Unity请求URL，json解析数据

后台接口，输入课程id 请求下面的url ，获取json信息

远程请求URL获取的json内容格式，先贴出来

{
  "code": "200",
  "data": {
    "CourseNoticeList": [
      {
        "id": "1",
        "Title": "asdf",
        "Content": "fasdfasdfasdfasdf"
      },
      {
        "id": "2",
        "Title": "aaaaaa",
        "Content": "hhhhhaaaaa"
      },
      {
        "id": "4",
        "Title": "1",
        "Content": "1"
      },
      {
        "id": "6",
        "Title": "1",
        "Content": "21"
      },
      {
        "id": "11",
        "Title": "11111111",
        "Content": "11111"
      }
    ]
  },
  "msg": "操作成功",
  "success": true
}

加入LitJson.dll

根据json内容，创建courseStuNoticeData类，包含json里的详细内容

using System;
using System.Collections;
using System.Collections.Generic;
using LitJson;
using UnityEngine;

public class courseStuNoticeData
{
    public string id;
    public string Content;
    public string Title;

    public static List<courseStuNoticeData> DesJsonList(string json)
    {
        List<courseStuNoticeData> resourceDatas = new List<courseStuNoticeData>();
        JsonData data = JsonMapper.ToObject<JsonData>(json);

        foreach (JsonData jsonData in data)
        {
            courseStuNoticeData rd = DesJsonData(jsonData.ToJson());
            resourceDatas.Add(rd);
        }
        return resourceDatas;
    }

    public static courseStuNoticeData DesJsonData(string json)
    {
        //JsonObject jsonData = SimpleJson.SimpleJson.DeserializeObject<JsonObject>(json);
        JsonData jsonData = JsonMapper.ToObject<JsonData>(json);
        courseStuNoticeData rd = new courseStuNoticeData();
        //rd.id = Convert.ToString(jsonData["id"].ToString());
        if (jsonData["id"] != null)
        {
            rd.id = Convert.ToString(jsonData["id"].ToString());
        }
        if (jsonData["Content"] != null)
        {
            rd.Content = Convert.ToString(jsonData["Content"].ToString());
        }
        if (jsonData["Title"] != null)
        {
            rd.Title = Convert.ToString(jsonData["Title"].ToString());
        }
       
        return rd;
    }
}
