Power BI,Angular和ADAL.JS

标签: angular access-token powerbi powerbi-embedded adal.js

我正在尝试将Power BI嵌入Angular应用程序中,我使用的是angular-adal4 npm软件包,它基于adal.js进行身份验证。

身份验证工作正常,应用程序正在检索令牌,但当我尝试使用该令牌嵌入Power BI报告时,我正在从Power BI服务中检索403错误。

我已经检查了应用程序在Azure中的权限是更正,我能够使用.NET库提取正确的令牌,并使用角度应用程序中的令牌代码嵌入工作。

我一直在阅读adal.js库,我看到它正在发送一个带有response_type" id_token"的请求,我在.NET中使用的示例是发送一个response_type" code& #34;

经过大量的测试。我被困在这一点上。

我不确定我是否向adal.js发送了错误的配置,或者该库是否无法为Power BI检索正确的令牌

有人可以帮我解决这个问题吗?

我会很高兴任何建议/最佳实践分享。 谢谢!

确保Aad令牌具有正确的&#39; aud&#39;内部属性,以便它可以与powerbi / api端点通信......

此外,请确保您已在Azure门户中授予权限并在令牌中具有正确的范围,即您已为嵌入报表(Reports.Read.All)或仪表板(Dashboard.Read.All)添加了正确的权限。在Azure(或Power BI)中注册您的应用程序时
