.使用JsonUtility解析
JsonUtility是unity自带的解析json的工具。
1.1具体使用创建一个解释数据的对象类
需要注意的是需要将每一个方法序列化，使用[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打印结果:
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查看打印结果：
并没有完全打印，经过查找看游戏的各种资料发现JsonUtility再解析[ [],[] ]这种格式的时候是有问题的，需要有一个“title”才可以。
2.使用Newtonsoft.Json解释json 数据
因为使用自带的JsonUtility是不能满足我业务需求的，于是继续调研发现这个是可以的。继续尝试。
2.1添加Newtonsoft.Json
打开Window->Asset Store->搜索json->选择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; } }
可以使用自动生成工具，将json数据添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); } }
