为Azure移动应用程序网站登录指定重定向URL

Question

When the App Service has "Action to take when request is not authenticated" set to "Log in with X", any webpage hit gets sent to X for user login. Once the user logs in, the user is redirected to the page where they started.

For example, when the Social login service is Active Directory B2C, and the user starts from http://example.com/admin/monitor the user is sent to https://login.microsoftonline.com/...?...&state=redir%3D%252Fadmin%252Fmonitor

In this particular instance, I do not want all webpages to require authentication. How can I send a user to .auth/login/aad and specify the redirect_uri so that it comes back to the right page? If I do not specify anything, I end up at

and the website is only the originating website.

I am looking for something like https://example.com/.auth/login/aad?return_url=blahblah - I sure hope it exists!

Incidentally, there is a "redirect_uri" in aad that goes to /.auth/login/aad/callback. It looks like redirect_uri=https%3A%2F%2Fkamelos-app.azurewebsites.net%2F.auth%2Flogin%2Faad%2Fcallback. This is different than what I am talking about. After it goes to AAD, it goes to the Azure Mobile App and posts state=redir%3D%252Fadmin%252Fmonitor along with the token.

Update. I believe I am looking for "post_login_redirect_url"

You are looking for post_login_redirect_url I do not think there's a way to assign it from within a portal.
What you have to do instead is to navigate your users to

 /.auth/login/<provider>?post_login_redirect_url=YOUR_URL   

Your application can trigger the same redirect itself by navigating the user to the /.auth/login/ endpoint of your site, where is one of aad, facebook, google, microsoftaccount, and twitter

If writing additional code is not an option you can configure an advanced authentication with AAD (not sure about Google, facebook, etc)

And when you do that you can add post_login_redirect_url to a return url.
