反序列化Facebook照片结果

Question

我试图反序列化从FB请求返回的结果。 我设法通过Facebook使用以下两行来获取已经通过Facebook登录我的应用程序的用户的照片列表：

string meQueryString = "/me?fields=photos";
FB.API(meQueryString, Facebook.HttpMethod.GET,GetPhotosCallback );

抱着我的唯一问题是我无法弄清楚如何反序列化FBResult。

这是我的代码：

using UnityEngine;
using System.Collections;
using System.Collections.Generic;
using Facebook.MiniJSON;
using UnityEngine.UI;
using Facebook;
public class User_Photos : MonoBehaviour {

private static List<object>  PhotosData ;
//public string link;
 void Awake()
{
    FB.Init(SetInit, onHideUnity);
}

private void SetInit()
{
    Debug.Log("FB Init Done");
    if (FB.IsLoggedIn) {
        Debug.Log ("FB lOGGED iN");
    }else {
        //FBLogin();
    }
}

private void onHideUnity(bool isGameShown)
{
    if (!isGameShown) {
        Time.timeScale = 0;
    } else 
    {
        Time.timeScale = 1;
    }
}

string meQueryString = "/me?fields=photos";
public void FacebookLogin()
{
    Debug.Log("Facebook Login Part");
    FB.Login ("user_photos, user_about_me", LoginCallback);
}
void LoginCallback(FBResult result)
{
    if (FB.IsLoggedIn) {
        Debug.Log ("user Logged in, Know We try To get Photos ");
        GetPhotos();
    } else {
        Debug.Log(" user failed");
    }
}

void GetPhotos()
{
    //if (FB.IsLoggedIn) {
        Debug.Log("GetPhotos");
    FB.API(meQueryString, Facebook.HttpMethod.GET,GetPhotosCallback );
    //}
}

void GetPhotosCallback(FBResult GetPhotosCallbackResult)
{
    PhotosData = DeserializeJasonPhotos (GetPhotosCallbackResult.Text);

    Debug.Log ("hhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhh" + PhotosData);
    foreach (Text im in PhotosData) {
        Debug.Log (im);
    }

}

public static List<object> DeserializeJasonPhotos(string jsonString)
    {
    Debug.Log ("ghhhhhhhhhhhhhhhhhhhhhhggggg");

    var reponseobject = Json.Deserialize (jsonString) as Dictionary<string, object>;
    object PicturesH;
    var photos = new List<object>();
    if (reponseobject.TryGetValue ("data", out PicturesH)) {
        Debug.Log (" try get value");
        photos = (List<object>)(((Dictionary<string, object>)PicturesH) ["images"]);

        if (photos.Count > 0) {
            var photoDict = ((Dictionary<string, object>)(photos [1]));
            var photo = new Dictionary<string,string> ();
            photo ["source"] = (string)photoDict ["source"];

            Debug.Log (photoDict);



        }
        //foreach (string link in Photos) {
        //print( photo["source"]);
    } else {
          Debug.Log("faillllllllllllllllllllldddddddddddddddddddd");
     }

    return photos;
    //Debug.Log ("photossss");
}

}

这是FBresult
