**FastAPI** 将从请求中的**表单数据**中**提取**出**每个字段**的数据，并提供您定义的 Pydantic 模型。

## 检查文档

您可以在文档 UI 中验证它，地址为 `/docs` ：

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

## 禁止额外的表单字段

在某些特殊使用情况下（可能并不常见），您可能希望将表单字段**限制**为仅在 Pydantic 模型中声明过的字段，并**禁止**任何**额外**的字段。

/// note

自 FastAPI 版本 `0.114.0` 起支持此功能。🤓

## Die Dokumentation testen { #check-the-docs }

Sie können die erforderlichen Header in der Dokumentationsoberfläche unter `/docs` sehen:

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

## Zusätzliche Header verbieten { #forbid-extra-headers }

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

You can see the required headers in the docs UI at `/docs`:

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

## Forbid Extra Headers { #forbid-extra-headers }

In some special use cases (probably not very common), you might want to **restrict** the headers that you want to receive.

**FastAPI**는 요청의 **쿼리 매개변수**에서 **각 필드**의 데이터를 **추출**해 정의한 Pydantic 모델로 제공합니다.

## 문서 확인하기

`/docs` 경로의 API 문서에서 매개변수를 확인할 수 있습니다.

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

## 추가 쿼리 매개변수 금지

몇몇의 특이한 경우에 (흔치 않지만), 허용할 쿼리 매개변수를 **제한**해야할 수 있습니다.

Pydantic 모델 설정에서 `extra` 필드를 `forbid` 로 설정할 수 있습니다.

## Untrusted inputs during training and prediction

TensorFlow supports a wide range of input data formats. For example it can
process images, audio, videos, and text. There are several modules specialized
in taking those formats, modifying them, and/or converting them to intermediate
formats that can be processed by TensorFlow.
