I need some data to store in session which is reuse after logined.
I had override CreateAsync(User user) method in UserClaimsPrincipalFactory.cs. Look it

public override async Task CreateAsync(User user)

{
var claim = await base.CreateAsync(user);
        var resObj = (from res in _reservationRepository.GetAll()
                      join gs in _guestRepository.GetAll() on res.GuestKey equals gs.Id
                      join r in _roomRepository.GetAll() on res.RoomKey equals r.Id
                      where (res.Status == 1 || res.Status == 2) && (gs.EMail == user.EmailAddress || gs.LastName == user.UserName)
                      select new 
                      {
                          DocNo = res.DocNo,
                          ReservationKey = res.Id,
                          GuestKey = gs.Id
                      }).FirstOrDefault();
        if (resObj != null)
        {
            claim.Identities.First().AddClaim(new Claim("Application_DOCNO", resObj.DocNo));
        }

        return claim;// it is ok. Docno value have in claims.
    }

Then I created MyAppSession Class folowing :

    public class MyAppSession : ClaimsAbpSession, ITransientDependency,IMyAppSession
{
    public MyAppSession(
    IPrincipalAccessor principalAccessor,
    IMultiTenancyConfig multiTenancy,
    ITenantResolver tenantResolver,
    IAmbientScopeProvider<SessionOverride> sessionOverrideScopeProvider) :
    base(principalAccessor, multiTenancy, tenantResolver, sessionOverrideScopeProvider)
    {
    }
    public string DOCNO
    {
        get
        {
            var userDocClaim = PrincipalAccessor.Principal?.Claims.FirstOrDefault(c => c.Type == "Application_DOCNO");
            if (userDocClaim == null || string.IsNullOrEmpty(userDocClaim?.Value))
            {
                return null;
            }

            return userDocClaim.Value;
        }

    }

This is IMyAppSession Interface

public interface IMyAppSession
{
string DOCNO { get; }
}

This is session value retrive class

public class TokenAuthController : BEZNgCoreControllerBase
{
private readonly IMyAppSession \_p;
public TokenAuthController(IMyAppSession p)
{
\_p = p;
}
    public string GetSession()
    {
        return _p.DOCNO;// Here value is null. Why?
    }
}

Is there anything need to change? Please help me.

Hi billyteng,
You need to replace the default UserClaimsPrincipalFactory in the IoC container.
Module code:

public class YourApplicationModule : AbpModule
{
    public override void PreInitialize()
    {
        IocManager.IocContainer.Register(
            Component
                .For<IUserClaimsPrincipalFactory<User>, CustomClaimFactory>()
                .LifestyleTransient()
                .IsDefault());
    }
}

Custom session code:

public class CustomClaimFactory : AbpUserClaimsPrincipalFactory<User, Role>
{
    public CustomClaimFactory(AbpUserManager<Role, User> userManager,
        AbpRoleManager<Role, User> roleManager,
        IOptions<IdentityOptions> optionsAccessor) : base(userManager,
        roleManager,
        optionsAccessor)
    {
    }

    public override async Task<ClaimsPrincipal> CreateAsync(User user)
    {
        var claim = await base.CreateAsync(user);

        claim.Identities.First()
            .AddClaim(new Claim("Custom", "Hello World"));

        return claim;
    }
}

public interface ICustomAppSession
{
    string Custom { get; }
}

public class CustomAppSession : ClaimsAbpSession,
    ITransientDependency,
    ICustomAppSession
{
    public CustomAppSession(IPrincipalAccessor principalAccessor,
        IMultiTenancyConfig multiTenancy,
        ITenantResolver tenantResolver,
        IAmbientScopeProvider<SessionOverride> sessionOverrideScopeProvider) : base(principalAccessor,
        multiTenancy,
        tenantResolver,
        sessionOverrideScopeProvider)
    {
    }

    public string Custom
    {
        get
        {
            var userDocClaim = PrincipalAccessor.Principal?.Claims.FirstOrDefault(c => c.Type == "Custom");
            if (userDocClaim == null || string.IsNullOrEmpty(userDocClaim?.Value))
            {
                return null;
            }

            return userDocClaim.Value;
        }
    }
}

public class TestAppService : QADemoDemoAppServiceBase
{
    private readonly IUserClaimsPrincipalFactory<User> _claimsPrincipalFactory;
    private readonly ICustomAppSession _customAppSession;
    private readonly UserManager _userManager;

    public TestAppService(ICustomAppSession customAppSession,
        IUserClaimsPrincipalFactory<User> claimsPrincipalFactory,
        UserManager userManager)
    {
        _customAppSession = customAppSession;
        _claimsPrincipalFactory = claimsPrincipalFactory;
        _userManager = userManager;
    }

    public async Task<string> GetInfoAsync()
    {
        var user = await _userManager.GetUserByIdAsync(AbpSession.UserId.Value);

        var value = _customAppSession.Custom;
        var claims = await _claimsPrincipalFactory.CreateAsync(user);
        await Task.CompletedTask;

        return "Ok";
    }
}

Hi Zony,
Thanks for your reply. I did your follow. But it's still null value. Not show "Hello World". Look my code.

In Application layer
public class NameNgCoreApplicationModule : AbpModule
{
public override void PreInitialize()
{
//Adding authorization providers
Configuration.Authorization.Providers.Add<AppAuthorizationProvider>();

        //Adding custom AutoMapper configuration
        Configuration.Modules.AbpAutoMapper().Configurators.Add(CustomDtoMapper.CreateMappings);

        //For CustomClaimFactory
        IocManager.IocContainer.Register(
        Component
            .For<IUserClaimsPrincipalFactory<User>, CustomClaimFactory>()
            .LifestyleTransient()
            .IsDefault());
    }

    public override void Initialize()
    {
        IocManager.RegisterAssemblyByConvention(typeof(BEZNgCoreApplicationModule).GetAssembly());
    }
}

I created "CustomClaimFactory" class in NameNgCore.Core project.

public class CustomClaimFactory : AbpUserClaimsPrincipalFactory<User, Role>
{
private readonly IRepository<Guest, Guid> _guestRepository;
private readonly IRepository<Reservation, Guid> _reservationRepository;
private readonly IRepository<Room, Guid> _roomRepository;

    public CustomClaimFactory(AbpUserManager<Role, User> userManager,
    AbpRoleManager<Role, User> roleManager,
    IOptions<IdentityOptions> optionsAccessor,
    IRepository<Guest, Guid> guestRepository,
    IRepository<Reservation, Guid> reservationRepository,
    IRepository<Room, Guid> roomRepository

        ) : base(userManager,
    roleManager,
    optionsAccessor)
    {
        _guestRepository = guestRepository;
        _reservationRepository = reservationRepository;
        _roomRepository = roomRepository;
    }
    public override async Task<ClaimsPrincipal> CreateAsync(User user)
    {
        var claim = await base.CreateAsync(user);

        var resObj = (from res in _reservationRepository.GetAll()
                      join gs in _guestRepository.GetAll() on res.GuestKey equals gs.Id
                      join r in _roomRepository.GetAll() on res.RoomKey equals r.Id
                      where (res.Status == 1 || res.Status == 2) && (gs.EMail == user.EmailAddress || gs.LastName == user.UserName)
                      select new
                      {
                          DocNo = res.DocNo,
                          ReservationKey = res.Id,
                          GuestKey = gs.Id
                      }).FirstOrDefault();
         // resObj has value             
        if (resObj != null)
        {
            claim.Identities.First().AddClaim(new Claim("Application_DOCNO", "Hello World"));
          
        }           

        return claim;
    }
}

public interface IMyAppSession
{
    string DOCNO { get; }      
}

public class MyAppSession : ClaimsAbpSession, ITransientDependency,IMyAppSession
{
public MyAppSession(
IPrincipalAccessor principalAccessor,
IMultiTenancyConfig multiTenancy,
ITenantResolver tenantResolver,
IAmbientScopeProvider<SessionOverride> sessionOverrideScopeProvider) :
base(principalAccessor, multiTenancy, tenantResolver, sessionOverrideScopeProvider)
{
}
public string DOCNO
{
get
{
var userDocClaim = PrincipalAccessor.Principal?.Claims.FirstOrDefault(c => c.Type == "Application_DOCNO");
if (userDocClaim == null || string.IsNullOrEmpty(userDocClaim?.Value))
{
return null;
}

            return userDocClaim.Value;                
        }

    }
 }
 
 This is TokenAuthController in NameNgCore.Web.Core project
 which  call store values
 
  public class TokenAuthController : NameNgCoreControllerBase
{
private readonly IUserClaimsPrincipalFactory<User> _iclaimsPrincipalFactory;
private readonly IMyAppSession _p;
public TokenAuthController(IMyAppSession p,
        IUserClaimsPrincipalFactory<User> iclaimsPrincipalFactory
)
{
 _p = p;
        _iclaimsPrincipalFactory = iclaimsPrincipalFactory;
}

 [HttpPost]
    public async Task<AuthenticateResultModel> Authenticate([FromBody] AuthenticateModel model)
    {
        your code ...ok....then.......
        var loginResult = await GetLoginResultAsync(
            model.UserNameOrEmailAddress,
            model.Password,
            GetTenancyNameOrNull()
        );
        ..........
         var refreshToken = CreateRefreshToken(await CreateJwtClaims(loginResult.Identity, loginResult.User,
            tokenType: TokenType.RefreshToken));
        var accessToken = CreateAccessToken(await CreateJwtClaims(loginResult.Identity, loginResult.User,
            refreshTokenKey: refreshToken.key));
            
        var claims = await _iclaimsPrincipalFactory.CreateAsync(loginResult.User);

        var d =_p.DOCNO ; // here value is null. Actually it must show "Hello World" 
        
        return new AuthenticateResultModel
        {
            AccessToken = accessToken,
            ExpireInSeconds = (int)_configuration.AccessTokenExpiration.TotalSeconds,
            RefreshToken = refreshToken.token,
            RefreshTokenExpireInSeconds = (int)_configuration.RefreshTokenExpiration.TotalSeconds,
            EncryptedAccessToken = GetEncryptedAccessToken(accessToken),
            TwoFactorRememberClientToken = twoFactorRememberClientToken,
            UserId = loginResult.User.Id,
            ReturnUrl = returnUrl
        };
    }
}

please help me..Is there anything path?

Hi billyteng,
It seems that there is no problem. Can you send the sample project to info@aspnetzero.com? Please include Question-9982 in the email.

It seems that the value of resObj may be Null. I suggest you check whether this code is the expected situation.

         if (resObj != null)
         {
             claim.Identities.First().AddClaim(new Claim("Application_DOCNO", "Hello World"));
         }

Hi @billyteng
You are trying to get session value before it is initialized. Session value is null when use try to login, you can check

var abpUser = AbpSession.ToUserIdentifier();

It will also be null.
Try to get it where session is set. For example in the logout of the same controller
.

And implementing custom session is very simple. No need to make it complex. Check that: https://aspnetboilerplate.com/Pages/Documents/Articles\How-To\add-custom-session-field-aspnet-core

Here are my changes for your implementation.
