You can declare extra information in `Field`, `Query`, `Body`, etc. And it will be included in the generated JSON Schema.

You will learn more about adding extra information later in the docs, when learning to declare examples.

/// warning

Extra keys passed to `Field` will also be present in the resulting OpenAPI schema for your application.

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

## 문서 확인하기

문서 UI `/docs`에서 확인할 수 있습니다:

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

## 추가 폼 필드 금지하기

在一個 **Pydantic 模型**中聲明你需要的**查詢參數**，然後將參數聲明為 `Query`：

{* ../../docs_src/query_param_models/tutorial001_an_py310.py hl[9:13,17] *}

**FastAPI** 將會從請求的**查詢參數**中**提取**出**每個欄位**的資料，並將其提供給你定義的 Pydantic 模型。

## 查看文件

你可以在 `/docs` 頁面的 UI 中查看查詢參數：

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

## 禁止額外的查詢參數

在一些特殊的使用場景中（可能不是很常見），你可能希望**限制**你要收到的查詢參數。

    Our workaround is to tell GWT that util.concurrent and all other packages
    have prod supersource, even if they have none. GWT is happy to ignore us
    when we specify a nonexistent path.

    (I hope that this workaround does not cause its own problems in the future.)
