10 Json(unity3D)

//写入json文档
注意事项：

1、在Asset下要有一个StreamingAssets文件夹
2、在文件夹内，有一个已创建好的json空文档
3、引入命名空间 using Litjson; using System; using System.IO;
4、创建英雄和技能类

Demo所需要的命名空间:

[Serializable]
class Hero
{
    public string HeroName;
    public string Hp;
    public string Attack;
    public List<Skill> Skills = new List<Skill> ();
}

[Serializable]
class Skill
{
    public string keyCode;
    public string Name;
    public string CD;
    public string MP;
}

void CreatJson ()
    {
        JsonData nuoke = new JsonData ();
        nuoke ["HeroName"] = "诺克";
        nuoke ["HP"] = ;
        nuoke ["Attack"] = ;
        nuoke ["Skills"] = new JsonData ();

        //一技能：大杀四方
        JsonData skill1 = new JsonData ();
        skill1 ["keyCode"] = "Q";
        skill1 ["Name"] = "大杀四方";
        skill1 ["CD"] = "9/8/7/6/5";
        skill1 ["MP"] = "";

        //二技能：致残打击
        JsonData skill2 = new JsonData ();
        skill2 ["keyCode"] = "W";
        skill2 ["Name"] = "致残打击";
        skill2 ["CD"] = "9/8/7/6/5";
        skill2 ["MP"] = "";

        //三技能：无情铁手
        JsonData skill3 = new JsonData ();
        skill2 ["keyCode"] = "E";
        skill2 ["Name"] = "无情铁手";
        skill2 ["CD"] = "24/21/18/15/12";
        skill2 ["MP"] = "";

        //大招：诺克萨斯断头台
        JsonData skill4 = new JsonData ();
        skill2 ["keyCode"] = "R";
        skill2 ["Name"] = "诺克萨斯断头台";
        skill2 ["CD"] = "120/100/80";
        skill2 ["MP"] = "100/100/0";

        //将生成的技能对象放到诺克的技能中
        nuoke ["Skills"].Add (skill1);
        nuoke ["Skills"].Add (skill2);
        nuoke ["Skills"].Add (skill3);
        nuoke ["Skills"].Add (skill4);

        //将生成的对象转化成json文档
        string json = JsonMapper.ToJson (nuoke);
        //将json写入到文件
        string path = Application.streamingAssetsPath + "/Nuoke.json";
        StreamWriter sw = new StreamWriter (path);
        sw.Write (json);
        sw.Close ();
    }

//解析json
    void PraseJson ()
    {
        FileInfo file = new FileInfo (Application.dataPath + "/StreamingAssets/Nuoke.json");
        StreamReader reader = new StreamReader (file.OpenRead (), Encoding.UTF8);
        string content = reader.ReadToEnd ();
        reader.Close ();
        reader.Dispose ();
        JsonData nuokeData = JsonMapper.ToObject (content);
        m_text.text = "英雄：" + nuokeData ["HeroName"] + "\n";
        //通过JsonData对象访问数据
        for (int i = ; i < nuokeData ["Skills"].Count; i++) {
            m_text.text += "技能：" + nuokeData ["Skills"] [i] ["Name"] + "\n技能键：\t" +
            nuokeData ["Skills"] [i] ["keyCode"] + "\nCD：\t" +
            nuokeData ["Skills"] [i] ["CD"] + "\nMP：\t" + nuokeData ["Skills"] [i] ["MP"] + "\n";
        }
    }

写入Json的中文会默认转化为UTF-8编码格式，在解析时，只需转换格式即可

unity3d使用litjson中文显示的问题 ，一下代码选至（https://www.cnblogs.com/fyluyg/p/5963052.html）
　　我们在使用litjson时它的编码方式是unicode的，所以我将json转成string输出时显示的是unicode的编码。这样我们显示或者保存中文时不是很方便。我们可以将中文的unicode转成能识别的GBK编码。

  using UnityEngine;
  using System.Collections.Generic;
  using Utils;
  using LitJson;
  using System;
  using System.Text.RegularExpressions;

  public class Script1 : MonoBehaviour
  {
     public void OnTestJson()
     {
         JsonData sData = new JsonData();
         JsonData data1 = new JsonData();
         JsonData data2 = new JsonData();

         data1["等级"] = "";
         data1["位置"] = "m=1000,x=33,y=21";   //新手村

         data2["等级"] = "";
         data2["位置"] = "m=1001,x=58,y=97";   //桃园镇

         sData["张三"] = data1;
         sData["李四"] = data2;

         string jsonStr = sData.ToJson();

         Regex reg = new Regex(@"(?i)\\[uU]([0-9a-f]{4})");
         var ss = reg.Replace(jsonStr, delegate(Match m) { return ((char)Convert.ToInt32(m.Groups[].Value, )).ToString(); });

         print(ss);
     }
 }
