### Возвращаемый ответ

Если клиент запросит `http://example.com/items/foo` (`item_id` `"foo"`), то он получит статус-код 200 и ответ в формате JSON:

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

```

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:

  public void testLenientFormat() {
    assertEquals("%s", Strings.lenientFormat("%s"));
    assertEquals("5", Strings.lenientFormat("%s", 5));
    assertEquals("foo [5]", Strings.lenientFormat("foo", 5));
    assertEquals("foo [5, 6, 7]", Strings.lenientFormat("foo", 5, 6, 7));
    assertEquals("%s 1 2", Strings.lenientFormat("%s %s %s", "%s", 1, 2));
    assertEquals(" [5, 6]", Strings.lenientFormat("", 5, 6));
