在hololens

Question

我正在使用Unity进行渲染的Microsoft Hololens 3D应用程序。我从Web服务和本地文件中获取Json数据以进行某些设置。测试程序并没有给我任何错误，实际上工作得很好，但当我尝试在模拟器或真正的hololens上部署版本时，我得到以下错误。

    Exception thrown: 'Newtonsoft.Json.JsonReaderException' in Newtonsoft.Json.dll
JsonReaderException: Error reading JToken from JsonReader. Path '', line 0, position 0.
   at Newtonsoft.Json.Linq.JToken.ReadFrom(JsonReader reader, JsonLoadSettings settings)
   at Newtonsoft.Json.Linq.JToken.Parse(String json, JsonLoadSettings settings)
   at Assets.Scripts.CreateHyrarchy.Start()
   at Assets.Scripts.CreateHyrarchy.$Invoke0(Int64 instance, Int64* args)
   at UnityEngine.Internal.$MethodUtility.InvokeMethod(Int64 instance, Int64* args, IntPtr method) 
(Filename: <Unknown> Line: 0)

我认为这与以下几行代码有关。

string data = reader.ReadData(Globals.Globals.RESOURCEFILE);
            JToken jObject = JToken.Parse(data);

Globals为我提供了资源路径。

public static String RESOURCEFILE = Application.dataPath+"/Resources/pipeLayout.json";

最后我希望阅读的json文件看起来像这样。

{
  "layers":[
    {
      "type": "water",
      "size-multiplier": 2,
      "color": "#00f",
      "hidden": false
    },
    {
      "type": "gas",
      "size-multiplier": 1,
      "color": "yellow",
      "hidden": false
    },
    {
      "type": "riool",
      "size-multiplier": 5,
      "color": "#FF0000",
      "hidden": false
    }
  ]
}

当我调用一个也返回json字符串的服务时，我遇到了同样的问题。

他们都使用像这样的读者对象。

public String ReadData(String source){
        {
            //Open a call to a webservice
            using (WWW webClient = new WWW(source))
        {
                //Wait until call is completed
                while (!webClient.isDone)
                {
                    new WaitForSeconds(1f);
                }

                //Get the desired data out
                String json = webClient.text.ToString();
                return json;

        }

    }

我尝试按如下方式转换json数据

JObject jObject = JObject.Parse(json);

        //Open features array in the object
        foreach(JObject pipe in jObject["features"].ToArray())
        {
            //Parse JSON Object to Creator
            PipeLineCreator p = pipe.ToObject<PipeLineCreator>();
        }

和Json数据看起来像这样

{

"totalFeatures": 12,
"features": [
    {
        "type": "Feature",
        "id": "pijpleidingen.3",

                        4.4356,
                        51.1481
                    ]

                51.1481
            ]
        }
    },
    {
        "type": "Feature",
        "id": "pijpleidingen.8",
        "geometry": {
            "type": "MultiLineString",
            "coordinates": [

                    [
                        4.4362,
                        51.1474
                    ],
                    [
                        4.436,
                        51.1477
                    ],
                    [
                        4.4361,
                        51.1477
                    ]
                ]
            ]
        },
        "geometry_name": "geom",
        "properties": {
            "type": "gas",
            "diepte_cm": 100,
            "bbox": [
                4.436,
                51.1474,
                4.4362,
                51.1477
            ]
        }
    }
}

有人能解释我发生了什么吗？
