Si te comunicas con esa *path operation* enviando dos headers HTTP como:

```
X-Token: foo
X-Token: bar
```

El response sería como:

```JSON
{
    "X-Token values": [
        "bar",
        "foo"
    ]
}
```

## Recapitulación

Declara headers con `Header`, usando el mismo patrón común que `Query`, `Path` y `Cookie`.

Це означатиме, що  **FastAPI**  очікуватиме тіло запиту такого вигляду:

```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"
    }
}
```

Завдяки такій декларації у **FastAPI** Ви отримуєте:

    assertEquals("Foo", new ClassInfo(FILE, "a/b/Bar$Foo.class", classLoader).getSimpleName());
    assertEquals("", new ClassInfo(FILE, "a/b/Bar$1.class", classLoader).getSimpleName());
