{* ../../docs_src/response_model/tutorial002.py hl[9,11] *}

そして、このモデルを使用して入力を宣言し、同じモデルを使って出力を宣言しています:

{* ../../docs_src/response_model/tutorial002.py hl[17,18] *}

これで、ブラウザがパスワードを使ってユーザーを作成する際に、APIがレスポンスで同じパスワードを返すようになりました。

この場合、ユーザー自身がパスワードを送信しているので問題ないかもしれません。

しかし、同じモデルを別の*path operation*に使用すると、すべてのクライアントにユーザーのパスワードを送信してしまうことになります。

/// danger | 危険

ユーザーの平文のパスワードを保存したり、レスポンスで送信したりすることは絶対にしないでください。
