如何在服务器上保存Rotativa PDF

Question

我正在使用Rotativa在我的"MVC"应用程序中生成PDF.如何保存Rotativa PDF？所有过程完成后,我需要将文档保存在服务器上.

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 });            

} 

Answer 1

你可以尝试一下

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();

如果那样做不起作用,你可以按照这里的答案

只要确保你这样做就不要以PRVRequestPdfPDF视图的形式返回,而不是像上面那样的普通视图(只提到我自己犯了很多乐趣).

另一个有用的答案

我在这里找到了解决方案

            var actionPDF = new Rotativa.ActionAsPdf("YOUR_ACTION_Method", new { id = ID, lang = strLang } //some route values)
            {
                //FileName = "TestView.pdf",
                PageSize = Size.A4,
                PageOrientation = Rotativa.Options.Orientation.Landscape,
                PageMargins = { Left = 1, Right = 1 }
            };
            byte[] applicationPDFData = actionPDF.BuildPdf(ControllerContext);
