Question

我正在提取Facebook页面的帖子详细信息。我提取了特定页面的json，现在我必须得到该页面所有帖子的id。我怎么能用facebook4j来做呢。

private static String readpage(Reader rd) throws IOException 
{
StringBuilder sb = new StringBuilder();
int cp;
while ((cp = rd.read()) != -1) 
{
  sb.append((char) cp);
}
return sb.toString();
}

public static JSONObject readurl(String url) throws IOException, JSONException
{
InputStream is = new URL(url).openStream();
try 
{
  BufferedReader rd = new BufferedReader(new InputStreamReader
(is, Charset.forName("UTF-8")));
  String jsonText = readpage(rd);
  JSONObject json = new JSONObject(jsonText);
  return json;
} 
finally
{
  is.close();
}
}
public static void main(String[] args) throws
IOException, JSONException, FacebookException
{ 
JSONObject json = readurl("https://graph.facebook.com/"+s);
}

您可以参考以下代码获取特定页面的所有帖子相关信息：

ResponseList<Post> results = facebook.getPosts(searchPost);

                    String userId = "";
                    for (Post post : results) {

                        obj.put("Post Id", post.getId());
                        obj.put("Post message", post.getMessage());
                        obj.put("No of likes on Post", post.getLikes().size());
                        obj.put("Post owner name:", post.getFrom().getName());
                        objArray = new JSONArray();

其中 obj 是一个JSON对象。

PS：我使用的是eclipse kepler和facebook4j-core-2.0.2
