从Node续订Facebook访问令牌

Question

In my Node application, I store in the DB a long-lived user facebook access token and run a cron periodically.

There's a way to renew that access token after the 60 days without asking the user to renew it in my mobile app? I use fbgraph node module to communicate with the graph API, so maybe there's a way to renew that token from the backend itself without going to the mobile app, ask for status and login again with the JavaScript SDK.

Answer 1

Tokens always need to be refreshed with user interaction, there is no way to auto-refresh them.

But you don´t need to login again, you just need to use this function to refresh the User Token: https://developers.facebook.com/docs/reference/javascript/FB.getLoginStatus/
