我在本机用VS 2010调试上传控件FileUpload 时是没有问题的，但是上传到服务器后，总是提示上传失败，前端JS方法onUploadError(e)里的 "e"也不见有什么其它属性，请问这是用来搞笑的吗？

以下是我的上传后台代码：

bool flag = false;
string strMsg = string.Empty;
try
{
// 获得程序路径
string tempFile = Request.PhysicalApplicationPath;
//找到目标文件对象
HttpPostedFile uploadFile = Request.Files["Fdata"];
string cmd = Request.Params["cmd"];
// 如果有文件, 则保存到一个地址
string _json = Request.Params["data"];
string fid = Request.Params["fid"];
JArray ja = (JArray)JsonConvert.DeserializeObject(_json);
Maticsoft.BLL.major bll_major = new Maticsoft.BLL.major();
if (cmd == "addRow")
{
major _major = new major();
_major.key = ja[0]["key"].ToString();
_major.ctype = ja[0]["ctype"].ToString();
_major.text = ja[0]["text"].ToString();
_major.years = Convert.ToInt32(ja[0]["years"].ToString());
_major.nodetype = -1;
_major.fid = int.Parse(fid);
_major.logo = uploadFile.FileName;
flag = bll_major.Add(_major);
}
if (cmd == "updateRow")
{
int id = Convert.ToInt32(ja[0]["id"].ToString());
major _major = bll_major.GetModel(id);
_major.key = ja[0]["key"].ToString();
_major.ctype = ja[0]["ctype"].ToString();
_major.text = ja[0]["text"].ToString();
_major.years = Convert.ToInt32(ja[0]["years"].ToString());
_major.logo = uploadFile.FileName;
flag = bll_major.Update(_major);
}
if (flag)
{
if (uploadFile.ContentLength > 0)
{
string _path = Server.MapPath("/admin/usermanage/UploadImage/");
uploadFile.SaveAs(string.Format("{0}{1}", _path, uploadFile.FileName));
ImageClass.MakeThumbnail(_path + uploadFile.FileName, Server.MapPath(_path+"x" + uploadFile.FileName), 0, 60, "H", System.Drawing.Imaging.ImageFormat.Png);
}
}
}
catch (Exception ex)
{
strMsg = ex.Data+"\\n"+ex.Message+"\\n"+ex.InnerException;
}
Response.Write((strMsg == "" ? flag.ToString() : strMsg));
