Rotativa 1.6.1给出了“未经测试的WindowsVersion6.2检测！”作为异常的消息

Question

我有一个the服务器运行同一站点的多个版本。现场运作良好。测试站点抛出“未经测试的WindowsVersion6.2检测到！”当我试图生成PDF时出错。将Rotativa文件夹从工作现场复制到测试站点无助于此。升级到较新版本的Rotativa会给我带来其他问题，这些问题现在还没有被列入解决之列(我们正在考虑离开它)。

我觉得这与代码无关，但与权限有关，但我找不到任何方法让它工作。为了完整起见，下面是堆栈：

[Exception: Qt: Untested Windows version 6.2 detected!
Error: Failed loading page http://test.mysite.com/Home/PrintBackorderView (sometimes it will work just to ignore this error with --load-error-handling ignore)

Answer 1

Rotativa是旧的Nokia浏览器的包装器，它加载您创建的页面并将其呈现为PDF。显然，这个软件有时需要一些帮助来解析它需要解析的内容的地址，所以我将域添加到主机文件中。
