Question

我正在尝试从Azure AD系统中检索身份验证令牌。我已经尝试了许多不同的方法来配置async方法和await命令，但每次我收到错误“任务被取消”。

我的aspx页面中有async =“true”。

任何想法，我需要采取不同的做法，以获得成功的请求和检索令牌。

相同的代码在控制台应用程序中工作，因此，我假设问题与异步操作的发生方式有关。

我的代码如下：

Answer 1

ASP.NET中的

async void方法并不是一件好事。有关它的一些信息，请参阅https://www.hanselman.com/blog/TheMagicOfUsingAsynchronousMethodsInASPNET45PlusAnImportantGotcha.aspx。

我相信您的Login_Click方法应使用此行异步调用Authorize：

RegisterAsyncTask(new PageAsyncTask(Authorize(tentantID, clientId, secret)));

然后Login_Click应该返回void而不使用async关键字。

Answer 2

根据您的描述，我通过在.NET Framework 4.5上创建Web表单应用程序目标并引用Active Directory Authentication Library 3.13.8来测试此问题。根据您的代码，它可以按预期工作并部署到Azure Web App。这是我的git sample，您可以参考它并尝试找出它是否可以按预期工作。
