I'm wondering if there's a way to use the Facebook4J API to get all (or even recent) posts from a facebook page?
I know it's possible to get all posts from a user's wall or feed, but I can't find anything in the API or the documentation that shows how to get posts from a page.
Looking at http://facebook4j.org/en/api-support.html#page , it would appear that there is in fact a set of Page related methods, but clicking on any one of them simply refreshes the page, making me think that maybe they are planned but not yet implemented?
I know it's possible to get posts from a page using the graph API, but I'd really rather stick with Facebook4j, if possible.
Any input would be greatly appreciated!
Here is a minimal example for your problem: Note that you can get the access token and the page ID from https://developers.facebook.com/tools/explorer Use this id below in your code:
import facebook4j.Comment;
import facebook4j.Facebook;
import facebook4j.FacebookException;
import facebook4j.FacebookFactory;
import facebook4j.PagableList;
import facebook4j.Post;
import facebook4j.Reading;
import facebook4j.ResponseList;
import facebook4j.auth.AccessToken;
public class PostsFromPageExtractor {
/**
* A simple Facebook4J client which
* illustrates how to access group feeds / posts / comments.
*
* @param args
* @throws FacebookException
*/
public static void main(String[] args) throws FacebookException {
// Generate facebook instance.
Facebook facebook = new FacebookFactory().getInstance();
// Use default values for oauth app id.
facebook.setOAuthAppId("", "");
// Get an access token from:
// https://developers.facebook.com/tools/explorer
// Copy and paste it below.
String accessTokenString = "PASTE_YOUR_ACCESS_TOKEN_HERE";
AccessToken at = new AccessToken(accessTokenString);
// Set access token.
facebook.setOAuthAccessToken(at);
// We're done.
// Access group feeds.
// You can get the group ID from:
// https://developers.facebook.com/tools/explorer
// Set limit to 25 feeds.
ResponseList<Post> feeds = facebook.getFeed("187446750783",
new Reading().limit(25));
// For all 25 feeds...
for (int i = 0; i < feeds.size(); i++) {
// Get post.
Post post = feeds.get(i);
// Get (string) message.
String message = post.getMessage();
// Print out the message.
System.out.println(message);
// Get more stuff...
PagableList<Comment> comments = post.getComments();
String date = post.getCreatedTime().toString();
String name = post.getFrom().getName();
String id = post.getId();
}
}
}
Facebook4J supports Page APIs since version 2.0.
You can get posts from a facebook page via Facebook#getFeed(PAGE_ID).
example:
ResponseList<Post> feed = facebook.getFeed("eclipse.org");
