以前的知识 过久就会忘记，要多学习 多回顾才行啊。 这里的 JsonData对象 用Json映射后， 就成 了可操作的对象了，第一个层jd[0]是 json 最外层的，也是里面最大的"book_list":，第二层 jd[0][i]就是 book_list里面的｛｝，｛｝，｛｝。
第三层 jd[0][i]["bookname"]就是 存放的数据了。
{
"book_list":
[
{
"bookname" : "story1",
"bookurl" : "file://Users//Aikao//Desktop//Story//Unity_WorkSpace//book1.mp3",
"icon" : "file://Users//Aikao//Desktop//Story//Unity_WorkSpace//book1.jpg"
},
{
"bookname":"story3",
"bookurl" : "file://Users//Aikao//Desktop//Story//Unity_WorkSpace//book3.mp3",
"icon" : "file://Users//Aikao//Desktop//Story//Unity_WorkSpace//book8.jpg"
},
{
"bookname":"story3",
"bookurl" : "file://Users//Aikao//Desktop//Story//Unity_WorkSpace//book3.mp3",
"icon" : "file://Users//Aikao//Desktop//Story//Unity_WorkSpace//book8.jpg"
},
{
"bookname":"story3",
"bookurl" : "file://Users//Aikao//Desktop//Story//Unity_WorkSpace//book3.mp3",
"icon" : "file://Users//Aikao//Desktop//Story//Unity_WorkSpace//book10.jpg"
}
]，
"book_2t":
[
{
"bookname" : "story1",
"bookurl" : "file://Users//Aikao//Desktop//Story//Unity_WorkSpace//book1.mp3",
"icon" : "file://Users//Aikao//Desktop//Story//Unity_WorkSpace//book1.jpg"
},
{
"bookname":"story3",
"bookurl" : "file://Users//Aikao//Desktop//Story//Unity_WorkSpace//book3.mp3",
"icon" : "file://Users//Aikao//Desktop//Story//Unity_WorkSpace//book8.jpg"
},
{
"bookname":"story3",
"bookurl" : "file://Users//Aikao//Desktop//Story//Unity_WorkSpace//book3.mp3",
"icon" : "file://Users//Aikao//Desktop//Story//Unity_WorkSpace//book8.jpg"
},
{
"bookname":"story3",
"bookurl" : "file://Users//Aikao//Desktop//Story//Unity_WorkSpace//book3.mp3",
"icon" : "file://Users//Aikao//Desktop//Story//Unity_WorkSpace//book10.jpg"
}
]
}另外 如果需要 用到int float这些， 只要用int.Parse()，float.Parse() 就可以了
这种方法是 依赖于 ListJson的， Unity 官方 也提供了JsonUtility 只要using 一下就可以了
using UnityEngine;
[System.Serializable]
public class PlayerInfo
{
public string name;
public int lives;
public float health;
public static PlayerInfo CreateFromJSON(string jsonString)
{
return JsonUtility.FromJson<PlayerInfo>(jsonString);
}
// Given JSON input:
// {"name":"Dr Charles","lives":3,"health":0.8}
// this example will return a PlayerInfo object with
// name == "Dr Charles", lives == 3, and health == 0.8f.
}
如果 遇到 要读取 角色1 角色2 角色3 这样的数据时， 可能是还是需要ListJson吧
还可以用这种方法 读取。。。PlayerList[] lists = JsonMapper.ToObject< PlayerList[]>(json);
方法如下
using UnityEngine;
using LitJson;
[System.Serializable]
public class PlayerInfo
{
public string name;
public int lives;
public float health;
// Given JSON input:
// {"name":"Dr Charles","lives":3,"health":0.8}
// this example will return a PlayerInfo object with
// name == "Dr Charles", lives == 3, and health == 0.8f.
}
public class PlayerList
{
public List<PlayerInfo> playerList ;
}
public class Client:MonoBehaviour
{
void Start
{
PlayerList[] PlayerList=CreateFromJSON("Path");
}
public static PlayerList[] CreateFromJSON(string jsonString)
{
return PlayerList[] lists = JsonMapper.ToObject< PlayerList[]>(json);
}
}
