JObject遍历Json格式属性和值

经常在Unity里要写Json格式解析，固定的类直接写类解析就好。

  1. CData getParm = (CData )JsonConvert.DeserializeObject(result, typeof(CData));

动态的，不知道属性名的，总是忘了代码怎么写，放博客里记录下。

把字符串转化成JObject对象

  1. JObject obj = (JObject)JsonConvert.DeserializeObject(jsonStr);

JProperty可以获取到JToken或者JObject的属性名。

  1. foreach (JProperty item in obj.Properties())
  2. //或者
  3. foreach (JProperty item in token)

下面来写一个测试的例子。

Json数据如下:

  1. {"skeleton":{"images":""},
  2. "bones":[{"name":"root"}],
  3. "skins":{
  4.     "default":{
  5.     },
  6.     "base":{
  7.         "hair":{"hair":{"name":"base/hair", "x":1424,"y":2564.5,"width":1132,"height":1177}},
  8.         "h_r":{"h_r":{"name":"base/h_r", "x":1166.5,"y":1955,"width":313,"height":280}},
  9.         "0":{"0":{"name":"base/0", "x":1455.5,"y":1468.5,"width":2197,"height":2813}},
  10.         "00":{"00":{"name":"base/00", "x":1421.5,"y":2065.5,"width":703,"height":117}}
  11.     },
  12.     "mouth":{
  13.         "m_light":{"m_light":{"name":"mouth/m_light", "x":1415,"y":1616.5,"width":178,"height":115}},
  14.         "m_2":{"m_2":{"name":"mouth/m_2", "x":1417.5,"y":1574,"width":331,"height":102}},
  15.         "m_1":{"m_1":{"name":"mouth/m_1", "x":1420,"y":1639,"width":324,"height":68}}
  16.     },
  17.     "eye_ball":{
  18.         "e_l":{"e_l":{"name":"eye_ball/e_l", "x":1673,"y":2056.5,"width":112,"height":103}},
  19.         "e_r":{"e_r":{"name":"eye_ball/e_r", "x":1404.5,"y":2055,"width":571,"height":100}}
  20.     },
  21.     "hair":{
  22.         "h_1":{"h_1":{"name":"hair/h_1", "x":1463.5,"y":1511.5,"width":1897,"height":2901}}
  23.     }
  24. },
  25. "animations":{"animation":{}}
  26. }

目标要读取skins里的数据

  1. static string SpritePath(string url)
  2.     {
  3.         return Application.dataPath +"/"+ url;
  4.     }
  6.     //1536 * 2268
  7.     //(768 , 1134)
  8.     static Vector2 SpriteSize = new Vector2(1536f, 2268f);
  9.     static Vector2 SpriteCenter = SpriteSize * 0.5f;
  10.     static int SpriteScale = 100;
  11.     static string spath = "";
  12.     [MenuItem("工具/生成模板")]
  13.     static void ImportDresserMask()
  14.     {
  15.         //首先读取json 
  17.         string dataPath;//= System.IO.Path.GetFullPath(".");
  18.         dataPath = SpritePath("AssetAll/ps/1") ;
  19.         string fullPath = dataPath+ "/1.json";
  21.         GameObject objRoot = new GameObject("root");
  22.         objRoot.transform.localPosition = Vector3.zero;
  25.         if (File.Exists(fullPath))
  26.         {
  27.             StreamReader sr = new StreamReader(fullPath, System.Text.Encoding.UTF8);
  28.             string jsonStr = sr.ReadToEnd();
  29.             sr.Close();
  31.             JObject obj = (JObject)JsonConvert.DeserializeObject(jsonStr);
  32.             JObject state = (JObject)obj["skins"];  //获取skins里的数据
  33.             //foreach (JToken item in state.Values())
  34.             int order = 0;
  35.             foreach (JProperty item in state.Properties())
  36.             {
  37.                 string pkey = item.Name;
  39.                 Debug.Log("分类:" + pkey);
  40.                 JToken tok = state[pkey];
  41.                 if (tok.HasValues)
  42.                 {
  43.                     GameObject objclass = new GameObject(pkey);
  44.                     objclass.transform.SetParent(objRoot.transform);
  45.                     objclass.transform.localPosition = Vector3.zero;
  47.                     //循环所有属性
  48.                     foreach (JProperty jp in tok)
  49.                     {
  50.                         order++;
  51.                         string k = jp.Name;
  52.                         JToken v = jp.Value;
  53.                         JObject o = (JObject)v[k];
  55.                         GameObject ob = new GameObject(k);
  56.                         ob.transform.SetParent(objclass.transform);
  57.                         Vector2 at = (new Vector2((float)o["x"], (float)o["y"]) - SpriteCenter)/ SpriteScale;
  58.                         ob.transform.localPosition = at;
  59.                         SpriteRenderer spriteRenderer = ob.AddComponent<SpriteRenderer>();
  60.                         spriteRenderer.sortingOrder = order;
  62.                         string imgPath = dataPath + "/" + o["name"] + ".png";
  63.                         //Texture2D myTexture = new Texture2D(1, 1);
  64.                         //myTexture.LoadImage(System.IO.File.ReadAllBytes(imgPath));
  65.                         //myTexture.Apply();
  66.                         //Sprite sp = Sprite.Create(myTexture, new Rect(0f, 0f, myTexture.width, myTexture.height), new Vector2(0.5f, 0.5f));
  67.                         Sprite sp = AssetDatabase.LoadAssetAtPath<Sprite>(imgPath);
  68.                         spriteRenderer.sprite = sp;
  70.                         Debug.Log(k+" - "+o["name"]+","+o["width"] );
  71.                     }
  72.                 }
  73.             }
  74.         }
  75.     }

输出结果

  1. hair - base/hair,1132
  2. h_r - base/h_r,313
  3. 0 - base/0,2197
  4. 00 - base/00,703
  5. m_light - mouth/m_light,178
  6. ..........
  7. ..........
