Question

是否有可能在about部分获取页面信息的String？示例：https://www.facebook.com/FacebookDevelopers 以下是信息：“使用Facebook构建，发展和利用您的应用获利。https://developers.facebook.com/”

我发现Facebook图表api通过Page上的Field about支持此功能。

提前感谢您的帮助！

祝你好运，星

您可以在以下代码段中获取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();
    facebook.setOAuthAppId(appId, appSecret);
    facebook.setOAuthPermissions("email,publish_stream, publish_actions");
    facebook.setOAuthAccessToken(new AccessToken(accessToken, null));

    return facebook;
}
