【Json】SimpleJson在项目中的使用

来源：互联网发布：csgo网络优化参数编辑：程序博客网时间：2024/05/21 00:01

具体代码可以查看：http://wiki.unity3d.com/index.php/SimpleJSON

推荐一个很好用的 json 解析网站：http://www.bejson.com/

使用SimpleJson 只需要把脚本导入即可

解析Json 用WWW 读取路径或者服务器发送过来声明var 变量去承接

JSON.Parse(string json) 参数是一个string 类型

Parse:j就是解析的意思

private void RectPostMsg (string json){var N = JSON.Parse (json);string msg = N ["Message"];if (msg == "004") {UIManager.GetInstance ().ShowMessageBox ("园所码错误！");return;}if (msg == "OK") {string val = N ["Data"] ["OrganId"]; Debug.Log ("RectPostMsgOK:" + val);}}

其中这个 json 是以{ } 括号开头的所以直接用 N【XXX】【XXX】可以获取如果要是以 [ ] 开头怎么办呢？

public IEnumerator LoadJson (){WWW www = new WWW ("file:///" + Application.persistentDataPath + "/myjson.json");yield return www;if (www.error != null) {Debug.Log ("UIUpload1 error:" + www.error);} else if (www.isDone) {Debug.Log ("UIUpload1 isDone:" + www.text);my_Json = www.text;jsonData = JSON.Parse (my_Json);}}

同样也是WWW读取过来用JSONParse解析

只不过用的是jsonData 来承接 private JSONNode jsonData; 是一个JSONNode 类型

[    {        "id": "2",        "attribute": [            {                "number": "0",                "bl_Default": "false",                "bl_Active": "true",                "alpha": "1.0",                "bl_InterAble": "true"            },            {                "number": "1",                "bl_Default": "true",                "bl_Active": "false",                "alpha": "0.0",                "bl_InterAble": "false"            }        ]    }]

解析的是一个[ ] 开头的json

想得到这个value j就要这样写 jsonData [0] ["id"].Value 因为是以[ ] 开头表明就是一个数组因为json 本身就是数组套字典

要是合并起来的话也是一样的

[    {        "id": "1",        "attribute": [            {                "number": "0",                "bl_Default": "False",                "bl_Active": "True",                "alpha": "1",                "bl_InterAble": "True"            },            {                "number": "1",                "bl_Default": "False",                "bl_Active": "True",                "alpha": "1",                "bl_InterAble": "True"            }        ]    },    {        "id": "1",        "attribute": [            {                "number": "0",                "bl_Default": "False",                "bl_Active": "True",                "alpha": "1",                "bl_InterAble": "True"            },            {                "number": "1",                "bl_Default": "False",                "bl_Active": "True",                "alpha": "1",                "bl_InterAble": "True"            }        ]    },    {        "id": "2",        "attribute": [            {                "number": "0",                "bl_Default": "False",                "bl_Active": "True",                "alpha": "1",                "bl_InterAble": "True"            },            {                "number": "1",                "bl_Default": "True",                "bl_Active": "False",                "alpha": "0",                "bl_InterAble": "False"            }        ]    }]
