罗塔蒂瓦BuildFile没有击中行动方法

Question

我的Controller类中有两种操作方法：

view

• SaveAsPDF:调用

1. DetailsAll :获取一些数据和显示，它应该将DetailsAll视图保存为pdf

我的问题是SaveAsPDF动作方法。在这里，我尝试使用Rotativa ActionAsPdf以及随后的BuildFile方法来生成和保存PDF。但是，在执行"BuildFile“行时，它没有击中我的DetailsAll操作方法中的断点，从而导致生成该PDF为空白。

你能帮我找出问题所在吗？

    [HttpGet]
    public ActionResult DetailsAll()
    {
        var selectionBuilder = builderFactory.GetGeocodeReportSelectionViewModelBuilder();
        var companyList = selectionBuilder.Build();

        List<GeocodeReportViewModel> viewModel = new List<GeocodeReportViewModel>();
        foreach(SelectListItem record in companyList.Companies)
        {
            var builder = builderFactory.GetGeocodeReportViewModelBuilder(int.Parse(record.Value));
            viewModel.Add(builder.Build());
        }
        var model = new AllGeocodeReportViewModel
        {
            GeocodeReports = viewModel
        };
        return View(model);
    }

    [HttpGet]
    public string SaveAsPDF()
    {
        var report = new ActionAsPdf("DetailsAll")
        {
            FileName = "OEM_GeocodeReport_" + System.DateTime.Now.ToString("MMYY") + ".pdf",
            PageSize = Size.A4,
            PageOrientation = Orientation.Landscape,
            PageMargins = { Left = 1, Right = 1 }
        };
        byte[] pdf = report.BuildFile(ControllerContext);
        System.IO.File.WriteAllBytes("C:\\" + report.FileName, pdf);
        return "true";
    }

经过广泛的搜索，终于发现了这个问题。我需要发送身份验证cookie以及BuildFile请求，这样才能正常工作。添加了以下代码，现在它正确地生成了PDF：

 public void SaveAsPDF()
    {
        var cookies = Request.Cookies.AllKeys.ToDictionary(k => k, k => Request.Cookies[k].Value);
        var report = new ActionAsPdf("DetailsAll")
        {
            FileName = "OEM_GeocodeReport_" + System.DateTime.Now.ToString("MMyy") + ".pdf",
            PageSize = Size.A4,
            PageOrientation = Orientation.Portrait,
            PageMargins = { Left = 3, Right = 3 },
            FormsAuthenticationCookieName = System.Web.Security.FormsAuthentication.FormsCookieName,
            Cookies = cookies
        };
        byte[] pdf = report.BuildFile(ControllerContext);
        System.IO.File.WriteAllBytes("C:\\" + report.FileName, pdf);            
    }
