Google App Engine - How to get a list of all app administrators?

I want to programmatically retrieve a list of all the app administrators from within the app. However, I've found no APIs in User Service section that can accomplish this. Is t开发者_JAVA百科here any way or any undocumented API to do this?

No, there is not an API to programatically get a list of administrators for your app. However, you could create an augmented user model which includes extra information like this.

I'm not sure why you need a list of all admins, but if you just wanted to e-mail them then you could use the send_mail_to_admins() function.
