version `0.122.0`, they use the more appropriate HTTP status code `401 Unauthorized`, and return a sensible `WWW-Authenticate` header in the response, following the HTTP specifications, [RFC 7235](https://datatracker.ietf.org/doc/html/rfc7235#section-3.1), [RFC 9110](https://datatracker.ietf.org/doc/html/rfc9110#name-401-unauthorized).

But if for some reason your clients depend on the old behavior, you can revert to it by overriding the method `make_not_authenticated_error` in your security classes....

do FastAPI, eles usam o código de status HTTP `401 Unauthorized`, mais apropriado, e retornam um cabeçalho `WWW-Authenticate` adequado na response, seguindo as especificações HTTP, [RFC 7235](https://datatracker.ietf.org/doc/html/rfc7235#section-3.1), [RFC 9110](https://datatracker.ietf.org/doc/html/rfc9110#name-401-unauthorized).

Mas, se por algum motivo seus clientes dependem do comportamento antigo, você pode voltar a ele sobrescrevendo o método `make_not_authenticated_error` nas suas classes...

從 FastAPI 版本 `0.122.0` 起，改為使用更合適的 HTTP 狀態碼 `401 Unauthorized`，並在回應中依據 HTTP 規範加上合理的 `WWW-Authenticate` 標頭，參考 [RFC 7235](https://datatracker.ietf.org/doc/html/rfc7235#section-3.1)、[RFC 9110](https://datatracker.ietf.org/doc/html/rfc9110#name-401-unauthorized)。

但如果你的用戶端因某些原因依賴於舊行為，你可以在你的 security 類別中覆寫 `make_not_authenticated_error` 方法以恢復舊的行為。

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)。

しかし、何らかの理由でクライアントが従来の挙動に依存している場合は、セキュリティクラスでメソッド `make_not_authenticated_error` をオーバーライドすることで、その挙動に戻せます。
