Get contact list from gmail, yahoo, hotmail
问题 I wish to write an API that can get the contacts list from Gmail, Yahoo and other e-mails. How can this be done? Are there already existing APIs for them or do I need to write PHP code to extract information? I need a referral system like DropBox has. Has anyone coded it themselves or is it available as open source? https://www.dropbox.com/referrals Please guide me in this regard. Any link or explanation will do the job. Thanks :) 回答1: Google has an API: http://code.google.com/intl/en/apis
