asp.net - 在 MapSpaFallbackRoute 中使用命名路由

Question

我在 ASP.NET Core SPA 中使用命名路由，如下所示:

[HttpGet("", Name = HomeControllerRouteName.GetIndex)]
public IActionResult Index() => this.View();

在我的 Startup.cs我使用 MapSpaFallbackRoute回退到单页应用程序以显示 404 错误页面的方法。它目前使用 Controller 和 Action 名称来确定回退路线，如下所示:

application.UseMvc(
    routes =>
    {
        routes.MapSpaFallbackRoute(
            name: "spa-fallback",
            defaults: new { controller = "Home", action = "Index" });
    });

我想在我的 Startup.cs 中使用命名路由为了一致性。如何做到这一点？

有条件地映射 SPA 回退路线

// API Routes
       app.UseMvc(routes =>
        {
            routes.MapRoute(
                name: "default",
                template: "{controller=Home}/{action=Index}/{id?}");
        });

        // This route will never be mapped when route starts with api
        app.MapWhen(x => !x.Request.Path.Value.StartsWith("/api"), builder =>
        {
            builder.UseMvc(routes =>
            {
                routes.MapSpaFallbackRoute(
                    name: "spa-fallback",
                    defaults: new { controller = "Home", action = "Index" });
            });
        });
