これにより、`GzipRequest` は必要に応じてデータを解凍してから *path operations* に渡します。

それ以降の処理ロジックはすべて同じです。

ただし、`GzipRequest.body` を変更しているため、必要に応じて **FastAPI** によって読み込まれる際にリクエストボディが自動的に解凍されます。

## 例外ハンドラでのリクエストボディへのアクセス { #accessing-the-request-body-in-an-exception-handler }

/// tip | 豆知識

同じ問題を解決するには、`RequestValidationError` 用のカスタムハンドラで `body` を使う方がずっと簡単でしょう（[エラー処理](../tutorial/handling-errors.md#use-the-requestvalidationerror-body)）。

ただし、この例も有効で、内部コンポーネントとどのようにやり取りするかを示しています。
