无法读取配置文件\\？\d：\home\site\.知名的\web.config

Question

我遇到了一种奇怪的情况:我在Azure上运行的一个ASP.NET核心网络应用程序存在从特定目录服务文件的问题。

具体来说，我试图从路径https://myurl.com/.well-known/acme-challenge/6uVkXzXxHHkm1d6cQiUqI07lrYspInk7i9WCKKl-RlQ提供一个文件，我注意到这是一个稍微不寻常的url，因为文件路径不包含文件扩展名，目录以(.)开头。这是我无法控制的要求。

不幸的是，虽然我可以在几乎所有的应用程序服务实例中成功地完成这个任务，但我有一个应用程序服务实例失败了，但有以下错误：

无法访问请求的页，因为该页的相关配置数据无效。配置错误无法读取配置文件\？\d：\home\ file .众所周知的\web.config

我的web.config看起来是这样的：

基于错误，它看起来像是出于某种原因，ASP.NET正在我的www.root目录中寻找一个web.config文件。有人能为我做错了什么提供指导吗？

Answer 1

我几乎一发问题就能找到答案。

对于任何遇到这个问题的人来说，问题在于，不知何故，我将虚拟目录映射到此应用程序的路径中。

一旦我去掉了这个，一切都如期而至。
