Question

我有两个控制器，一个是api控制器，另一个是一个视图控制器，我想做的是从该视图控制器中的视图从api控制器生成PDF ...这可能吗，以及如何我会这样做吗？

API控制器-这是我要生成PDF的地方

public byte[] getReportsPDF(string community, string procedure)
{
            byte[] pdfBytes = new byte[] { };

            System.Web.Mvc.ControllerContext context = new System.Web.Mvc.ControllerContext();

            if(procedure == "GetProductionTasks")
            {
                var actionPDF = new Rotativa.ActionAsPdf("RedBluePDF", new { community = community, procedure = procedure })
            {
                    PageSize = Size.A4,
                    PageOrientation = Rotativa.Options.Orientation.Landscape,
                    PageMargins = { Left = 1, Right = 1 }
                };
                pdfBytes = actionPDF.BuildFile(context);
            }

            return pdfBytes;
}

视图控制器-这是我要生成的视图。

public ActionResult RedBluePDF(string community, string procedure)
{
    return View();            
}

尝试了很长时间后，终于设法解决了这个问题：

var controller = DependencyResolver.Current.GetService<ViewController>();
RouteData route = new RouteData();
route.Values.Add("action", "RedBluePDF");
route.Values.Add("controller", "ApiController");
ControllerContext newContext = new ControllerContext(new HttpContextWrapper(System.Web.HttpContext.Current), route, controller);

controller.ControllerContext = newContext;
controller.RedBluePDF(community, procedure);

我一直在尝试：

var controller = DependencyResolver.Current.GetService<ControllerB>();
controller.ControllerContext = new ControllerContext(this.Request.RequestContext, controller);

但这会给我错误的pdf，因为它将使用您当前的控制器（在本例中为API控制器）来调用ActionAsPdf()

贷记this answer
