UEdite 上传2张图片报错： 返回数据 code=614&error=file+exists
请问可以一次上传2张图片么？
string ret = Request.QueryString["upload_ret"];
ret = NULL

/// <summary>
    /// 上传回调函数
    /// </summary>
    /// <returns></returns>
    public JsonResult QiniuUploadCallBack()
    {
        string ret = Request.QueryString["upload_ret"];
        dynamic data = System.Web.Helpers.Json.Decode(DecodeFromBase64("UTF-8", ret));
        string key = data["key"];
        IList<Code> QiniuCode = codeService.GetCodes("QiNiuKey");
        Qiniu.Conf.Config.ACCESS_KEY = QiniuCode[0].Value; //"DAdzOacPUmolrT7RnB0XRVGnj0woF2haXjp0nx6x";
        Qiniu.Conf.Config.SECRET_KEY = QiniuCode[1].Value; // "3LBRNtfVo0Jk1Xc3G4mvP7ThWHA2V4chw1smmsp_";
        string Bucket = QiniuCode[2].Value; //"zyimg";
        string DOMAIN = QiniuCode[3].Value; // "img.zoyeo.com";

        string baseUrl = GetPolicy.MakeBaseUrl(DOMAIN, key);
        return Json(new { original = data["name"], w = data["w"], h = data["h"], url = baseUrl, state = "SUCCESS" }, JsonRequestBehavior.AllowGet);
    }

同时上传几张图片本来是没有问题的，但是如果文件名相同的话，是会返回{"614":"文件已存在"}的。
