/// tip | Tipp

Der eigentliche Callback ist nur ein HTTP-Request.

Wenn Sie den Callback selbst implementieren, können Sie beispielsweise [HTTPX](https://www.python-httpx.org) oder [Requests](https://requests.readthedocs.io/) verwenden.

///

## Schreiben des Codes, der den Callback dokumentiert { #write-the-callback-documentation-code }

**FastAPI** will **extract** the data for **each field** from the **form data** in the request and give you the Pydantic model you defined.

## Check the Docs { #check-the-docs }

You can verify it in the docs UI at `/docs`:

<div class="screenshot">
<img src="/img/tutorial/request-form-models/image01.png">
</div>

## Forbid Extra Form Fields { #forbid-extra-form-fields }

**FastAPI**는 요청에서 받은 **폼 데이터**에서 **각 필드**에 대한 데이터를 **추출**하고 정의한 Pydantic 모델을 줍니다.

## 문서 확인하기 { #check-the-docs }

문서 UI `/docs`에서 확인할 수 있습니다:

<div class="screenshot">
<img src="/img/tutorial/request-form-models/image01.png">
</div>

## 추가 폼 필드 금지하기 { #forbid-extra-form-fields }

일부 특별한 사용 사례(아마도 흔하지는 않겠지만)에서는 Pydantic 모델에서 선언된 폼 필드로만 **제한**하길 원할 수도 있습니다. 그리고 **추가** 필드를 **금지**할 수도 있습니다.
