& # 39;权威# 39;参数名称:authority

我基于这个例子开发了我的mvc应用:https://github.com/AzureADSamples/WebApp-WebAPI-OpenIDConnect-DotNet

验证工作完美与Azure AAD，我可以看到用户登录:

然而，在下面的控制器中，我想打印出一些APP属性，我得到了上面的错误

'authority'应该是Uri格式的执行过程中发生了一个未处理的异常当前的web请求。请查看堆栈跟踪了解更多信息有关错误及其在代码中产生的位置的信息。

Exception Details: System。ArgumentException: 'authority'应该在参数名称:authority
