我有一个 ASP.NET MVC 5 应用程序。它有一个简单的表单,当用户提交它时,表单存储在缓存中,然后调用另一个控制器操作,该操作将模型作为 PDF 视图返回。
我不需要在本地保存它,只是为了在浏览器中显示它,以便用户可以下载它。
也不需要数据库,这就是我将模型存储在缓存中的原因。
在本地,在 Visual Studio 2013 上,它运行良好。但是当我将它发布到 IIS 7 时,我得到一个Unhandled Execution Error
. 这是我返回的堆栈跟踪:
Unhandled Execution Error

我第一次使用ActionAsPDF()
,但现在我也尝试使用return new ViewAsPDF()
. 两者都给出相同的错误和堆栈跟踪。这是否与权限有关?
