次の章では、FastAPIアプリケーションをデプロイするための**具体的なレシピ**を紹介します。

しかし、今はこれらの重要な**コンセプトに基づくアイデア**を確認しましょう。これらのコンセプトは、他のどのタイプのWeb APIにも当てはまります。💡

## セキュリティ - HTTPS

<!-- NOTE: https.md written in Japanese does not exist, so it redirects to English one  -->
[前チャプターのHTTPSについて](https.md){.internal-link target=_blank}では、HTTPSがどのようにAPIを暗号化するのかについて学びました。

通常、アプリケーションサーバにとって**外部の**コンポーネントである**TLS Termination Proxy**によって提供されることが一般的です。このプロキシは通信の暗号化を担当します。

        valueMap.put("action", action.replace('\t', '_').toUpperCase(Locale.ENGLISH));
        valueMap.put("user", user.map(FessUserBean::getUserId).orElse("-"));
        final Comparator<Map.Entry<String, String>> c = Comparator.comparing(Map.Entry::getKey);

 * - JUnit 5 is used; Mockito is not required here.
