unity请求json数据并解析

桃扇骨 2022-08-08 06:18 371阅读 0赞

unity3d在跟.net进行http通信的时候，最常见的就是表单数据的提交请求了，但服务器端会返回一坨json数据，这就要求我们在unity中进行json数据的处理了，一般unity中处理json个数数据用的最多的就是LitJSON(它是.net平台下处理SON数据库的类库)。下面我就贴出源码，仅供学习参考！

关于LitJSON的安装和使用，请参考：http://www.360doc.com/content/13/0117/11/10941785_260686840.shtml

或者参考：http://blog.csdn.net/dingxiaowei2013/article/details/17115665

将LitJson.dll放在assets目录下的plugins文件下，如果没有plugins文件就手动创建一个

Client：

using UnityEngine;
using System.Collections;
using LitJson;
public**class** GetPhotoList : MonoBehaviour {
// Use this for initialization
void Start () {
StartCoroutine(GetPhotos());
}
// Update is called once per frame
IEnumerator GetPhotos(){
WWWForm form = new WWWForm();
form.AddField(“id”,”123”);
WWW w = new WWW(“http://localhost:36944/GetPhotoList.ashx",form);
while (!w.isDone){yield return**new** WaitForEndOfFrame();}
if (w.error != null){Debug.LogError(w.error);}
Debug.Log(w.text);
JsonData jd = JsonMapper.ToObject(w.text);
for (int i = 0; i < jd.Count; i++)
{
Debug.Log(“id=” + jd[i][“id”]);
Debug.Log(“name=” + jd[i][“name”]);
}
}
}
