Затем, получив такой URL:

```
http://localhost:8000/items/?q=foo&q=bar
```

вы бы получили несколько значений (`foo` и `bar`), которые относятся к параметру `q`, в виде Python `list` внутри вашей *функции обработки пути*, в *параметре функции* `q`.

Таким образом, ответ на этот URL будет:

```JSON
{
  "q": [
    "foo",
    "bar"
  ]
}
```

            @Override
            public void startElement(final String uri, final String localName, final String qName, final Attributes attributes)
                    throws SAXException {
                if ("bar".equals(qName)) {
                    included = true;
                }
            }

            @Override

                                        "description": "FastAPI can convert price `strings` to actual `numbers` automatically",
                                        "value": {"name": "Bar", "price": "35.4"},
                                    },
                                    "invalid": {
                                        "summary": "Invalid data is rejected with an error",

    public interface Foo<T1, T2> {

        /**
         * @param foo
         * @return T2
         */
        T2 foo(T1 foo);
    }

    /**
     *
     */
    public interface Bar extends Foo<Integer, Long> {
    }

    /**
     * @param <T1>
     * @param <T2>
     *
     */
    public interface Baz<T1, T2> {

        /**
         * @return T1
         */

```JSON
{
  "item": "The Foo Wrestlers"
}
```

Но если клиент запросит `http://example.com/items/bar` (несуществующий `item_id` `"bar"`), то он получит статус-код 404 (ошибка "не найдено") и JSON-ответ в виде:

```JSON
{
  "detail": "Item not found"
}
```

/// tip | "Подсказка"

```

Isso significa que o **FastAPI** vai esperar um corpo similar à:

```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"
    }
}
```

Novamente, apenas fazendo essa declaração, com o **FastAPI**, você ganha:
