最近因項(xiàng)目需求，必須得擼擼unity了， 寫點(diǎn)筆記，記錄記錄下， 在Android用Gson解析Json數(shù)據(jù)，用起來還是滿愉快的， 轉(zhuǎn)到Unity后，用了下SampleJson感覺太麻煩了，好的框架用爽了后，人就會(huì)變得也越懶，于是就想用其它更好用的框架，最終找到了unity5.3 以后 unity自己提供了一個(gè)JSON data的序列化與反序列化的類JsonUtility。</br>目前提供3個(gè)接口:

• FromJson
• ToJson
• FromJsonOverwrite

學(xué)Android 開發(fā)的朋友們肯定對(duì)Google的Gson不會(huì)陌生, 用起來是何等的爽， 這個(gè)Unity版的JsonUitlity應(yīng)該就仿照Gson寫的吧...
少bb了，it‘s time to show me the code，現(xiàn)在我要解析的這個(gè)json 數(shù)據(jù)如下:一個(gè)head， 一個(gè) body且包含一個(gè)數(shù)組bookList， 還有一個(gè)page

{
    "head": {
        "status": 200,
        "message": "ok"
    },
    "body": {
        "bookList": [
            {
                "id": 1000,
                "title": "吶喊",
                "author": "魯迅"
            },
            {
                "id": 1001,
                "title": "彷徨",
                "author": "魯迅"
            }
        ]
    },
    "page": {
        "index": 1,
        "size": 500
    }
}

注意 解析的對(duì)象必須要支持序列化即用[Serializable]標(biāo)記的類, 每個(gè)類的field 必須要與json的objecty一一相匹配，如： ResponseInfo的field body對(duì)應(yīng)Json對(duì)象的body

public class ResponseInfo<T>
 {       
     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<BookEntity> bookList;       
 }

public class Test : MonoBehaviour {
    string json;

    void Start () 
    {    
        //=== 構(gòu)造一個(gè)將對(duì)象序列化JsonUtility.ToJson的過程 ===//
        
        /// 初始化Head
        Head head = new Head();
        head.status = 200;
        head.message = "ok";
        
        /// 初始化Body
        BookInfo body = new BookInfo();
        
        List<BookEntity> bookList = new List<BookEntity>();
        BookEntity entity1 = new BookEntity();
        entity1.id = 1000;
        entity1.title = "吶喊";
        entity1.author = "魯迅";
        
        BookEntity entity2 = new BookEntity();
        entity2.id = 1001;
        entity2.title = "彷徨";
        entity2.author = "魯迅";
        
        bookList.Add(entity1);
        bookList.Add(entity2);
        
        body.bookList = bookList;
        
        /// 初始化 Page
        Page page = new Page();
        page.index = 2;        
        page.size = 500;
        
        /// 構(gòu)造 ReponseInfo
        ResponseInfo<BookInfo> info = new ResponseInfo<BookInfo>();  
        info.head = head;
        info.page = page;
        info.body = body;
        
        ////得到序列化的json
        json = JsonUtility.ToJson(responseInfo);
        
        //=== 將json通過JsonUtility.FromJson 反序列化 ===//
        ResponseInfo<BookInfo> responseInfo =JsonUtility.FromJson<ResponseInfo<BookInfo>>(json);

        /// ok， that's all
    }       
}

怎么樣，是不是比 MiniJson, SampleJson用起來方便^^

還有個(gè)接口JsonUtility.FromJsonOverwrite(json, myObject) ，暫時(shí)沒用過，以后再研究....
