```

## Tip İçeren Yol Parametreleri

Значення параметра шляху `item_id` передається у функцію як аргумент `item_id`.

Якщо запустити цей приклад та перейти за посиланням <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 отримаємо таку відповідь:

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

## Path параметри з типами

Ви можете визначити тип параметра шляху у функції, використовуючи стандартні анотації типів Python:

app = FastAPI()


class Item(BaseModel):
    name: str
    description: str | None = None
    price: float
    tax: float = 10.5
    tags: list[str] = []


items = {
    "foo": {"name": "Foo", "price": 50.2},
    "bar": {"name": "Bar", "description": "The bartenders", "price": 62, "tax": 20.2},
    "baz": {"name": "Baz", "description": None, "price": 50.2, "tax": 10.5, "tags": []},
}

public class SingleValueIteratorTest {

    /**
     *
     */
    @Test
    public void test() {
        final SingleValueIterator<String> it = new SingleValueIterator<String>("Foo");
        assertThat(it.hasNext(), is(true));
        assertThat(it.next(), is("Foo"));
        assertThat(it.hasNext(), is(not(true)));
    }
