Json的使用（二）UnityJson和LitJson的使用

一、UnityJson(Unity引擎自带)

1.文本转Json

//（item文本信息）

JsonUtility.ToJson(item))；

2.读取Json文件

//<InFo_>转化的类型，（jsonTex）Json文件

JsonUtility.FromJson<InFo__>(jsonTxt);

二、LitJson（借鉴大神）

1.下载LitJson.dll文件（https://github.com/okamura0510/LitJsonRuler/blob/master/Assets/LJR/Plugins/LitJson.dll）到Assets/Plugins下

2.解析

//解析JSON字符串显示字典键值

public void ResolveJson()

{

 

                 //定义的JSON字符串，注意JSON的格式

 

string str = @"

 

            {

 

                ""Name""     : ""yusong"",

 

                ""Age""      : 26,

 

                ""Birthday"" : ""1986-11-21"",

 

""Thumbnail"":[

 

{

 

           ""Url"":    ""http://xuanyusong.com"",

 

           ""Height"": 256,

 

           ""Width"":  ""200""

 

},

 

{

 

           ""Url"":    ""http://baidu.com"",

 

           ""Height"": 1024,

 

           ""Width"":  ""500""

 

}

 

 

 

]

 

            }";

 

//这里是解析，包括整形与字符串

 

JsonData jd = JsonMapper.ToObject(str);

 

Debug.Log("name = " + (string)jd["Name"]);

 

Debug.Log("Age = " + (int)jd["Age"]);

 

Debug.Log("Birthday = " + (string)jd["Birthday"]);

 

JsonData jdItems = jd["Thumbnail"];

 

 

 

for (int i = 0; i < jdItems.Count; i++)

 

{

 

Debug.Log("URL = " + jdItems[i]["Url"]);

 

Debug.Log("Height = " + (int)jdItems[i]["Height"]);

 

         Debug.Log("Width = " + jdItems[i]["Width"]);

 

}

 

} 3.合成JSON字符串，先合成 然后在输出 public void MergerJson() { StringBuilder sb = new StringBuilder ();         JsonWriter writer = new JsonWriter (sb);           writer.WriteObjectStart ();   writer.WritePropertyName ("Name");         writer.Write ("yusong");   writer.WritePropertyName ("Age");         writer.Write (26);   writer.WritePropertyName ("Girl");   writer.WriteArrayStart ();   writer.WriteObjectStart(); writer.WritePropertyName("name");         writer.Write("ruoruo");         writer.WritePropertyName("age");         writer.Write(24); writer.WriteObjectEnd ();   writer.WriteObjectStart(); writer.WritePropertyName("name");         writer.Write("momo");         writer.WritePropertyName("age");         writer.Write(26); writer.WriteObjectEnd ();   writer.WriteArrayEnd();   writer.WriteObjectEnd (); Debug.Log(sb.ToString ());   JsonData jd = JsonMapper.ToObject(sb.ToString ()); Debug.Log("name = " + (string)jd["Name"]); Debug.Log("Age = " + (int)jd["Age"]); JsonData jdItems = jd["Girl"]; for (int i = 0; i < jdItems.Count; i++) { Debug.Log("Girl name = " + jdItems[i]["name"]); Debug.Log("Girl age = " + (int)jdItems[i]["age"]); } }
