如何从litjson

Question

来自服务器的我的json文件是这样的：

{"status":"success","data":{"projectId":"572ca0cde163d","sensorId":"572ca2deea163b","createTime":1462514044,"updateTimeStamp":1462514044,"recognPicUrl":"http://192.168.1.115:8500/dddd.jpg","drawingModule":{"subjectTemplateId":"16","drawingUnits":[{"drawingUnitId":"572ca0c4f14c023cdeea163c",
"drawingResources":
[{"resourceUrl":"http://192.168.1.115:8300/dds.png","serviceProps":{},"resourceType":"IMG"}],"drawingComponentId":"1"}],
"templateConfig":{"isVertical":false}},"targetId":"ba0a0d83c657e49eb312"}}

如何读取值“isVertical”？

Answer 1

首先，您的Json 不有效。应该有一个＆＃39; :＆＃39;在"serviceProps"和{},之间。

以下是Json数据的固定版本。

{"status":"success","data":{"projectId":"572ca0cde163d","sensorId":"572ca2deea163b","createTime":1462514044,"updateTimeStamp":1462514044,"recognPicUrl":"http://192.168.1.115:8500/dddd.jpg","drawingModule":{"subjectTemplateId":"16","drawingUnits":[{"drawingUnitId":"572ca0c4f14c023cdeea163c",
"drawingResources":
[{"resourceUrl":"http://192.168.1.115:8300/dds.png","serviceProps":{},"resourceType":"IMG"}],"drawingComponentId":"1"}],
"templateConfig":{"isVertical":false}},"targetId":"ba0a0d83c657e49eb312"}}

要回答您的问题，您可以通过创建代表所有密钥的类轻松提取isVertical，然后从该类中提取isVertical。

Unity在 5.3 版本中添加Json原生支持。下面的解决方案要求你有5.3及以上，它应该工作。使用 5.4.0b13 进行测试，它的工作原理应该适用于 5.3 。

[System.Serializable]
public class ServiceProps
{
}

[System.Serializable]
public class DrawingResource
{
    public string resourceUrl;
    public ServiceProps serviceProps;
    public string resourceType;
}

[System.Serializable]
public class DrawingUnit
{
    public string drawingUnitId;
    public List<DrawingResource> drawingResources;
    public string drawingComponentId;
}

[System.Serializable]
public class TemplateConfig
{
    public bool isVertical;
}

[System.Serializable]
public class DrawingModule
{
    public string subjectTemplateId;
    public List<DrawingUnit> drawingUnits;
    public TemplateConfig templateConfig;
}

[System.Serializable]
public class Data
{
    public string projectId;
    public string sensorId;
    public int createTime;
    public int updateTimeStamp;
    public string recognPicUrl;
    public DrawingModule drawingModule;
    public string targetId;
}

[System.Serializable]
public class PlayerInfo
{
    public string status;
    public Data data;
}

读取isVertical Json值的代码：

void test()
{
    string messageFromServer = "";
    messageFromServer = "{\"status\":\"success\",\"data\":{\"projectId\":\"572ca0cde163d\",\"sensorId\":\"572ca2deea163b\",\"createTime\":1462514044,\"updateTimeStamp\":1462514044,\"recognPicUrl\":\"http://192.168.1.115:8500/dddd.jpg\",\"drawingModule\":{\"subjectTemplateId\":\"16\",\"drawingUnits\":[{\"drawingUnitId\":\"572ca0c4f14c023cdeea163c\",\r\n    \"drawingResources\":\r\n    [{\"resourceUrl\":\"http://192.168.1.115:8300/dds.png\",\"serviceProps\":{},\"resourceType\":\"IMG\"}],\"drawingComponentId\":\"1\"}],\r\n    \"templateConfig\":{\"isVertical\":false}},\"targetId\":\"ba0a0d83c657e49eb312\"}}";



     PlayerInfo playerInfo;
     playerInfo = new PlayerInfo();
     playerInfo.data = new Data();
     playerInfo.data.drawingModule = new DrawingModule();

     playerInfo.data.drawingModule.drawingUnits = new List<DrawingUnit>();

     for (int i = 0; i < playerInfo.data.drawingModule.drawingUnits.Count; i++)
     {
         playerInfo.data.drawingModule.drawingUnits[i].drawingResources = new List<DrawingResource>();
     }


     playerInfo.data.drawingModule.templateConfig = new TemplateConfig();


     playerInfo = JsonUtility.FromJson<PlayerInfo>(messageFromServer);
     Debug.Log("Status: " + playerInfo.status);
     Debug.Log("Vertical: " + playerInfo.data.drawingModule.templateConfig.isVertical);
 }

喜欢这个

// read your json data into a variable
var jsonData = {"status":"success","data":{"projectId":"572ca0cde163d","sensorId":"572ca2deea163b","createTime":1462514044,"updateTimeStamp":1462514044,"recognPicUrl":"http://192.168.1.115:8500/dddd.jpg","drawingModule":{"subjectTemplateId":"16","drawingUnits":[{"drawingUnitId":"572ca0c4f14c023cdeea163c",
                "drawingResources":[{"resourceUrl":"http://192.168.1.115:8300/dds.png","serviceProps"{},"resourceType":"IMG"}],"drawingComponentId":"1"}],
                "templateConfig":{"isVertical":false}},"targetId":"ba0a0d83c657e49eb312"}};   

//then read it like this
var isVertical = jsonData.templateConfig.isVertical

修改

这应该是你想要它的方式

bool isVertical = (bool)jsondata["drawingModule"]["templateConfig"]["isVertical"];
