[Unity3d]u3d請求json數據并解析

unity3d在跟.net進行http通信的時候，最常見的就是表單數據的提交請求了，但服務器端會返回一坨json數據，這就要求我們在unity中進行json數據的處理了，一般unity中處理json個數數據用的最多的就是LitJSON(它是.net平臺下處理SON數據庫的類庫)。下面我就貼出源碼，僅供學習參考！

關于LitJSON的安裝和使用，請參考：http://www.360doc.com/content/13/0117/11/10941785_260686840.shtml

將LitJson.dll放在assets目錄下的plugins文件下，如果沒有plugins文件就手動創建一個

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"]);         }              } }

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 的摘要說明     /// </summary>     public class GetPhotoList : IHttpHandler     {          public void Proce***equest(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)         {             //獲取目錄             string localPath = path+id + "\\";              //讀取目錄下的文件             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;     } }
