You can use the website authorization interface of the public number development to get the user Access_token, OpenID, and then call the interface to obtain the user information to determine whether it has been concerned.

You need a "page authorization" service number (no public number), recognized and required certification, through the OAUTH2 authorized after the user can get all the information!
