Error : http query string is too long
我在mvc中使用下面的代码来下载Excel文件,但它显示错误查询字符串太长。
public ActionResult Download(string input)
{
Response.Clear();
Response.ClearHeaders();
Response.ClearContent();
Response.Buffer = true;
Response.AddHeader("Content-Disposition", "attachment; filename= download.xlsx");
Response.AddHeader("Content-Type", "application/Excel");
Response.ContentType = "application/vnd.ms-excel";
Response.WriteFile(input);
Response.End();
return Content(String.Empty);
}
This code works for me for PDF:
public FileStreamResult DownnloadPDF(int id)
{Document document = new Document();
MemoryStream stream = new MemoryStream();
PdfWriter pdfWriter = PdfWriter.GetInstance(document, stream);
pdfWriter.CloseStream = false;
document.Open();
formatPDF(document, model);
document.Close();
stream.Flush(); //Always catches me out
stream.Position = 0; //Not sure if this is required
return File(stream, "application/pdf", "title" + ".pdf");
}
I really think that your ActionResult will not work.
