# 요청 예제 데이터 선언 { #declare-request-example-data }

여러분의 앱이 받을 수 있는 데이터 예제를 선언할 수 있습니다.

여기 이를 위한 몇 가지 방식이 있습니다.

## Pydantic 모델 속 추가 JSON 스키마 데이터 { #extra-json-schema-data-in-pydantic-models }

생성된 JSON 스키마에 추가될 Pydantic 모델을 위한 `examples`을 선언할 수 있습니다.

{* ../../docs_src/schema_extra_example/tutorial001_py310.py hl[13:24] *}

추가 정보는 있는 그대로 해당 모델의 **JSON 스키마** 결과에 추가되고, API 문서에서 사용합니다.

**FastAPI** 把 `OAuth2PasswordBearer` 识别为安全方案。因此，可以通过这种方式把它添加至 OpenAPI。

但 `OAuth2PasswordRequestForm` 只是可以自行编写的类依赖项，也可以直接声明 `Form` 参数。

但由于这种用例很常见，FastAPI 为了简便，就直接提供了对它的支持。

///

### 使用表单数据 { #use-the-form-data }

/// tip | 提示

`OAuth2PasswordRequestForm` 类依赖项的实例没有以空格分隔的长字符串属性 `scope`，但它支持 `scopes` 属性，由已发送的 scope 字符串列表组成。

本例没有使用 `scopes`，但开发者也可以根据需要使用该属性。

///

现在，即可使用表单字段 `username`，从（伪）数据库中获取用户数据。
