                                new GraphRequest.Callback() {
                                    public void onCompleted(GraphResponse response) {
                                        System.out.println("photosResponse:"+response);  }
                                }
                        ).executeAsync();

样本回复：

{
  Response: responseCode: 200,
  graphObject: {
    "data": [
      {
        "created_time": "2018-01-02T14:30:19+0000",
        "id": "12345678"
      },
      {
        "created_time": "2017-12-30T11:44:26+0000",
        "id": "23456789"
      }]}}

并添加了这些权限

loginButton.setReadPermissions("email", "user_birthday", "user_posts", "user_photos");

我在完成图谱API后得到了答案

这是我的代码，以获取所有尺寸的脸书图片网址

注意：我们可以根据我们的要求添加或删除参数

    public void syncImagesToDB(String FBuserId) {
    if (FBuserId != null && FBuserId.length() > 0) {
        Bundle fb_params = new Bundle();
        fb_params.putString("fields", "id, name,created_time, link,images");
        final ArrayList<String> imageURL_list = new ArrayList<>();
        new GraphRequest(
                AccessToken.getCurrentAccessToken(),
                "/" + FBuserId + "/photos/uploaded",
                fb_params,
                HttpMethod.GET,
                new GraphRequest.Callback() {
                    public void onCompleted(GraphResponse response) {

                        System.out.println("photosResponse:" + response);
                        try {
                            JSONObject jsonObject = response.getJSONObject();
                            Log.e("jsonObject ", " -> " + jsonObject);
                            //JSONObject jsonObject = new JSONObject(String.valueOf(response));
                            JSONArray jsonArray_data = jsonObject.optJSONArray("data");
                            for (int i = 0; i < jsonArray_data.length(); i++) {
                                JSONObject album = null;
                                album = jsonArray_data.optJSONObject(i);
                                String id = album.optString("id");
                                String link = album.optString("link");
                                String created_time = album.optString("created_time");
                                JSONArray images_arr = album.optJSONArray("images");
                                if (images_arr.length() > 0) {
                                    JSONObject image_obj = images_arr.optJSONObject(0);
                                    String source_url = image_obj.optString("source");



                                    imageURL_list.add(source_url);

                                }
                                Bundle params1 = new Bundle();
                                params1.putString("fields", "id, name, link");
                            }
                            if (imageURL_list != null && imageURL_list.size() > 0) {


                            }

                            System.out.println("total uploaded images:" + imageURL_list.size());
                        } catch (Exception e) {
                            // TODO Auto-generated catch block
                            e.printStackTrace();
                        }
                    }
                }

        ).executeAsync();
    }
}
