# 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)。

# Использование старых статус-кодов ошибок аутентификации 403 { #use-old-403-authentication-error-status-codes }

До версии FastAPI `0.122.0`, когда встроенные утилиты безопасности возвращали ошибку клиенту после неудачной аутентификации, они использовали HTTP статус-код `403 Forbidden`.
