c# - 在 ASP.NET Core for SPA 中确定基于路由或域的静态文件

Question

是否可以根据 ASP.NET Core 2 / 3 + 中的路由返回不同的静态文件？

例如：

app.domain.comindex.html会为公共 SPA渲染一些（ReactJS / VueJS）

admin.domain.comindex.html会为私人认证的 SPA (Angular)渲染一些其他的

www.domain.comindex.html将为公共登录页面呈现三分之一

我在文档中找不到如何https://docs.microsoft.com/en-us/aspnet/core/fundamentals/static-files?view=aspnetcore-3.0

您可以随时尝试自定义文件提供程序：

public class Startup
{
    public void ConfigureServices(IServiceCollection services)
    {
        services.AddOptions<StaticFileOptions>()
            .Configure<IHttpContextAccessor, IWebHostEnvironment>(
                delegate(StaticFileOptions options, IHttpContextAccessor httpContext, IWebHostEnvironment env)
                {
                    options.FileProvider = new ClientAppFileProvider (httpContext, env);
                }
            );

    }

    public void Configure(IApplicationBuilder app)
    {
        app.UseStaticFiles();
    }
}

public class ClientAppFileProvider : IFileProvider
{
    private readonly IHttpContextAccessor _httpContextAccessor;
    private readonly IWebHostEnvironment _env;

    public ClientAppFileProvider(IHttpContextAccessor httpContextAccessor, IWebHostEnvironment env)
    {
        _httpContextAccessor = httpContextAccessor;
        _env = env;
    }

    public IDirectoryContents GetDirectoryContents(string subpath)
    {
        return _env.WebRootFileProvider.GetDirectoryContents(subpath); ;
    } // End Function GetDirectoryContents 


    public IFileInfo GetFileInfo(string subpath)
    {
        string host = _httpContextAccessor.HttpContext.Request.Host.Host;
        if (host.Equals("app.domain.com"))
        {
            subpath = Path.Combine("app", subpath);
        }
        else if (host.Equals("admin.domain.com"))
        {
            subpath = Path.Combine("admin", subpath);
        }
        else if (host.Equals("www.domain.com"))
        {
            subpath = Path.Combine("www", subpath);
        }

        // return _env.ContentRootFileProvider.GetFileInfo(subpath);
        return _env.WebRootFileProvider.GetFileInfo(subpath);
    }


    public IChangeToken Watch(string filter)
    {
        return _env.WebRootFileProvider.Watch(filter);
    } // End Function Watch 


}
