一、UnityJson(Unity引擎自帶)
1.文本轉Json
//（item文本信息）
JsonUtility.ToJson(item))；
2.讀取Json文件
//<InFo_>轉化的類型，（jsonTex）Json文件
JsonUtility.FromJson<InFo__>(jsonTxt);
二、LitJson（借鑒大神）
1.下載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字符串顯示字典鍵值
public void ResolveJson()
{
//定義的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""
}
]
}";
//這里是解析，包括整形與字符串
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 然后在輸出
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"]);
}
}
