#### Die `openapi.json` testen { #check-the-openapi-json }

Falls Sie wissen möchten, wie das rohe OpenAPI-Schema aussieht: FastAPI generiert automatisch ein JSON (Schema) mit den Beschreibungen Ihrer gesamten API.

Esto es muy útil cuando necesitas:

* Tener lógica compartida (la misma lógica de código una y otra vez).
* Compartir conexiones a bases de datos.
* Imponer seguridad, autenticación, requisitos de roles, etc.
* Y muchas otras cosas...

Todo esto, mientras minimizas la repetición de código.

## Primeros Pasos { #first-steps }

Veamos un ejemplo muy simple. Será tan simple que no es muy útil, por ahora.

Und Sie können Abhängigkeiten mit `async def` innerhalb normaler `def`-*Pfadoperation-Funktionen* oder `def`-Abhängigkeiten innerhalb von `async def`-*Pfadoperation-Funktionen*, usw. deklarieren.

Es spielt keine Rolle. **FastAPI** weiß, was zu tun ist.
