asp.net core 3 routing - asp.net-core

Question

In my Asp.net core 3 project I am using some controler to access from js code to do some stuff and also using Razor pages at the same time.
at the configure service section :
services.AddControllersWithViews();
services.AddRazorPages();
I added both RazorPages and MVC controller with view.
And at then configure section
app.UseRouting();
app.UseEndpoints(endpoints =>
{
endpoints.MapRazorPages();
endpoints.MapControllerRoute(
name: "default",
pattern: "{controller=Home}/{action=Index}/{id?}");
});
Added above codes.
When I try to access to controller I am getting 404. I also tried to add just services.AddControllers();
need help please.
Edit : controller code
public class DashboardsController : BaseController, IDashboardsController
{
[HttpGet]
public async Task<JsonResult> GetAssetCategorySummaryAsync(){
-------
}
}

Answer 1

Your url should be localhost:9011/Dashboards/GetAssetCategorySummary.
You could modify the Startup.cs like below to allow using the whole action name:
public void ConfigureServices(IServiceCollection services)
{
services.AddMvc(options =>
{
options.SuppressAsyncSuffixInActionNames = false;
});
services.AddControllersWithViews();
services.AddRazorPages();
}
It is a known issue on github,you could refer to here.

I can recommend my solution.
In Startup
app.UseHttpsRedirection();
app.UseRouting();
app.UseAuthorization();
app.UseEndpoints(endpoints =>
{
endpoints.MapControllers();
});
Create your CUSTOM base controller like that.
[Route("api/[controller]/[action]/{id?}")]
[ApiController]
public class CustomBaseController : ControllerBase
{
}
And use CustomBaseController
public class TestController : CustomBaseController
{
public IActionResult Test()
{
return Ok($"Test {DateTime.UtcNow}");
}
}
Rout` api/Test/test
