Asp.net mvc 5 如何在服务器上保存PDF

我正在使用Rotativa在我的“MVC”应用程序中生成PDF。如何保存PDF？我需要在所有过程完成后将文档保存到服务器上

代码如下：

public ActionResult PRVRequestPdf(string refnum,string emid)
{
    var prv = functions.getprvrequest(refnum, emid);            
    return View(prv);

}
public ActionResult PDFPRVRequest()
{
    var prv = Session["PRV"] as PRVRequestModel;
    byte[] pdfByteArray = Rotativa.WkhtmltopdfDriver.ConvertHtml("Rotativa", "Approver", "PRVRequestPdf");
    return new Rotativa.ViewAsPdf("PRVRequestPdf", new { refnum = prv.rheader.request.Referenceno });            

}

你可以试试这个

var actionResult = new ActionAsPdf("PRVRequestPdf", new { refnum = prv.rheader.request.Referenceno, emid = "Whatever this is" });
var byteArray = actionResult.BuildPdf(ControllerContext);
var fileStream = new FileStream(fullPath, FileMode.Create, FileAccess.Write);
fileStream.Write(byteArray, 0, byteArray.Length);
fileStream.Close();

如果这不起作用，那么你可以按照答案来做

如果您这样做，请确保不要让

PRVRequestPdf

以PDF视图的形式返回，而要像上面那样返回一个普通视图（只提到我自己设法与它发生冲突，引起了很多乐趣）。

另一个有用的答案：

这是原版的

您只需尝试一下：

var fileName = string.Format("my_file_{0}.pdf", id);
var path = Server.MapPath("~/App_Data/" + fileName);
System.IO.File.WriteAllBytes(path, pdfByteArray );

您可以使用viewspdf实现这一点

[HttpGet]
public ActionResult SaveAsPdf(string refnum, string emid)
{
    try
    {
        var prv = functions.getprvrequest(refnum, emid);
        ViewAsPdf pdf = new Rotativa.ViewAsPdf("PRVRequestPdf", prv)
        {
            FileName = "Test.pdf",
            CustomSwitches = "--page-offset 0 --footer-center [page] --footer-font-size 8"
        };
        byte[] pdfData = pdf.BuildFile(ControllerContext);
        string fullPath = @"\\server\network\path\pdfs\" + pdf.FileName;
        using (var fileStream = new FileStream(fullPath, FileMode.Create, FileAccess.Write))
        {
            fileStream.Write(pdfData, 0, pdfData.Length);
        }
        return Json(new { isSuccessful = true }, JsonRequestBehavior.AllowGet);
    }
    catch (Exception ex)
    {
        //TODO: ADD LOGGING
        return Json(new { isSuccessful = false, error  = "Uh oh!" }, JsonRequestBehavior.AllowGet);
        //throw;
    }
}

这个解决方案也使用了丹尼尔的答案。@meJustAndrew是的，我知道这就是为什么我在答案的第一行引用了他的答案

[HttpGet]
public ActionResult SaveAsPdf(string refnum, string emid)
{
    try
    {
        var prv = functions.getprvrequest(refnum, emid);
        ViewAsPdf pdf = new Rotativa.ViewAsPdf("PRVRequestPdf", prv)
        {
            FileName = "Test.pdf",
            CustomSwitches = "--page-offset 0 --footer-center [page] --footer-font-size 8"
        };
        byte[] pdfData = pdf.BuildFile(ControllerContext);
        string fullPath = @"\\server\network\path\pdfs\" + pdf.FileName;
        using (var fileStream = new FileStream(fullPath, FileMode.Create, FileAccess.Write))
        {
            fileStream.Write(pdfData, 0, pdfData.Length);
        }
        return Json(new { isSuccessful = true }, JsonRequestBehavior.AllowGet);
    }
    catch (Exception ex)
    {
        //TODO: ADD LOGGING
        return Json(new { isSuccessful = false, error  = "Uh oh!" }, JsonRequestBehavior.AllowGet);
        //throw;
    }
}
