  hi

  You can give it a try. I think it will be works.

  Like your example website, it automatically jumps to the login page.

  The demo website is angular. You are using Blazor Server.

  I am using blazor server, and I found that your example is not enough. The effect I want is that when accessing the system homepage, if there is no login, it will automatically jump to the login page. There is no need to manually click login and then jump to the login page.

  You can inject the ICurrentUser service and use IsAuthenticated to check the user whatever is logged.

  hi pvaz

  You can call ChallengeAsync in yourOnGetAsync method of IndexModel for MVC tiered application.

  public class IndexModel : MyProjectNamePageModel
  {
      public async Task OnGetAsync()
      {
          if (!CurrentUser.IsAuthenticated)
          {
              await HttpContext.ChallengeAsync("oidc");
          }
      }
  
      public async Task OnPostLoginAsync()
      {
          await HttpContext.ChallengeAsync("oidc");
      }
  }

  Hi Maliming,

  thank you for your quick reply.

  Perhaps my question I was not clear. When the user is not authenticated to redirect to /Account/Login.

  Using your example I get:

  "An unhandled exception occurred while processing the request. InvalidOperationException: No authentication handler is registered for the scheme 'oidc'. The registered schemes are: idsrv, idsrv.external, Abp.ConfirmUser, Identity.Application, Identity.External, Identity.TwoFactorRememberMe, Identity.TwoFactorUserId, Bearer, Google, Microsoft, Twitter. Did you forget to call AddAuthentication().AddSomeAuthHandler? Microsoft.AspNetCore.Authentication.AuthenticationService.ChallengeAsync(HttpContext context, string scheme, AuthenticationProperties properties)"

  Thx

  hi pvaz

  I think you can redirect user to any page.

  if (!CurrentUser.IsAuthenticated)
  {
      //redirect to /Account/Login
  }

  Hi,

  solved this way using your advice:

  var redirectUrl = UriHelper.BuildAbsolute(HttpContext.Request.Scheme, HttpContext.Request.Host, "/Account/Login"); await HttpContext.ChallengeAsync(new AuthenticationProperties { RedirectUri = redirectUrl });

  return;`
