## Zusammenfassung

Abgesehen von all den ausgefallenen Wörtern, die hier verwendet werden, ist das **Dependency Injection**-System recht simpel.

Einfach Funktionen, die genauso aussehen wie *Pfadoperation-Funktionen*.

        println("Deployed ${file.name}")
      }
    } catch (e: IllegalArgumentException) {
      if ("Jar does not have a symbolic name" in e.message!!) {
        println("Skipped non-OSGi dependency: ${file.name}")
        return
      }
      throw e
    }
  }

  companion object {
    val fileSystem = FileSystem.SYSTEM

## Dependencias

Vemos que vamos a necesitar algunas dependencias usadas en varios lugares de la aplicación.

Así que las ponemos en su propio módulo `dependencies` (`app/dependencies.py`).

Ahora utilizaremos una dependencia simple para leer un encabezado `X-Token` personalizado:

//// tab | Python 3.9+

```Python hl_lines="3  6-8" title="app/dependencies.py"
{!> ../../docs_src/bigger_applications/app_an_py39/dependencies.py!}
```
