unity用json和服务器数据交互

第一种类型:服务器json数据是个对象

/// <summary>
    /// 获取用户信息初始化信息
    /// </summary>
    void InitUserMessage()
    {
        //服务器ip端口和传入参数
        string path = string.Format("{0}/GetUserInfo?UserId={1}", PublicJs.url_RequestPrefix, PublicJs.GUID);
        StartCoroutine(GetUserInfo(path));
    }
    /// <summary>
    /// 从服务器获取数据
    /// </summary>
    /// <param name="urlParh">服务器ip和端口</param>
    /// <returns></returns>
    IEnumerator GetUserInfo(string urlParh)
    {
        Debug.Log(urlParh);

        DownloadItem down = new DownloadItem(urlParh);
        yield return down.www;

        string wwwText = down.Text();
        Debug.Log(wwwText);
        if (string.IsNullOrEmpty(wwwText) == false)
        {
            var curUser = Json.Deserialize(wwwText) as Dictionary<string, object>;
            view.InitUserMessage(curUser["UserName"].ToString(), curUser["ClassName"].ToString(), curUser["Coins"].ToString());
        }
        else
        {
            Debug.Log("信息错误");
        }
    }

第二种类型:服务器数据是对象数组

IEnumerator RefreshUIData()
    {
        string urlPath = string.Format("{0}/GetTrends?", PublicJs.url_RequestPrefix);
        DownloadItem down = new DownloadItem(urlPath);
        yield return down.www;
        string wwwText = down.Text();
        Debug.Log(urlPath);
        Debug.Log(wwwText);
        List<object> listObject = Json.Deserialize(wwwText) as List<object>;

        foreach (var i in listObject)
        {
            Dictionary<string, object> row = i as Dictionary<string, object>;
            HYDTAts hydt = new HYDTAts();
            hydt.ID = row["ID"].ToString();
            hydt.Name = row["Title"].ToString();
            hydtList.Add(hydt);
        }

        //hydtList = CSVFileHelp.GetCsvHYDT();
        //Debug.Log(hydtList.Count);

        int tp = 0;
        ItemHYDT itemHYDT;
        GameObject obj;
        foreach (HYDTAts item in hydtList)
        {
            obj = NGUITools.AddChild(view.GridObj, view.ItemObj);
            obj.name = tp.ToString("D3");
            obj.AddComponent<UIDragScrollView>();
            obj.transform.localPosition = new Vector3(0, -50 * tp, 0);
            itemHYDT = obj.AddComponent<ItemHYDT>();
            itemHYDT.SetLabelText(item.Name);
            itemHYDT.BindValue(item);
            itemHYDT.OnClick += ItemHYDT_OnClick;
            tp++;
        }

        yield return 0;
    }
