Question

使用imageresizer diskcache 4.2.5，并且刚开始出现此错误的可能性很高。这是在最近将新代码发布到我们的网站之后。我们并未明确更改与imageresizer相关的任何知识，因此不确定是否与新版本，web.config问题等有关。

我们正在此MVC 5 Web应用程序中使用预编译的视图。

Gist debug file

这已经工作了多年了。看来我们几个月前已将其nuget软件包从3.4.3升级到4.2.5。

直接导航到图像时，不会引发任何错误。对我来说有趣的是，尝试访问该文件的.tmp命名约定。

尝试从Elmah错误日志中检索的图像路径为：C:\inetpub\wwwroot\website\Images\no_image.jpg?maxwidth=420&maxheight=420

Stacktrace：

Answer 1

这意味着该应用没有对该文件夹的写入权限。临时名称用于防止在写入时被提供。

System.UnauthorizedAccessException：拒绝访问路径'C：\ inetpub \ wwwroot \ website \ imagecache \ 0f \ ae1ea.jpg.tmp_4a1f20d7.tmp'
