Das ist sehr nützlich, wenn Sie:

* Eine gemeinsame Logik haben (die gleiche Code-Logik immer und immer wieder).
* Datenbankverbindungen teilen.
* Sicherheit, Authentifizierung, Rollenanforderungen, usw. durchsetzen.
* Und viele andere Dinge ...

All dies, während Sie Codeverdoppelung minimieren.

## Erste Schritte

* <a href="https://github.com/swagger-api/swagger-ui" class="external-link" target="_blank"><strong>Swagger UI</strong></a>, bietet interaktive Erkundung, testen und rufen Sie ihre API direkt im Webbrowser auf.

You can declare path parameters and request body at the same time.

**FastAPI** will recognize that the function parameters that match path parameters should be **taken from the path**, and that function parameters that are declared to be Pydantic models should be **taken from the request body**.
