在 ASP.Net Core 中使用 MiniProfiler的方法

dotnet add package MiniProfiler.AspNetCore.Mvc

 // This method gets called by the runtime. Use this method to add services to the container.
    public void ConfigureServices(IServiceCollection services)
    {
      services.AddControllersWithViews();

      services.AddMiniProfiler(options => options.RouteBasePath = "/profiler");
    }

 public void Configure(IApplicationBuilder app, IWebHostEnvironment env, ILoggerFactory loggerFactory)
    {
      app.UseMiniProfiler();

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