## 自動変換 { #automatic-conversion }

`Header`は`Path`や`Query`、`Cookie`が提供する機能に加え、少しだけ追加の機能を持っています。

ほとんどの標準ヘッダーは、「マイナス記号」（`-`）としても知られる「ハイフン」文字で区切られています。

しかし、`user-agent`のような変数はPythonでは無効です。

そのため、デフォルトでは、`Header`はパラメータ名の文字をアンダースコア（`_`）からハイフン（`-`）に変換して、ヘッダーを抽出して文書化します。

また、HTTPヘッダは大文字小文字を区別しないので、Pythonの標準スタイル（別名「スネークケース」）で宣言することができます。
