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： view plaincopyprint?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",""); WWW w = new WWW(" 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"]); } } } Server：

[plain] view plaincopyprint?using System; using System.Collections.Generic; using System.Linq; using System.Web; using System.Runtime.Serialization.Json; using System.ServiceModel; using System.ServiceModel.Web; using System.IO; namespace UpdatePhoto { /// <summary> /// GetPhotoList 的摘要说明 /// </summary> public class GetPhotoList : IHttpHandler { public void ProcessRequest(HttpContext context) { context.Response.ContentType = "text/plain"; string id = context.Request.Form["id"]; string path = context.Request.PhysicalApplicationPath; //context.Response.Write("Hello World"); List<Photo> photos = GetPhotos(id,path); DataContractJsonSerializer djson = new DataContractJsonSerializer(photos.GetType()); djson.WriteObject(context.Response.OutputStream, photos); } public List<Photo> GetPhotos(string id,string path) { //获取目录 string localPath = path&#;id &#; "\"; //读取目录下的文件 if (!Directory.Exists(localPath)) return null; string[] files = Directory.GetFiles(localPath); List<Photo> photos = new List<Photo>(); foreach (string file in files) { string filename = file.Substring(file.LastIndexOf('\')&#;1); Photo p = new Photo(); p.name = filename; p.id = id; photos.Add(p); } return photos; } public bool IsReusable { get { return false; } } } public class Photo { public string id; public string name; } }
