Nevertheless, you still enforce those scopes, or any other security/authorization requirement, however you need, in your code.

In many cases, OAuth2 with scopes can be an overkill.

But if you know you need it, or you are curious, keep reading.

## OAuth2 scopes and OpenAPI { #oauth2-scopes-and-openapi }

**FastAPI**는 개발자 여러분을 위한 편의성으로 `fastapi.responses`와 동일한 `starlette.responses`를 제공합니다. 그러나 사용 가능한 응답의 대부분은 Starlette에서 직접 제공됩니다. `status` 또한 마찬가지입니다.

///

## OpenAPI 및 API 문서

추가 상태 코드와 응답을 직접 반환하는 경우, FastAPI는 반환할 내용을 미리 알 수 있는 방법이 없기 때문에 OpenAPI 스키마(API 문서)에 포함되지 않습니다.

It would also mean that if you get data from the `Request` object directly (for example, read the body) it won't be validated, converted or documented (with OpenAPI, for the automatic API user interface) by FastAPI.

Although any other parameter declared normally (for example, the body with a Pydantic model) would still be validated, converted, annotated, etc.

它可以：

* 在响应中返回状态码
* 在 OpenAPI 概图（及用户界面）中存档：

<img src="/img/tutorial/response-status-code/image01.png">

/// note | 笔记

某些响应状态码表示响应没有响应体（参阅下一章）。

FastAPI 可以进行识别，并生成表明无响应体的 OpenAPI 文档。

///

## 关于 HTTP 状态码

/// note | 笔记

如果已经了解 HTTP 状态码，请跳到下一章。

///

在 HTTP 协议中，发送 3 位数的数字状态码是响应的一部分。

你也可以使用 `from starlette.responses import JSONResponse`。　

出于方便，**FastAPI** 为开发者提供同 `starlette.responses` 一样的 `fastapi.responses`。但是大多数可用的响应都是直接来自 Starlette。`status` 也是一样。

///

## OpenAPI 和 API 文档

如果你直接返回额外的状态码和响应，它们不会包含在 OpenAPI 方案（API 文档）中，因为 FastAPI 没办法预先知道你要返回什么。
