     class TestJsonItem{public  string Name="尼桑";public int Age=223;public float Height=176;public float Width=130;public bool Sex=false;public Dictionary<string, string> _scoreDic=new Dictionary<string, string>();public List<DateTime> _dateList=new List<DateTime>();public TestJsonItemChild child=new TestJsonItemChild();}public  class TestJsonItemChild{public string ChildName="GTR";public string ChlidAge="12";public List<string> strList=new List<string>();}

//接收消息void client_MqttMsgPublishReceived(object sender, MqttMsgPublishEventArgs e) {Debug.Log("Received: " + System.Text.Encoding.UTF8.GetString(e.Message)  );} 
//发送client.Publish(top1, System.Text.Encoding.UTF8.GetBytes("Sending from Unity3D!!!"), MqttMsgBase.QOS_LEVEL_EXACTLY_ONCE, true);
