функции, используя стандартные аннотации типов Python.

```Python hl_lines="7"

Wenn Sie dieses Beispiel ausführen und auf <a href="http://127.0.0.1:8000/items/foo" class="external-link" target="_blank">http://127.0.0.1:8000/items/foo</a> gehen, sehen Sie als Response:

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

## Pfad-Parameter mit Typen

    Predicate<String> equalsFoo = Predicates.equalTo("Foo");
    Predicate<String> equalsBar = Predicates.equalTo("Bar");
    Predicate<String> trimEqualsFoo = Predicates.compose(equalsFoo, trim);
    Function<String, String> identity = Functions.identity();

    assertTrue(trimEqualsFoo.apply("Foo"));
    assertTrue(trimEqualsFoo.apply("   Foo   "));
    assertFalse(trimEqualsFoo.apply("Foo-b-que"));
