在 Azure 中结合 Web 和移动应用程序时的身份验证

Question

I follow this article: develop-mobile-apps-with-csharp-and-azure for combining my already fonctional Xamarin app with an small web site use by some admins. In the article, we only need to add this in my web.config:

<authentication mode="Forms">
  <forms loginUrl="/.auth/login/aad" defaultUrl="/Home" timeout="480"/>
</authentication>

This addition work good, but after logging in and click on the ugly link "Return to you web site" provided by Azure, I always got redirect on the root of the site (that display: This mobile app is up and running). I try to add defaultUrl to redirect to the /Home page without success. Any idea?

You have probably not set the "Allowed External Redirect URLs". This feature allows you to call the authentication backend with a specific Redirect URL. On a successful authentication, it then redirects to one of the valid authentication redirects. You need to specify the url during the request by specifying a post_login_redirect_url . For example:

<forms loginUrl="/.auth/login/aad?post_login_redirect_url=/Home/Index" timeout="480"/>
