Facebook: Refreshing long-lived access token automatically
问题 I'm storing long-lived access tokens for users of my application that have associated their Facebook accounts to it. Since the demise of the offline_access tokens, these long-lived tokens have an expiry date of "about 60 days." However, they can refresh themselves when the user interacts with Facebook. According to the documentation: These tokens will be refreshed once per day when the person using your app makes a request to Facebook's servers. If no requests are made, the token will expire
