在IIS上发布时，带有Rotativa的MVC5应用程序不起作用

问题描述

我正在使用Rotativa将视图转换为PDF.它可以在我的本地计算机上运行，​​但是在IIS服务器上发布时会出现如下错误:

I am using Rotativa for convert the view to PDF. It works on my local but when published on IIS server it gives error as below:

源错误:

不确定服务器为什么显示控制器上下文的本地路径.我正在使用默认路由.我有什么需要修改的东西吗?

Not sure why the server is showing my local path for the controller context. I am using the default routing. Is there anything specifically that I need to modify?

这是我用来传递控制器的代码段:

Here is the code snippet that I use to pass the controller:

    ControllerContext context = new    ControllerContext(Request.RequestContext, this);
    var pdf = new ViewAsPdf2("ModelClass", model);
    byte[] pdfByteArray = pdf.GetByte(context);

这是GetByte的代码

Here is the code for GetByte

 public class ViewAsPdf2: PartialViewAsPdf
    {
     public ViewAsPdf2(string viewName, object model) : base (viewName, model) {
    }
     public byte[] GetByte(ControllerContext context)
     {
            base.PrepareResponse(context.HttpContext.Response);
            base.ExecuteResult(context);
            return base.CallTheDriver(context);
        }
     }

推荐答案

在进行了一些研究之后，我发现为我解决了Rotativa无法解决服务器问题的问题:

After doing some research here is what I found that resolved the Rotativa not working on server issue for me:

Rotativa用于生成PDF的wkhtmltopdk.exe使用以下DLL

The wkhtmltopdk.exe used by Rotativa to generate PDFs uses the following DLLs

MSVCP120.dll MSVCR120.dll

这两个dll是两个不同的可安装软件包的一部分:

These two dlls are part of two different install able packages:

1. MSVCP120.dll 附带了Visual C ++可再发行组件包，用于Visual Studio 2010 64位软件包

1. MSVCP120.dll comes with Visual C++ Redistributable Packages forVisual Studio 2010 64 bit package

和

1. MSVCR120.dll 附带了Visual C ++可再发行组件包，用于Visual Studio 2013 32位程序包

1. MSVCR120.dll comes with Visual C++ Redistributable Packages forVisual Studio 2013 32-bit package

如何检查Rotativa使用的dll是否在正确的位置?好像rotativa使用来自的dllC:\ Windows \ SysWOW64

How to check if the dlls used by rotativa are in right place or not?It looks like rotativa uses dlls fromC:\Windows\SysWOW64

确保以上文件夹中存在MSVCP120.dll和MSVCR120.dll.我之前是指C:\ Windows \ System32文件夹，但是那里的dll对我没有任何帮助，进一步加剧了混乱.

Make sure MSVCP120.dll and MSVCR120.dll are present in the above folder. I was referring to C:\Windows\System32 folder earlier but having the dlls there did not do any good to me and added further to the confusion.

希望这会有所帮助.
