//json解析需要用到一个第三方dll文件

cities是键，json主要就是键值对

using UnityEngine;using System.Collections;using LitJson;public class NewBehaviourScript : MonoBehaviour {    string path = "http://api.dianping.com/v1/metadata/get_regions_with_businesses?appkey=1302010222&sign=D39143C2FAEE8DBF86E88DFAFF65D697D73B76A9&city=%E5%A4%A7%E8%BF%9E";void Start () {        StartCoroutine("MyJson",path);}void Update () {}    IEnumerator MyJson(string path)    {        WWW www = new WWW(path);        yield return www;        if (www.error==null)        {          //  print(www.text);            JsonData j = JsonMapper.ToObject(www.text);            JsonData city = j["cities"][0]["city_name"];//这个【0】代表的是json中第一个cities            JsonData neighborhoods = j["cities"][0]["districts"][0]["neighborhoods"][0];            print(neighborhoods);        }    }}
