Vemos que precisaremos de algumas dependências usadas em vários lugares da aplicação.

Então, as colocamos em seu próprio módulo de `dependencies` (`app/dependencies.py`).

Agora usaremos uma dependência simples para ler um cabeçalho `X-Token` personalizado:

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