Näher betrachtet, werden *Pfadoperation-Funktionen* deklariert, um verwendet zu werden, wann immer ein *Pfad* und eine *Operation* übereinstimmen, und dann kümmert sich **FastAPI** darum, die Funktion mit den richtigen Parametern aufzurufen, die Daten aus dem Request extrahierend.

Natürlich können Sie auch, wann immer Sie das brauchen, weitere Query-Parameter hinzufügen, zusätzlich zu den Body-Parametern.
