netcore在本地工作,但部署后不工作

rotativa asp.net-core c#

Sha Dean Kuga · 技术社区 · 6 年前

我正在ASP.NET Core 2.1.1项目中使用最新的rotativa.net core程序集。裸体( https://www.nuget.org/packages/Rotativa.AspNetCore v.1.0.6)不适用于部署(win2016),但适用于本地(win10)。

部署时的IIS提供404,错误日志(stdout)显示:

fail: Microsoft.AspNetCore.Diagnostics.ExceptionHandlerMiddleware[1]
      An unhandled exception has occurred while executing the request.
System.Exception

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"
    };
}

我试过换衣服 WkhtmlPath 到 "..\\Rotativa\\" 但没有运气。

故障排除我发现: https://stackoverflow.com/a/48166956/560784 -显然rotativa是根据.NET核心1.0编译的:

这里有代码可以将rotativa.net core从.NET核心1更新为.NET核心2.0: https://github.com/aaxelm/Rotativa.NetCore/pull/1/files?diff=split

因此,我下载了rotativa源代码并相应地更新到.NET核心2.0,引用了新的程序集。问题仍然存在。

我也查过分期付款。Rotativa文件夹授予IIS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及其他内容。 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以及其他内容。 C:\inetpub\sites\myproject\wwwroot\(静态文件) C:\inetpub\sites\myproject\rotativa wkhtmltoImage.exe,wkhtmltopdf.exe, wkhtmltox.dll_

原来我需要的是安装 Microsoft Visual C++ Redistributable 2017 (x86) https://visualstudio.microsoft.com/downloads/

https://www.nuget.org/packages/Rotativa.AspNetCore
RotativaConfiguration.Setup(env, "..\\Rotativa\\"); 到 Startup.cs

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