Unity5.3Json测试学习

一.unity5.3新增了生成json、解析json和重写json的api，这里简单下。

namespace UnityEngine{   //解析json用的工具类    public static class JsonUtility    {        //        // 摘要:        //     ///        //     通过一个json和一个指定的父节点类型，返回这个父节点类的实例        //     ///        //        // 参数:        //   json:        //     json格式的string字符串        //        //   type:        //     根结点类型        //        // 返回结果:        //     ///        //     <pre name="code" class="csharp"><span style="white-space:pre"></span>根节点类的实例

// /// [WrapperlessIcall] public static object FromJson(string json, Type type);

<span style="white-space:pre"></span>//上面的一个泛型方法        public static T FromJson<T>(string json);        //        // 摘要:        //     ///        //     制定一个根结点类，重写以这个根结点为基础的json        //     ///        //        // 参数:        //   json:        //     重写的json，即新的json字符串        //        //   objectToOverwrite:        //     需要重写的根结点类实例        [WrapperlessIcall]        public static void FromJsonOverwrite(string json, object objectToOverwrite);        //        // 摘要:        //     ///        //     将一个根结点为obj的“类树”解析为json字符串        //     ///        //        // 参数:        //   obj:        //     根类        //        //   prettyPrint:        //     If true, format the output for readability. If false, format the output for minimum        //     size. Default is false.        //        // 返回结果:        //     ///        //     json字符串        //     ///        public static string ToJson(object obj);        //        // 摘要:        //     ///        //     和上面一样，格式化是否格式化输出        //     ///        //        // 参数:        //   obj:        //     The object to convert to JSON form.        //        //   prettyPrint:        //     如果是true，格式化输出，如果不是，以最省略形式输出，就是json文件就是一行，没有换行        //        // 返回结果:        //     ///        //     The object's data in JSON format.        //     ///        [WrapperlessIcall]        public static string ToJson(object obj, bool prettyPrint);    }}

二.示例程序

JsonClass.cs 用于构建类结构

using System;using System.Collections.Generic;using System.Linq;using System.Text;[Serializable]public class University{    public string UniversityName;    //专业    public Specialty specialty;    //专业代号}[Serializable]public class Specialty{    public string SpecialtyName;    //人数    public int StudentCount;    //学生    public Student student1;    public Student student2;    public Student student3;}[Serializable]public class Student{    //学生姓名    public string StudentName;    //成绩    public int StudengScore;}

MyTestJson.cs 用于挂在GameObject中测试：

using UnityEngine;using System.Collections;public class MyTestJson : MonoBehaviour {// Use this for initializationvoid Start () {        string json = writeJson();        Debug.Log(json);        int firstStuNum = getFirstSpecialtyStuNums();        Debug.Log("第一个班级软加班有学生人数： " + firstStuNum + "个");                    }// Update is called once per framevoid Update () {}    //编写一个大学信息的json格式    public string writeJson()    {        University uni = new University();        uni.UniversityName = "qiongzhou";        uni.specialty = new Specialty()        {            SpecialtyName = "SoftWare",            StudentCount = 2,                                                         };        uni.specialty.student1 = new Student()        {            StudentName = "蛋蛋君",            StudengScore = 0        };        uni.specialty.student2 = new Student()        {            StudentName = "死羊君",            StudengScore = 59        };        string json =  JsonUtility.ToJson(uni);        return json;    }    public int getFirstSpecialtyStuNums()    {        University uni = new University();        uni = JsonUtility.FromJson<University>(writeJson());        int num = uni.specialty.StudentCount;        return num;    }

测试结果：

再测试下重写json的

public static void FromJsonOverwrite(string json, object objectToOverwrite);方法

源代码：

<pre name="code" class="csharp">using UnityEngine;using System.Collections;public class MyTestJson : MonoBehaviour {// Use this for initializationvoid Start () {        string json = writeJson();                    }// Update is called once per framevoid Update () {}    //编写一个大学信息的json格式    public string writeJson()    {        University uni = new University();        uni.UniversityName = "qiongzhou";        uni.specialty = new Specialty()        {            SpecialtyName = "SoftWare",            StudentCount = 2,                                                         };        uni.specialty.student1 = new Student()        {            StudentName = "蛋蛋君",            StudengScore = 0        };        uni.specialty.student2 = new Student()        {            StudentName = "死羊君",            StudengScore = 59        };        string json =  JsonUtility.ToJson(uni);        Debug.Log(json);        string newjson = writeJson2();        JsonUtility.FromJsonOverwrite(newjson, uni);        Debug.Log("修改后的json ：" + JsonUtility.ToJson(uni));        return json;    }       public string writeJson2()    {        University newuni = new University();        newuni.UniversityName = "HaiDa";        newuni.specialty = new Specialty()        {            SpecialtyName = "SoftWare",            StudentCount = 3,        };        newuni.specialty.student1 = new Student()        {            StudentName = "小鸟游",            StudengScore = 10        };        newuni.specialty.student2 = new Student()        {            StudentName = "乱入君",            StudengScore = 20        };        newuni.specialty.student3 = new Student()        {            StudentName = "凑数君",            StudengScore = 30        };        return JsonUtility.ToJson(newuni);    }}

测试结果：

从表面上看就是这样的，挺好用的，不用自己写格式化json了。恩恩
