Azure App Service .msg文件与其余文件一起保存在wwwroot中，但显示找不到文件吗？

对Web应用程序文件的访问受基础Web服务器限制，因此不是由于扩展名引起的。您可以通过在应用程序根目录中创建一个web.config文件并使用本指南中的内容来启用对目录的匿名访问：

<?xml version="1.0" encoding="UTF-8"?>
<configuration>
   <location path="{your-temp-directory}" allowOverride="false">
      <system.webServer>
         <directoryBrowse enabled="false"/>
         <defaultDocument>
            <files>
               <!-- When requesting a file listing, don't serve up the default 
               index.html file if it exists. -->
               <clear />
            </files>
         </defaultDocument>
         <security>
            <authorization>
               <!-- Allow all users access to the Public folder -->
               <remove users="*" roles="" verbs="" />
               <add accessType="Allow" users="*" roles="" />
            </authorization>
            <!-- Unblock all sourcecode related extensions (.cs, .aspx, .mdf)
             and files/folders (web.config, \bin) -->
            <requestFiltering>
               <hiddenSegments>
                  <clear />
               </hiddenSegments>
               <fileExtensions>
                  <clear />
               </fileExtensions>
            </requestFiltering>
         </security>
         <!-- Remove all ASP.NET file extension associations.
           Only include this if you have the ASP.NET feature installed, 
           otherwise this produces an Invalid configuration error. -->
         <handlers>
            <clear />
            <add name="StaticFile" path="*" verb="*" modules="StaticFileModule,DefaultDocumentModule,DirectoryListingModule" resourceType="Either" requireAccess="Read" />
         </handlers>
         <!-- Map all extensions to the same MIME type, so all files can be
           downloaded. -->
         <staticContent>
            <clear />
            <mimeMap fileExtension="*" mimeType="application/octet-stream" />
         </staticContent>
      </system.webServer>
   </location>
</configuration>

<directoryBrowse/>由于您可能不想允许目录内容列出，因此我从指南中找到的标记中更改了标记。自然，{您的临时目录}相对于web.config文件。重新启动您的Web应用程序，您应该一切顺利。
