  • UI type: Blazor
  • DB provider:MongoDB

I have a microservice backend and WPF as client application. I'm using client proxy for fetching data from backend, my concern is sometimes I'm struggling to find the existing ClientProxies and finding the permissions definition for template services.

  • Are there a list of predefined clientproxies for me to have a CRUD for administration area like roles,users, audit logs
  • Are there a list of predefined constant string variable for policy names? If so what are the right class or property I should call? Is there a list? (I know that you can get policy names from swagger abpappconfiguration)
  • IAuthorizationService is always returning false even if the current logged user is admin
[DependsOn(typeof(AdministrationServiceHttpApiClientModule))]
public class AdministrationServiceWpfModule : AbpModule{
...
}
...
var auth = ServiceCollection.GetRequiredService<IAuthorizationService>();
var result = await  auth.IsGrantedAsync("AbpIdentity.Users");
//result is always false

    What is the client type are you using? Static or dynamic?

    You just need to use the AppServices to CRUD.

    Are there a list of predefined constant string variable for policy names? If so what are the right class or property I should call? Is there a list? (I know that you can get policy names from swagger abpappconfiguration)

    No, They are existing in the XXX.Application.Constract modules.

    IAuthorizationService is always returning false even if the current logged user is admin

    Can you try to depends on the AbpAspNetCoreMvcClientModule?

    Using IPermissionStore is giving me NullPermissionStore

    Using IAuthorizationService gives me no ClaimsPrincipal

    hi

    I realize you don't need to check permissions in WPF, The AppService will check permissions automatically.

    Also no longer need the AbpAspNetCoreMvcClientModule

    You only need to use the app services to call the method.

    In our case we need to check the permission because we are hiding some controls/navigations if the current user is not granted from a specific policy.

    You can use the IAbpApplicationConfigurationAppService and get the ApplicationConfigurationDto

    Permissions and other info will exist in the DTO,
