How to build a Facebook app with PHP that shows albums?

问题

I want to build a Facebook web application that uses the graph API to show only the albums of a specific user. That user is always the same, and I know his credentials.

My code so far:

$this->facebook->api("username/albums?access_token=" . $this->access_token);

But I get the following exception:

[error] => Array
(
    [message] => A user access token is required to request this resource.
    [type] => OAuthException
    [code] => 102
)

I need to generate an acces_token that lives forever and is able to retrieve this information, because right now I can only access public data. Where do I have to start?

回答1:

When you have a registered app you can generate an app access token which is always valid.

Use this URL to get your access token:

https://graph.facebook.com/oauth/access_token?
    client_id=YOUR_APP_ID
   &client_secret=YOUR_APP_SECRET
   &grant_type=client_credentials

You can find the App id and App secret on your apps page.
Please note that the albums and/or photos you see depend on the privacy settings of the albums/photo/
