# 이전 403 인증 오류 상태 코드 사용하기 { #use-old-403-authentication-error-status-codes }

FastAPI 버전 `0.122.0` 이전에는, 통합 보안 유틸리티가 인증 실패 후 클라이언트에 오류를 반환할 때 HTTP 상태 코드 `403 Forbidden`을 사용했습니다.

FastAPI 버전 `0.122.0`부터는 더 적절한 HTTP 상태 코드 `401 Unauthorized`를 사용하며, HTTP 명세인 [RFC 7235](https://datatracker.ietf.org/doc/html/rfc7235#section-3.1), [RFC 9110](https://datatracker.ietf.org/doc/html/rfc9110#name-401-unauthorized)를 따라 응답에 합리적인 `WWW-Authenticate` 헤더를 반환합니다.

# 使用旧的 403 认证错误状态码 { #use-old-403-authentication-error-status-codes }

在 FastAPI `0.122.0` 版本之前，当内置的安全工具在认证失败后向客户端返回错误时，会使用 HTTP 状态码 `403 Forbidden`。

从 FastAPI `0.122.0` 版本开始，它们改用更合适的 HTTP 状态码 `401 Unauthorized`，并在响应中返回合理的 `WWW-Authenticate` 头，遵循 HTTP 规范，[RFC 7235](https://datatracker.ietf.org/doc/html/rfc7235#section-3.1)、[RFC 9110](https://datatracker.ietf.org/doc/html/rfc9110#name-401-unauthorized)。

FastAPI バージョン `0.122.0` より前は、統合されたセキュリティユーティリティが認証に失敗してクライアントへエラーを返す際、HTTP ステータスコード `403 Forbidden` を使用していました。

FastAPI バージョン `0.122.0` 以降では、より適切な HTTP ステータスコード `401 Unauthorized` を使用し、HTTP 仕様に従ってレスポンスに妥当な `WWW-Authenticate` ヘッダーを含めます。[RFC 7235](https://datatracker.ietf.org/doc/html/rfc7235#section-3.1), [RFC 9110](https://datatracker.ietf.org/doc/html/rfc9110#name-401-unauthorized)。
