Unity5.3 JsonUtility的使用

最近因项目需求,必须得撸撸unity了, 写点笔记,记录记录下, 在Android用Gson解析Json数据,用起来还是满愉快的, 转到Unity后,用了下SampleJson感觉太麻烦了,好的框架用爽了后,人就会变得也越懒,于是就想用其它更好用的框架,最终找到了unity5.3 以后 unity自己提供了一个JSON data的序列化与反序列化的类JsonUtility。
目前提供3个接口:

  • FromJson
  • ToJson
  • FromJsonOverwrite

学Android 开发的朋友们肯定对Google的Gson不会陌生, 用起来是何等的爽, 这个Unity版的JsonUitlity应该就仿照Gson写的吧...
少bb了,it‘s time to show me the code,现在我要解析的这个json 数据如下:一个head, 一个 body且包含一个数组bookList, 还有一个page

{
    "head": {
        "status": 200,
        "message": "ok"
    },
    "body": {
        "bookList": [
            {
                "id": 1000,
                "title": "呐喊",
                "author": "鲁迅"
            },
            {
                "id": 1001,
                "title": "彷徨",
                "author": "鲁迅"
            }
        ]
    },
    "page": {
        "index": 1,
        "size": 500
    }
}
注意 解析的对象必须要支持序列化即用[Serializable]标记的类, 每个类的field 必须要与json的objecty一一相匹配,如: ResponseInfo的field body对应Json对象的body
public class ResponseInfo
 {       
     public T body;
     public Head head;
     public Page page;
 }

 [Serializable]
 public class Head
 {
     public string message;
     public int status;
 }

 [Serializable]
 public class Page
 {
     public int index;
     public int size;
 }
[Serializable]
public class BookEntity {  
    public int id;
    public string title;
    public string author;
}

[Serializable]
public class BookInfo
 {
     public List bookList;       
 }
public class Test : MonoBehaviour {
    string json;

    void Start () 
    {    
        //=== 构造一个将对象序列化JsonUtility.ToJson的过程 ===//
        
        /// 初始化Head
        Head head = new Head();
        head.status = 200;
        head.message = "ok";
        
        /// 初始化Body
        BookInfo body = new BookInfo();
        
        List bookList = new List();
        BookEntity entity1 = new BookEntity();
        entity1.id = 1000;
        entity1.title = "呐喊";
        entity1.author = "鲁迅";
        
        BookEntity entity2 = new BookEntity();
        entity2.id = 1001;
        entity2.title = "彷徨";
        entity2.author = "鲁迅";
        
        bookList.Add(entity1);
        bookList.Add(entity2);
        
        body.bookList = bookList;
        
        /// 初始化 Page
        Page page = new Page();
        page.index = 2;        
        page.size = 500;
        
        /// 构造 ReponseInfo
        ResponseInfo info = new ResponseInfo();  
        info.head = head;
        info.page = page;
        info.body = body;
        
        ////得到序列化的json
        json = JsonUtility.ToJson(responseInfo);
        
        //=== 将json通过JsonUtility.FromJson 反序列化 ===//
        ResponseInfo responseInfo =JsonUtility.FromJson>(json);

        /// ok, that's all
    }       
}

怎么样,是不是比 MiniJson, SampleJson用起来方便^^

还有个接口JsonUtility.FromJsonOverwrite(json, myObject) ,暂时没用过,以后再研究....
