Facebook永久访问令牌

Question

I am working as part of a team for a company that wishes to display the time of the last post on a dashboard for a Facebook post. This is for a webpage.

To do this, an access token is required.

The standard Facebook token lasts for 1-2 hours, before it becomes unusable. There is an option to exchange this temporary token for a longer-term version , which lasts 60 days (~2 months). Is there a token that is permanent? (ie. Has no expiry date).

EDIT

This is for a HTML page that has some PHP code to display the time of the last post for a specific Facebook profile.

EDIT2

This is the situation:

The company I am working for currently has a HTML page that has a lot of statistics such as weather, alerts, graphs and other JavaScript widgets on a page. I have been asked to display a little section that displays the time of the last post for a certain Facebook profile. To do this, should I build a 'Facebook App', or is there another better way to retrieve this information? Can I use the Facebook API to get the last post without creating a Facebook app?

Answer 1

As far as I know offline_access has been deprecated so there is no option to get permanent access_token . The longest one you can get lasts for 60 days.

If you want to show date of the last post for specific account (I suppose this is for viewers account) you can create Facebook app, ask for read_stream extended permission, check date of the last post and display it in one request (use JavaScript SDK).

You can fetch it last post with

/me/feed?limit=1
