关于前端:unity解析json-数据

1.应用JsonUtility解析

JsonUtility是unity自带的解析json的工具。

1.1具体应用创立一个解释数据的对象类

须要留神的是须要将每一个办法序列化，应用[System.Serializable]

using System.Collections;

using System.Collections.Generic;

using UnityEngine;

[System.Serializable]

public class LaneelDrivePathsData

{

/// <summary>/// /// </summary>public string type;/// <summary>/// /// </summary>public List<FeaturesItem1> features;

}

[System.Serializable]

public class Geometry1

{

/// <summary>/// /// </summary>public string type;/// <summary>/// /// </summary>public List<Listwww.cungun.com<double>> coordinates;

}

[System.Serializable]

public class Properties1

{

/// <summary>/// /// </summary>public string type;/// <summary>/// /// </summary>public int parentLaneElId;/// <summary>/// /// </summary>public int fromLaneElId;/// <summary>/// /// </summary>public int toLaneElId;

}

[System.Serializable]

public class FeaturesItem1

{

/// <summary>/// /// </summary>public string type;/// <summary>/// /// </summary>public Geometry1 geometry;/// <summary>/// /// </summary>public Properties1 properties;

}

1.2获取接送数据：

string jsonTest1 = File.ReadAllText(Application.dataPath + "/Resources/geojson_laneel_drive_paths_1603453072.json", Encoding.UTF8);

1.3解析:

LaneelDrivePathsData obj1 = JsonUtility.FromJson<LaneelDrivePathsData>(jsonTest1);

1.4打印后果:

foreach (var inter in obj1.features)

    {        Debug.Log("********************************************");        Debug.Log("features.type:" + inter.type);        Debug.Log("=======================================");        Debug.Log("features.properties.type:" + inter.properties.type);        Debug.Log("features.properties.parentLaneElId:" + inter.properties.parentLaneElId);        Debug.Log("features.properties.fromLaneElId:" + inter.properties.fromLaneElId);        Debug.Log("features.properties.toLaneElId:" + inter.properties.toLaneElId);        Debug.Log("=======================================");        Debug.Log("features.geometry.type:" + inter.geometry.type);        foreach (var coor in inter.geometry.coordinates)        {            Debug.Log("____________________________________");            foreach (var co in coor)            {                Debug.Log("features.geometry.coordinates:" + co);            }        }           }

1.5查看打印后果：

并没有齐全打印，通过查找看游戏的各种材料发现JsonUtility再解析[ [],[] ]这种格局的时候是有问题的，须要有一个“title”才能够。

2.应用Newtonsoft.Json解释json 数据

因为应用自带的JsonUtility是不能满足我业务需要的，于是持续调研发现这个是能够的。持续尝试。

2.1增加Newtonsoft.Json

关上Window->Asset Store->搜寻json->抉择JSON.NET For Unity

2.2获取数据

string jsonTest = File.ReadAllText(Application.dataPath + "/Resources/geojson_laneel_drive_paths_1603453072.json", Encoding.UTF8);

2.3编写数据类

using System.Collections;

using System.Collections.Generic;

using UnityEngine;

public class LaneelDrivePathsDataTest

{

/// <summary>/// /// </summary>public string type { get; set; }/// <summary>/// /// </summary>public List<FeaturesItem> features { get; set; }

}

public class Geometry

{

/// <summary>/// /// </summary>public string type { get; set; }/// <summary>/// /// </summary>public List<List<double>> coordinates { get; set; }

}

public class Properties

{

/// <summary>/// /// </summary>public string type { get; set; }/// <summary>/// /// </summary>public int parentLaneElId { get; set; }/// <summary>/// /// </summary>public int fromLaneElId { get; set; }/// <summary>/// /// </summary>public int toLaneElId { get; set; }

}

public class FeaturesItem

{

/// <summary>/// /// </summary>public string type { get; set; }/// <summary>/// /// </summary>public Geometry geometry { get; set; }/// <summary>/// /// </summary>public Properties properties { get; set; }

}

能够应用主动生成工具，将json数据增加进去一键生成数据类。地址：

2.4解析数据

LaneelDrivePathsDataTest obj = JsonConvert.DeserializeObject<LaneelDrivePathsDataTest>(jsonTest);

2.5打印解析的数据

foreach (var inter in obj.features)

    {        Debug.Log("********************************************");        Debug.Log("features.type:" + inter.type);        Debug.Log("=======================================");        Debug.Log("features.geometry.type:" + inter.geometry.type);        foreach (var coor in inter.geometry.coordinates)        {            Debug.Log("____________________________________" );            foreach (var co in coor)            {                Debug.Log("features.geometry.coordinates:" + co);            }        }        Debug.Log("=======================================");        Debug.Log("features.properties.type:" + inter.properties.type);        Debug.Log("features.properties.parentLaneElId:" + inter.properties.parentLaneElId);        Debug.Log("features.properties.fromLaneElId:" + inter.properties.fromLaneElId);        Debug.Log("features.properties.toLaneElId:" + inter.properties.toLaneElId);
