使用 ASP.Net 核心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 核心控制台应用程序以使用 (this link) 将文件上传到 OneDrive 当我 运行 应用程序时，它要求在控制台中输入用户名和密码，所以我提供了我的 Azure 用户名和密码，但随后它显示错误“MsalServiceException：响应状态代码不指示成功：406（NotAcceptable）”，如图所示在图像中。我还在 appsettings.json 文件中提供了应用程序 ID 和租户 ID。 您知道为什么会出现此错误以及如何解决此错误吗？

Username/Password (ROPC) 不支持个人帐户。请参阅重要 here。

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。
