```

もし、その*path operation*で通信する場合は、次のように２つのHTTPヘッダーを送信します:

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

このレスポンスは以下のようになります:

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

## まとめ

ヘッダーは`Header`で宣言し、`Query`や`Path`、`Cookie`と同じパターンを使用する。

The command will generate the `scrape_configs` section of the prometheus.yml as follows:
