How to retrieve all email addresses in Facebook through API

问题

Facebook users can add multiple email addresses. I know, with the extended "email" permission, you can retrieve the primary email address through the graph API. How do you retrieve the rest of the email addresses? This is important for my app so that I can find their existing account in my database rather than unnecessarily creating a new account.

回答1:

The alternative email addresses are not available. They are not listed on the FQL table or the Graph API.
