使用 ASP.Net Core 控制台應用程序將文件上傳到 OneDrive

Question

我正在嘗試使用下面的代碼將文件上傳到 OneDrive。 為此，我首先創建了 Azure AD 應用程序，然后創建了 ASP.Net Core 控制台應用程序以使用（ 此鏈接）將文件上傳到 OneDrive 當我運行該應用程序時，它會在控制台中詢問用戶名和密碼，所以我給了我的 Azure 用戶名和密碼，但隨后顯示錯誤“MsalServiceException：響應狀態代碼不指示成功：406（NotAcceptable）”，如圖所示。 我還在 appsettings.json 文件中給出了應用程序 ID 和租戶 ID。 您知道為什么會發生此錯誤以及如何解決此錯誤嗎？

個人帳戶不支持用戶名/密碼 (ROPC)。 請參閱此處的重要信息。

您需要使用工作或學校帳戶（看起來像xxxxxxx@xxx.onmicrosoft.com ）而不是 gmail 或其他第三方郵箱登錄。 您可以添加用戶（導航到 Azure Active Directory -> 用戶 -> 新用戶 -> 創建用戶），然后使用此登錄。
