使用 ASP.Net Core 控制台应用程序将文件上传到 OneDrive

Question

我正在尝试使用下面的代码将文件上传到 OneDrive。 为此，我首先创建了 Azure AD 应用程序，然后创建了 ASP.Net Core 控制台应用程序以使用（ 此链接）将文件上传到 OneDrive 当我运行该应用程序时，它会在控制台中询问用户名和密码，所以我给了我的 Azure 用户名和密码，但随后显示错误“MsalServiceException：响应状态代码不指示成功：406（NotAcceptable）”，如图所示。 我还在 appsettings.json 文件中给出了应用程序 ID 和租户 ID。 您知道为什么会发生此错误以及如何解决此错误吗？

个人帐户不支持用户名/密码 (ROPC)。 请参阅此处的重要信息。

您需要使用工作或学校帐户（看起来像xxxxxxx@xxx.onmicrosoft.com ）而不是 gmail 或其他第三方邮箱登录。 您可以添加用户（导航到 Azure Active Directory -> 用户 -> 新用户 -> 创建用户），然后使用此登录。
