Question

mvcsessionpost

Answer 1

有点想不通 为啥用POST.访问S控制器。
 直接windows.location.href="../down/Excel?auction=auction";
不可以？

Answer 3

        [HttpPost]
        public FileStreamResult DownLoad(MeteoDown auction)
        {
            MeteoDown md = auction;
         //.........
            MemoryStream ms = new MemoryStream();
            hssfworkbook.Write(ms);            string filename = DateTime.Now.ToString("yyyy-MM-dd") + ".xls";
            Response.ContentType = "application/vnd.ms-excel";
            Response.AddHeader("Content-Disposition", string.Format("attachment;filename={0}", filename));
            Response.Clear();                       MemoryStream ms = new MemoryStream();
            hssfworkbook.Write(ms);            string filename = DateTime.Now.ToString("yyyy-MM-dd") + ".xls";
            Response.ContentType = "application/vnd.ms-excel";
            Response.AddHeader("Content-Disposition", string.Format("attachment;filename={0}", filename));
            Response.Clear();            ms.WriteTo(Response.OutputStream);
            Response.End();
            byte[] fileDate=ms.ToArray();
            return new FileDown(filename, fileDate);
        }]
先谢谢insus,我看完你的代码，修改了后，再调试了一下，能够接收到post的数据，但是返回不了文件，好像是能接收就不能返回，是不是[HttpPost]的原因？
