Question

我在ASP.net MVC项目中使用Rotativa。我使用ViewAsPDF作为返回类型。问题是在本地环境中一切运行顺利，css风格正确地应用于PDF，但是当我在prod服务器上部署我的应用程序并尝试获取PDF文件时，服务器仅在约5分钟后才返回它而没有应用CSS样式。如果我直接将样式赋予属性<td style="..."> 有用。我在哪里可以找到问题，以及如何解决？

谢谢！

更新如果删除CSS样式表的链接，它的工作速度会快得多：

更新如果我在任何网站页面上手动运行wkhtmltopdf.exe，我会得到：

%computername% | D:\Projects\myapp\trunk\WebSite\Rotativa>wkhtmltopdf http://myappp.com pdf.pfd
Loading pages (1/6)
Error: Failed loading page http://finishgenius.tizbi.com (sometimes it will work just to ignore this error with --load-error-handling ignore)

更新如果我将方法ViewAsPdf更改为ActionAsPDF我收到错误：

终于找到问题的根源所在。我试图从服务器的浏览器访问我的网站，我发现服务器看不到自己。我用适当的IP地址更新了hosts.txt文件，这解决了我的问题。希望这会对某人有所帮助！谢谢！

Answer 2

当您的网站使用Windows身份验证时，可能会发生另一种可能的原因。

您需要在web.config中授予对CSS文件的访问权限，如下所示：

predArbreDecision=predict(ad.apprentissage,newdata=test,type="class")
