html - Rotativa 在服务器上的 css 样式有问题

Question

我正在使用 Rotativa在我的 ASP.net MVC 元素中。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 样式正确应用于 PDF，但是当我在产品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 ~ 5 分钟后返回它而没有应用 CSS 样式.如果我直接将样式赋予属性 <td style="..."> 有用。在哪里可以找到问题以及如何解决？

谢谢!

更新: 如果我删除指向 CSS 样式表的链接，它会工作得更快:

更新: 如果我在我的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了。我试图从服务器的浏览器访问我的网站，但我发现服务器看不到自己。我用正确的 IP 地址更新了 hosts.txt 文件，这解决了我的问题。希望这会帮助别人!谢谢!
