从 JSONArray 获取点赞数据（id 和名称） - Facebook api

Question

我正在尝试从 Android 上 facebook graph api 中的点赞数据中获取 id 和 named:

{
   "data": [
      {
         "id": "1433908706707486_917483885016640"
      },
      {
         "id": "1433908706707486_910831695681859"
      },
      {
         "id": "1433908706707486_906550586109970",
         "likes": {
            "data": [
               {
                  "id": "xxxx",
                  "name": "xxx"
               }
            ],
            "paging": {
               "cursors": {
                  "before": "MTEwNTU0NTg3OTQ2NjE3NgZDZD",
                  "after": "MTEwNTU0NTg3OTQ2NjE3NgZDZD"
               }
            }
         }
      },
      {
         "id": "1433908706707486_902931413138554",
         "likes": {
            "data": [
               {
                  "id": "xxx",
                  "name": "Muhammad Waseem"
               }
            ],
            "paging": {
               "cursors": {
                  "before": "NzI3NTMxNjA0MDA0MDA5",
                  "after": "NzI3NTMxNjA0MDA0MDA5"
               }
            }
         }
      },
      {
         "id": "1433908706707486_134266116671758"
      }
   ],
   "paging": {
      "previous": "https://graph.faceb....",
      "next": "https://graph.faceb...
   }
}

问题出在这里：

我已经批准了来自 facebook 的 user_posts 权限，并且我的代码只获取用户的墙贴，请帮助获取喜欢我帖子的 id 和名称。谢谢

Answer 1

试试这个

try {

        JSONObject resObject = new JSONObject("your response");
        JSONArray jsonArray = resObject.getJSONArray("data");

        for (int i = 0; i < jsonArray.length(); i++) {

            JSONObject jsonObject = jsonArray.getJSONObject(i);

            Log.i("ID", "-->" + jsonObject.getString("id"));
            Log.i("Likes", "-->" + jsonObject.getString("likes"));

            JSONObject jsonObjectlikes = jsonObject.getJSONObject("likes");

            JSONArray jsonArrayLikeData = jsonObjectlikes.getJSONArray("data");

            for (int j = 0; j < jsonArrayLikeData.length(); j++) {

                JSONObject jsonObjectlike = jsonArrayLikeData.getJSONObject(i);
                Log.i("Like ID", "-->" + jsonObjectlike.getString("id"));
                Log.i("Like Name", "-->" + jsonObjectlike.getString("name"));
            }


        }


    }
    catch (JSONException e)
    {
        // TODO Auto-generated catch block
        e.printStackTrace();
    }

Answer 2

JSONObject object = new JSONObject("YOUR_RESPONSE");
        if (object.has("data")) {
            JSONArray jaData = object.getJSONArray("data");
            for (int i = 0; i < jaData.length(); i++) {
                JSONObject likeObject = jaData.getJSONObject(i).getJSONObject("likes");
                JSONArray likeDeatilArray = likeObject.getJSONArray("data");
                for (int j = 0; j < likeDeatilArray.length(); j++) {
                    String id = likeDeatilArray.getJSONObject(j).optString("id");
                    String name =  likeDeatilArray.getJSONObject(j).optString("name");

                    Log.v("name -", id+" name -"+name);
                }
            }

        }

希望这会有所帮助..
