Rotativa.Netcore 在本地工作但在部署后不工作

Sha*_*Sha 2 c# rotativa asp.net-core

我在 ASP.NET Core 2.1.1 项目中使用最新的 Rotativa.NetCore 程序集。NuGet ( https://www.nuget.org/packages/Rotativa.AspNetCore v. 1.0.6 ) 在部署 (win2016) 上不起作用,但在本地运行 (win10)。

IIS 在部署时给出 404,错误日志 (stdout) 显示:

      An unhandled exception has occurred while executing the request.

这是“我的项目”来源

public IActionResult DownloadCertificate(int id)
{
    var model = getData(id);
    return new ViewAsPdf("PdfCertificate", model)
    {
        WkhtmlPath = "", // set the path to the Rotativa .exe files. works locally but not on deployment. 
        FileName = "Cert.pdf"
    };
}

我曾尝试更改WkhtmlPath"..\\Rotativa\\"但没有运气。

故障排除我发现这个:https ://stackoverflow.com/a/48166956/560784 - 显然 Rotativa 是针对 .NET Core 1.0 编译的:

这里有将 Rotativa.NetCore 从 .Net Core 1 更新到 .Net Core 2.0 的代码:https : //github.com/aaxelm/Rotativa.NetCore/pull/1/files? diff=split

因此,我下载了 Rotativa 源并相应地更新到 .NET core 2.0,引用了新程序集。问题仍然存在。

我也检查过权限。Rotativa 文件夹赋予 IIS_IUSRS 执行权限(运行 ApplicationPoolIdentity)。

我错过了什么?

我的本地文件夹结构:

c:\inetpub\myproject\myproject.dll + web.config 什么不是。c:\inetpub\myproject\Rotativa{wkhtmltoimage.exe, wkhtmltopdf.exe, wkhtmltox.dll}

我部署的文件夹结构:

c:\inetpub\sites\myproject\myproject.dll + web.config 什么不是。c:\inetpub\sites\myproject\wwwroot\(静态文件) c:\inetpub\sites\myproject\Rotativa{wkhtmltoimage.exe, wkhtmltopdf.exe, wkhtmltox.dll}

事实证明我需要安装Microsoft Visual C++ Redistributable 2017 (x86)- 在此处下载:https : //visualstudio.microsoft.com/vs/older-downloads/https://visualstudio.microsoft.com/downloads/

  1. 我恢复到官方 nuget(为了更容易的未来维护)https://www.nuget.org/packages/Rotativa.AspNetCore v. 1.0.6
  2. 我添加RotativaConfiguration.Setup(env, "..\\Rotativa\\");Startup.cs
  3. 我的最终代码如下所示:

代码:

public IActionResult DownloadCertificate(int id)
{
    var model = getData(id);
    return new ViewAsPdf("PdfCertificate", model)
    {
         FileName = "Cert.pdf"
    };
