# Beispiel-Request-Daten deklarieren { #declare-request-example-data }

Sie können Beispiele für die Daten deklarieren, die Ihre App empfangen kann.

Hier sind mehrere Möglichkeiten, das zu tun.

## Zusätzliche JSON-Schemadaten in Pydantic-Modellen { #extra-json-schema-data-in-pydantic-models }

Sie können `examples` („Beispiele“) für ein Pydantic-Modell deklarieren, welche dem generierten JSON-Schema hinzugefügt werden.

///

## Über „Formularfelder“ { #about-form-fields }

HTML-Formulare (`<form></form>`) senden die Daten in einer „speziellen“ Kodierung zum Server, die sich von JSON unterscheidet.

**FastAPI** stellt sicher, dass diese Daten korrekt ausgelesen werden, statt JSON zu erwarten.
