## ユースケース { #use-cases }

ユースケースの例:

* JSON ではないリクエストボディを JSON に変換する（例: [`msgpack`](https://msgpack.org/index.html)）。
* gzip 圧縮されたリクエストボディの解凍。
* すべてのリクエストボディの自動ロギング。

## カスタムリクエストボディのエンコーディングの処理 { #handling-custom-request-body-encodings }

gzip のリクエストを解凍するために、カスタムの `Request` サブクラスを使う方法を見ていきます。

そして、そのカスタムリクエストクラスを使うための `APIRoute` サブクラスを用意します。
