英文:
.NET 7 map file pattern to static file serving
问题
目前我有普通的方法：
app.UseStaticFiles(new StaticFileOptions{FileProvider = new PhysicalFileProvider(storageDirectory),RequestPath = "/"});
但我想要更多类似于这样的东西：
app.UseStaticFiles(new StaticFileOptions{FileProvider = new PhysicalFileProvider(storageDirectory),RequestPath = "/[a-b0-9\\-]+/.+"});
是否有可能以某种方式实现这个需求？

我可以看到在源代码中，路径是通过 StartsWithSegments 进行检查的：
https://github.com/dotnet/aspnetcore/blob/main/src/Middleware/StaticFiles/src/Helpers.cs
似乎我需要编写一个自定义的中间件？
英文:
I there a way to serve static files with .NET 7 only for certain file patterns?
Currently I have the plain old:
app.UseStaticFiles(new StaticFileOptions{FileProvider = new PhysicalFileProvider(storageDirectory),RequestPath = "/",});
But I'm looking for something more link
app.UseStaticFiles(new StaticFileOptions{FileProvider = new PhysicalFileProvider(storageDirectory),RequestPath = "/[a-b0-9\-]+/.+"});
Is that possible somehow?
[Update 1]
I can see in the source that the path is checked with StartsWithSegments:
https://github.com/dotnet/aspnetcore/blob/main/src/Middleware/StaticFiles/src/Helpers.cs
internal static bool TryMatchPath(HttpContext context, PathString matchUrl, bool forDirectory, out PathString subpath){var path = context.Request.Path;if (forDirectory && !PathEndsInSlash(path)){path += new PathString("/");}if (path.StartsWithSegments(matchUrl, out subpath)){return true;}return false;}
Seems like I need to write a custom middleware?

根据文档：
> RequestPath
> 映射到静态资源的相对请求路径。默认为站点根目录 '/'。
即它只允许指定静态资源所在的文件夹。
您可以尝试的一个选项是通过 UseWhen 分支中间件管道 的选项：
app.UseWhen(ctx => Regex.IsMatch(ctx.Request.Path.Value ?? "", ""), appBuilder =>appBuilder.UseStaticFiles(new StaticFileOptions{FileProvider = new PhysicalFileProvider(storageDirectory),}));
英文:
As per docs:
> RequestPath
> The relative request path that maps to static resources. This defaults to the site root '/'.
i.e. it will allow only to specify the folder where static resources are located.
One option you can try is the option to branch the middleware pipeline via UseWhen:
app.UseWhen(ctx => Regex.IsMatch(ctx.Request.Path.Value ?? "", ""), appBuilder =>appBuilder.UseStaticFiles(new StaticFileOptions{FileProvider = new PhysicalFileProvider(storageDirectory),}));
