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。

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

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

JProperty可以获取到JToken或者JObject的属性名。

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

下面来写一个测试的例子。

Json数据如下:

{"skeleton":{"images":""},
    "bones":[{"name":"root"}],
    "skins":{
    	"default":{
    	},
    	"base":{
    		"hair":{"hair":{"name":"base/hair", "x":1424,"y":2564.5,"width":1132,"height":1177}},
    		"h_r":{"h_r":{"name":"base/h_r", "x":1166.5,"y":1955,"width":313,"height":280}},
    		"0":{"0":{"name":"base/0", "x":1455.5,"y":1468.5,"width":2197,"height":2813}},
    		"00":{"00":{"name":"base/00", "x":1421.5,"y":2065.5,"width":703,"height":117}}
    	},
    	"mouth":{
    		"m_light":{"m_light":{"name":"mouth/m_light", "x":1415,"y":1616.5,"width":178,"height":115}},
    		"m_2":{"m_2":{"name":"mouth/m_2", "x":1417.5,"y":1574,"width":331,"height":102}},
    		"m_1":{"m_1":{"name":"mouth/m_1", "x":1420,"y":1639,"width":324,"height":68}}
    	},
    	"eye_ball":{
    		"e_l":{"e_l":{"name":"eye_ball/e_l", "x":1673,"y":2056.5,"width":112,"height":103}},
    		"e_r":{"e_r":{"name":"eye_ball/e_r", "x":1404.5,"y":2055,"width":571,"height":100}}
    	},
    	"hair":{
    		"h_1":{"h_1":{"name":"hair/h_1", "x":1463.5,"y":1511.5,"width":1897,"height":2901}}
    	}
    },
    "animations":{"animation":{}}
    }

目标要读取skins里的数据

static string SpritePath(string url)
        {
            return Application.dataPath +"/"+ url;
        }
    
        //1536 * 2268
        //(768 , 1134)
        static Vector2 SpriteSize = new Vector2(1536f, 2268f);
        static Vector2 SpriteCenter = SpriteSize * 0.5f;
        static int SpriteScale = 100;
        static string spath = "";
        [MenuItem("工具/生成模板")]
        static void ImportDresserMask()
        {
            //首先读取json 
    
            string dataPath;//= System.IO.Path.GetFullPath(".");
            dataPath = SpritePath("AssetAll/ps/1") ;
            string fullPath = dataPath+ "/1.json";
    
            GameObject objRoot = new GameObject("root");
            objRoot.transform.localPosition = Vector3.zero;
    
    
            if (File.Exists(fullPath))
            {
                StreamReader sr = new StreamReader(fullPath, System.Text.Encoding.UTF8);
                string jsonStr = sr.ReadToEnd();
                sr.Close();
    
                JObject obj = (JObject)JsonConvert.DeserializeObject(jsonStr);
                JObject state = (JObject)obj["skins"];  //获取skins里的数据
                //foreach (JToken item in state.Values())
                int order = 0;
                foreach (JProperty item in state.Properties())
                {
                    string pkey = item.Name;
                    
                    Debug.Log("分类:" + pkey);
                    JToken tok = state[pkey];
                    if (tok.HasValues)
                    {
                        GameObject objclass = new GameObject(pkey);
                        objclass.transform.SetParent(objRoot.transform);
                        objclass.transform.localPosition = Vector3.zero;
    
                        //循环所有属性
                        foreach (JProperty jp in tok)
                        {
                            order++;
                            string k = jp.Name;
                            JToken v = jp.Value;
                            JObject o = (JObject)v[k];
    
                            GameObject ob = new GameObject(k);
                            ob.transform.SetParent(objclass.transform);
                            Vector2 at = (new Vector2((float)o["x"], (float)o["y"]) - SpriteCenter)/ SpriteScale;
                            ob.transform.localPosition = at;
                            SpriteRenderer spriteRenderer = ob.AddComponent<SpriteRenderer>();
                            spriteRenderer.sortingOrder = order;
    
                            string imgPath = dataPath + "/" + o["name"] + ".png";
                            //Texture2D myTexture = new Texture2D(1, 1);
                            //myTexture.LoadImage(System.IO.File.ReadAllBytes(imgPath));
                            //myTexture.Apply();
                            //Sprite sp = Sprite.Create(myTexture, new Rect(0f, 0f, myTexture.width, myTexture.height), new Vector2(0.5f, 0.5f));
                            Sprite sp = AssetDatabase.LoadAssetAtPath<Sprite>(imgPath);
                            spriteRenderer.sprite = sp;
    
                            Debug.Log(k+" - "+o["name"]+","+o["width"] );
                        }
                    }
                }
            }
        }

输出结果

hair - base/hair,1132
    h_r - base/h_r,313
    0 - base/0,2197
    00 - base/00,703
    m_light - mouth/m_light,178
    ..........
