Mesmo que o sistema hierárquico de injeção de dependência seja simples de definir e utilizar, ele ainda é bastante poderoso.

Você pode definir dependências que por sua vez definem suas próprias dependências.

No fim, uma árvore hierárquica de dependências é criadas, e o sistema de **Injeção de Dependência** toma conta de resolver todas essas dependências (e as sub-dependências delas) para você, e provê (injeta) os resultados em cada passo.

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:

/// tip | Tipp

  # Find all one-step dependencies of those tests which are from //tensorflow
  # (since external deps will come from Python-level pip dependencies),
  # excluding dependencies and files that are known to be unneccessary.
  # This creates a list of targets under //tensorflow that are required for
  # TensorFlow python tests.

Параметры `prefix`, `tags`, `responses` и `dependencies` относятся к функционалу **FastAPI**, помогающему избежать дублирования кода.

### Импорт зависимостей { #import-the-dependencies }

Наш код находится в модуле `app.routers.items` (файл `app/routers/items.py`).

И нам нужно вызвать функцию зависимости из модуля `app.dependencies` (файл `app/dependencies.py`).
