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。

        // The actual daemon registry dir will be a subfolder using the name of the distribution.
        daemonRegistry = repoRoot().dir("build/daemon")
        gradleSnippetsDir = repoRoot().dir("platforms/documentation/docs/src/snippets") // TODO use dependency management
        distZipVersion = project.version.toString()
    }

    // Wire the different inputs for local distributions and repos that are declared by dependencies in the build scripts

例如，您可以有一个名为 `main.py` 的文件，其中包含以下内容：

```Python hl_lines="3"
import os

name = os.getenv("MY_NAME", "World")
print(f"Hello {name} from Python")
```

/// tip

<a href="https://docs.python.org/3.8/library/os.html#os.getenv" class="external-link" target="_blank">`os.getenv()`</a> 的第二个参数是要返回的默认值。

如果没有提供默认值，默认为 `None`，此处我们提供了 `"World"` 作为要使用的默认值。

///

然后，您可以调用该 Python 程序：
