[英]Get information about a page using facebook4j
是否可以在about部分中获取页面信息的String
? 示例: https : //www.facebook.com/FacebookDevelopers这是信息:“使用Facebook构建,发展您的应用并从中获利。https://developers.facebook.com/ ”
我发现Facebook的图形API通过支持此Field
about
一上Page
。
预先感谢您的帮助!
最好的问候,多米尼克
您可以在下面的代码段中获取Java中的Facebook页面信息:
private static final String FacebookURL_PAGES = "me/accounts?fields=access_token,category,id,perms,picture{url},can_post,is_published,cover,fan_count,is_verified,can_checkin,global_brand_page_name,link,country_page_likes,is_always_open,is_community_page,new_like_count,overall_star_rating,name";
public List<FacebookPageModel> getPages(String accessToken) throws FacebookException, JSONException {
JSONObject posts = getBatch(accessToken,FacebookURL_PAGES);
Gson g =new Gson();
System.out.println(posts);
JSONArray postsData = posts.getJSONArray("data");
System.out.println(g.toJson(postsData));
return getPageList(postsData);
}
private JSONObject getBatch(String accessToken, String url) throws FacebookException{
Gson g = new Gson();
Facebook facebook = getFacebook(accessToken);
BatchRequests<BatchRequest> batch = new BatchRequests<BatchRequest>();
batch.add(new BatchRequest(RequestMethod.GET, url));
List<BatchResponse> results = facebook.executeBatch(batch);
BatchResponse result2 = results.get(0);
System.out.println(g.toJson(result2.asJSONObject()));
return result2.asJSONObject();
}
private Facebook getFacebook(String accessToken){
if(accessToken == null){
System.out.println("Access Token null while request for Facebook Instance !");
return null;
}
Facebook facebook = new FacebookFactory().getInstance();
