Graph API how get facebook page members/likes

With FB 2.6 API you can get total likes with fan_count field.

http://graph.facebook.com/cocacola/?fields=fan_count&access_token={value}

https://graph.facebook.com/cocacola/?fields=fan_count&access_token=#######

You can get the facebook page member likes using the field fan_count. But you have to pass page access token rather than the user access_token.

Facebook will not give you a list of users who like a page. You don't need this to create this app. You can get this data by querying publicly available insights data.

This URL will get you the raw data this app uses to create this graph:

https://graph.facebook.com/cocacola/insights/page_fans_country?access_token=XXXXXX

You can get this information with any valid access_token.
