Unity自带的json解析工具JsonUtility遇到的坑

json 字符串可以是json或txt文本文件，但保存必须是

如果是Utf-8有签名，简析就一直报错（本人这儿遇到的第一个坑）
错误：ArgumentException: JSON parse error: Invalid value.
另外一个坑就是json字符串里的名字与C#里需要保持一致：

json 字符串：

{
"datainfo": [
{
"name": "text1",
"uitxture": "text1.jpg",
"mode": "text1+1",
"assetname": "text111111",
"type": 0,
"Scalenfo": {
"x": 1.5,
"y": 0.5,
"z": 0.5
}
},
{
"name": "text2",
"uitxture": "text2.jpg",
"mode": "text2+1",
"assetname": "text222222",
"type": 1,
"Scalenfo": {
"x": 0.5,
"y": 0.5,
"z": 0.5
}
}
]
}

C#解析json类：

using System.Collections;
using System.Collections.Generic;
using UnityEngine;using System;
using UnityEditor;
[Serializable]
public class jsoninfo {    
  public data[] datainfo;}
[Serializable]
public class data{   
 public string name;    
public string uitxture;   
 public string mode;   
 public string assetname;  
  public int type;   
 public Vector3 Scalenfo;
}
public class jsonJiexi : MonoBehaviour {     
 // Use this for initialization   
 void Start () {         
 StartCoroutine(getTxt());       
   }

    IEnumerator getTxt() {       
 WWW www = new WWW(@"file://"+Application.dataPath+@"/json.txt");      
  yield return www;     
   if (www.error!=null)     
   {            Debug.Log(www.error);            
yield return null;    
    }           
 Debug.Log(www.text);      
  string json = www.text.ToString();        Debug.Log(json);        jsoninfo d = JsonUtility.FromJson(json);
Debug.Log(d.datainfo[0].name);
Debug.Log(d.datainfo[1].name);
Debug.Log(d.datainfo[1].Scalenfo);
JsonUtility.FromJsonOverwrite(json, d);
}
}
