Question

最近我一直试图以JSON的形式从外部源获取一些数据。我使用的库是Newtonsoft.Json的统一分支。当我在计算机上运行项目时，它从外部源中提取数据，并将其转换为对象。我所创建的UI /文本元素应该显示从我的外部源中提取的数据，当我在我的主计算机上运行项目它没有问题并且数据显示没有问题，但当我将项目发送到我的Hololens，我的调试器获取数据，我可以从字面上看到数据是从外部源提取的，但数据不会出现在hololens上。任何人都可以告诉我如何解决这个问题吗？

我的代码如下：

using System;
using System.Collections;
using System.Collections.Generic;
using UnityEngine;
using UnityEngine.UI;
//using SimpleJSON;
using Newtonsoft.Json;

[System.Serializable]
public class TimeProperties
{
    public string Year { get; set; }
    public string Month { get; set; }
    public string Day { get; set; }
    public string Hour { get; set; }
    public string Minutes { get; set; }
    public string Seconds { get; set; }
}
[System.Serializable]
public class TimeClass
{
    public TimeProperties Time { get; set; }
}

public class test : MonoBehaviour
{
    string url = "http://172.16.24.135:8080";
    public Text year;
    public Text month;
    public Text day;
    public Text hour;
    public Text minutes;
    public Text seconds;

    private void Start()
    {
        StartCoroutine(UpdateValues());
    }

    IEnumerator PullJsonData()
    {
        Debug.Log("entered");

        WWW www = new WWW(url);
        yield return www;
        if(www.error != null)
        {
            print("There was an error getting the data: " + www.error);
            yield break;
        }
        string jsonstring = www.text;
        var data = JsonConvert.DeserializeObject<TimeClass>(jsonstring);
        Debug.Log(data.Time.Seconds);


        var jaren = data.Time.Year; //data["Year"].AsInt;
        var maanden = data.Time.Month;//data["Month"].AsInt;
        var dagen = data.Time.Day;//data["Day"].AsInt;
        var uren = data.Time.Hour;//data["Hour"].AsInt;
        var minuten = data.Time.Minutes;//data["Minutes"].AsInt;
        var seconden = data.Time.Seconds;//data["Seconds"].AsInt;
        year.text = "Year: " + jaren;
        month.text = "Month: " + maanden;
        day.text = "Days: " + dagen;
        hour.text = "Hours: " + uren;
        minutes.text = "Minutes: " + minuten;
        seconds.text = "Seconds: " + seconden;
    }

    IEnumerator UpdateValues()
    {
        while (true)
        {
            StartCoroutine(PullJsonData());
            yield return new WaitForSeconds(1);
        }
    }
}

我通过Visual Studio代码2017使用＆＃34;发布x86＆＃34;将它发送到我的hololens。我也收到以下错误：

(Filename: 'C:\buildslave\unity\build\artifacts/generated/Metro/runtime/DebugBindings.gen.cpp Line: 51)
    Display is Transparent

(Filename: C:\buildslave\unity\build\artifacts/generated/Metro/runtime/DebugBindings.gen.cpp Line: 51)
    There was an error getting the data:

(Filename: C:\buildslave\unity\build\artifacts/generated/Metro/runtime/DebugBindings.gen.cpp Line: 51)
    Failed to get spatial stage statics - can't retrieve or interact with boundaries! Error code: '0x80040154'.

    entered

(Filename: C:\buildslave\unity\build\artifacts/generated/Metro/runtime/DebugBindings.gen.cpp Line: 51)'

我每秒都从外部源获取JSON数据，因此运行后每秒都会显示在我的调试中：输入（这是类pulljsondata（）中的debug.log）。获取数据时出错：

(Filename: C:\buildslave\unity\build\artifacts/generated/Metro/runtime/DebugBindings.gen.cpp Line: 51)

我设法让一切正常。在我的UI上没有显示任何内容的原因是因为我使用来自github（https://github.com/Microsoft/MixedRealityToolkit-Unity）的MixedRealityToolkit v2017.2.1.2安装了带有Hololens工具包的Unity 2017.3f1。我是如何设法让它运作的？我删除了Unity 2017.3f1并安装了Unity 2017.2.1f1并安装了最新版本的MixedRealityToolkit，v2017.2.1.3。重新安装后，我尝试使用一些元素启动并运行，并正确地从外部URL中提取json数据。

无法将数据显示在我的HoloLens上
