Wenn Sie beispielsweise einen Header-Parameter `save_data` im Code haben, wird der erwartete HTTP-Header `save-data` sein, und er wird auch so in der Dokumentation angezeigt.

Falls Sie aus irgendeinem Grund diese automatische Umwandlung deaktivieren müssen, können Sie dies auch für Pydantic-Modelle für Header-Parameter tun.

If you look at it, *path operation functions* are declared to be used whenever a *path* and *operation* matches, and then **FastAPI** takes care of calling the function with the correct parameters, extracting the data from the request.

Actually, all (or most) of the web frameworks work in this same way.

You never call those functions directly. They are called by your framework (in this case, **FastAPI**).

Esto te dará soporte del editor dentro de tu función, con chequeo de errores, autocompletado, etc.
