ASP.NET MVC:如何在MVC应用程序中使用静态HTML页面？

app.UseStaticFiles(); // 启用静态文件支持
app.UseRouting();

app.UseEndpoints(endpoints =>
{
    endpoints.MapControllerRoute(
        name: "default",
        pattern: "{controller=Home}/{action=Index}/{id?}");
    endpoints.MapControllerRoute(
        name: "statichtml",
        pattern: "{*url}",
        defaults: new { controller = "Home", action = "StaticHTML" });
});

public IActionResult StaticHTML()
{
    return PhysicalFile(Path.Combine(Directory.GetCurrentDirectory(), "StaticHTML", "index.html"), "text/html");
}
