Facebook Graph API访问令牌

Question

I've spent the several hours reading posts here, and following links (many of them dead) to developer.facebook.com.

How can I display my most recent FB post on my external website? I can do this by manually updating access token every couple of hours. Or I could ask my website visitors to log into facebook when they visit my website. Obviously neither is a desirable solution.

The best I've been able to find is Facebook's offline-access-removal instructions https://developers.facebook.com/roadmap/offline-access-removal/#extend_token . In order to proceed, it seems I need an App ID. I'm making quite a few assumptions that this is the right approach. Can anyone explicitly confirm that this effort will eventually work? Or do I need to look elsewhere?

Answer 1

You extend a short lived access-token for a long lived access token. The only person that needs to login is the user you want the data from. Then you save the access_token to a database with the expiry and retrieve when needed for everyone else. In short steps

• Load your SQL with the access_token structure
• Create a configuration file for the database
• Create helper functions for database actions such as connecting and querying
• Load the Facebook SDK for the administration view page (this is where you want the login action to get the access_token)
• Update the database with access_token retrieved
• Use the front end to select the access_token from the database

There is a detailed workout for a page display though it wouldn't be that hard to modify it for long lived access tokens

Answer 2

1. https://developers.facebook.com/docs/howtos/login/server-side-login/ follow all the steps.
2. https://developers.facebook.com/roadmap/offline-access-removal/#extend_token

The stumbling block for me is that the first page gives you sample scripts (PHP and Javascript), whereas the second page is the basic REST API. I used curl, and will probably create a shell script when my access token expires in 60 days. Someone with more cut&paste confidence than I have could do the whole thing with a browser.
