////

Если вы взаимодействуете с этой *операцией пути*, отправляя два HTTP-заголовка, таких как:

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

Ответ был бы таким:

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

## Резюме

Объявляйте заголовки с помощью `Header`, используя тот же общий шаблон, как при `Query`, `Path` и `Cookie`.

```

////

Wenn Sie mit einer *Pfadoperation* kommunizieren, die zwei HTTP-Header sendet, wie:

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

Dann wäre die Response:

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

## Zusammenfassung

Deklarieren Sie Header mittels `Header`, auf die gleiche Weise wie bei `Query`, `Path` und `Cookie`.
