Unity-Json（测量）

库文件：LitJson.dll

using LitJson; //对json操作的命名空间

ToJson(只使用了json数据串，未生成json文件)

public void setSpot()
{
        string dataJsonStr = "";
        JsonData data = new JsonData();

        JsonData data01 = new JsonData();
        data01["spotName"] = YiZhi01.GetComponent<XuanDian>().Tex_Name.text;
        data.Add(data01);

        JsonData data02 = new JsonData();
        data02["spotName"] = YiZhi02.GetComponent<XuanDian>().Tex_Name.text;
        data.Add(data02);

        for (int i = 1; i < DaiQiu_Fu.transform.childCount; i++)
        {
            JsonData datai = new JsonData();
            datai["spotName"] = DaiQiu_Fu.transform.GetChild(i).GetComponent<XuanDian>().Tex_Name.text;
            data.Add(datai);
        }

        //传入jsondata数据
        dataJsonStr = LitJson.JsonMapper.ToJson(data);
        Debug.Log(dataJsonStr);
        Application.ExternalCall("setSpot", dataJsonStr); //传网页
    }
}

ReadJson

1. 网页调用

Application.ExternalCall("getSpot");   网页getSpot调用ReadJsonText()

html：

var str
function getSpot(){
      u.getUnity().SendMessage("GUI","ReadJsonText","+str+");
}

public void ReadJsonText(string str)
    {  
        string jsonString = str;
        JsonData jd = JsonMapper.ToObject(jsonString);

        for (int i = 0; i < jd.Count; i++)
        {
            GameObject temp = Instantiate(PrefabCube, PrefabCube.transform.position, PrefabCube.transform.rotation) as GameObject;
            //名字
            temp.name = jd[i]["spotName"].ToString();
        }
    }

2.协程

IEnumerator ReadJsonText()
{
    WWW www = new WWW(url);
    while (!www.isDone)
    {
        Debug.Log("Wait");
        yield return new WaitForSeconds(0.01f);
    }
    if (www.error != null)
    {
        Debug.LogError(www.error);
    }
    yield return www;
    Debug.Log(www.text);

    string jsonString = www.text;
    jsonString = System.Text.Encoding.UTF8.GetString(www.bytes, 3, www.bytes.Length - 3);

    JsonData jd = JsonMapper.ToObject(jsonString);

    for (int i = 0; i < jd.Count; i++)
    {
        GameObject temp = Instantiate(PrefabCube, PrefabCube.transform.position, PrefabCube.transform.rotation) as GameObject;
        temp.name = jd[i]["spotName"].ToString();
    }
    www.Dispose();
}

using System.Collections;
using LitJson;  //对json操作的命名空间
using System.Text;
using System.IO;
using UnityEditor;

        //文件的名称
        strName = strPath + "/NewFile.json";

        ReadJson();
        ReadJsonFromFile();
        WriteJsonToFile(strPath, strName);

        //h.Name = "炎魔之王丶拉格纳罗斯";
        //h.ID = "1001";
        string jsonH = JsonMapper.ToJson(h);
        print(jsonH);
    }//end_Start    
    void Update ()
    {
        
    }//end_Update
