おそらくコードの中で直接使用する必要はないでしょう。

しかし、高度なシナリオのために必要な場合には、カスタムヘッダーを追加することができます:

## カスタム例外ハンドラのインストール

カスタム例外ハンドラは<a href="https://www.starlette.dev/exceptions/" class="external-link" target="_blank">Starletteと同じ例外ユーティリティ</a>を使用して追加することができます。

あなた（または使用しているライブラリ）が`raise`するかもしれないカスタム例外`UnicornException`があるとしましょう。

そして、この例外をFastAPIでグローバルに処理したいと思います。
