# カスタム Request と APIRoute クラス { #custom-request-and-apiroute-class }

場合によっては、`Request` や `APIRoute` クラスで使われるロジックを上書きしたいことがあります。

特に、ミドルウェアでのロジックの代替として有効な場合があります。

たとえば、アプリケーションで処理される前にリクエストボディを読み取ったり操作したりしたい場合です。

/// danger | 警告

これは「上級」機能です。

FastAPI を始めたばかりの場合は、このセクションは読み飛ばしてもよいでしょう。

///

## 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)）。
