Also fügen wir sie in ihr eigenes `dependencies`-Modul (`app/dependencies.py`) ein.

Wir werden nun eine einfache Abhängigkeit verwenden, um einen benutzerdefinierten `X-Token`-Header zu lesen:

{* ../../docs_src/bigger_applications/app_an_py39/dependencies.py hl[3,6:8] title["app/dependencies.py"] *}

/// tip | Tipp

Мы поместим их в отдельный модуль `dependencies` (`app/dependencies.py`).

Теперь мы воспользуемся простой зависимостью, чтобы прочитать кастомизированный `X-Token` из заголовка:

{* ../../docs_src/bigger_applications/app_an_py39/dependencies.py hl[3,6:8] title["app/dependencies.py"] *}

/// tip | Подсказка

Для простоты мы воспользовались неким воображаемым заголовоком.
