如何解决使用AcquireTokenAsync函数无法获取Power BI令牌
我的ASP.NET MVC项目之一使用Power BI报表集成到页面中。在控制器中，我使用此代码来获取令牌。
var credential = new UserPasswordCredential("USERNAME","PASSWORD");
var authenticationContext = new AuthenticationContext("https://login.windows.net/common/oauth2/authorize/");
var authenticationResult = await authenticationContext.AcquiretokenAsync("https://analysis.windows.net/powerbi/api","APPLICATION_ID",credential).ConfigureAwait(false);
当代码到达AcquiretokenAsync函数时，它将引发此异常。感谢您的支持。
