  How to catch maintain session UserId Asp.Net.DefaultAuthenticationTypes

  Jan 15, 2019 07:43 AM|Enzyme|LINK

  I use Asp.Net Identity in Visual Studio 2015 framework 4.5.1, I want to catch and maintain user's ID as Session [UserId] when user login.

  this is my Login code

   protected void LogIn(object sender, EventArgs e)
          {
              if (IsValid)
              {
                  // Validate the user password
                  var manager = Context.GetOwinContext().GetUserManager<ApplicationUserManager>();
                  var signinManager = Context.GetOwinContext().GetUserManager<ApplicationSignInManager>();
  
                  // This doen't count login failures towards account lockout
                  // To enable password failures to trigger lockout, change to shouldLockout: true
                  var result = signinManager.PasswordSignIn(Email.Text, Password.Text, RememberMe.Checked, shouldLockout: false);
  
                  switch (result)
                  {
                      case SignInStatus.Success:
                          IdentityHelper.RedirectToReturnUrl("/userpage.aspx", Response);
                          break;
                      case SignInStatus.LockedOut:
                          Response.Redirect("/Account/Lockout");
                          break;
                      case SignInStatus.RequiresVerification:
                          Response.Redirect(String.Format("/Account/TwoFactorAuthenticationSignIn?ReturnUrl={0}&RememberMe={1}", 
                                                          Request.QueryString["ReturnUrl"],
                                                          RememberMe.Checked),
                                            true);
                          break;
                      case SignInStatus.Failure:
                      default:
                          FailureText.Text = "Invalid login attempt";
                          ErrorMessage.Visible = true;
                          break;
                  }
                  
              }
          }
      }

  This is my AplicationUser class in Identity.Model

   public class ApplicationUser : IdentityUser
      {
          public ClaimsIdentity GenerateUserIdentity(ApplicationUserManager manager)
          {
              // Note the authenticationType must match the one defined in CookieAuthenticationOptions.AuthenticationType
              var userIdentity = manager.CreateIdentity(this, DefaultAuthenticationTypes.ApplicationCookie);
              // Add custom user claims here
              userIdentity.AddClaim(new Claim("UserId", this.Id));
  
              return userIdentity;
          }
  
          public Task<ClaimsIdentity> GenerateUserIdentityAsync(ApplicationUserManager manager)
          {
              return Task.FromResult(GenerateUserIdentity(manager));
          }
      }

  This is My Startup Auth

   public void ConfigureAuth(IAppBuilder app)
          {
              // Configure the db context, user manager and signin manager to use a single instance per request
              app.CreatePerOwinContext(ApplicationDbContext.Create);
              app.CreatePerOwinContext<ApplicationUserManager>(ApplicationUserManager.Create);
              app.CreatePerOwinContext<ApplicationSignInManager>(ApplicationSignInManager.Create);
  
              // Enable the application to use a cookie to store information for the signed in user
              // and to use a cookie to temporarily store information about a user logging in with a third party login provider
              // Configure the sign in cookie
  
              app.UseCookieAuthentication(new CookieAuthenticationOptions
              {
                  AuthenticationType = DefaultAuthenticationTypes.ApplicationCookie,
                  LoginPath = new PathString("/Account/Login"),
                  Provider = new CookieAuthenticationProvider
                  {
                      OnValidateIdentity = SecurityStampValidator.OnValidateIdentity<ApplicationUserManager, ApplicationUser>(
                          validateInterval: TimeSpan.FromMinutes(30),
                          regenerateIdentity: (manager, user) => user.GenerateUserIdentityAsync(manager))
                  }
              });

  So, how do catch the userID and store it for other uses

  Hi Enzyme,

  If the user has logged in , you could get the username through HttpContext.Current.User.

  IPrincipal principle=   HttpContext.Current.User;
               IIdentity  identity =  principle.Identity;
                string name =  identity.Name;

  Then you could get the IdentityUser  by UserManager according to the username.

  Also,it seems you could get the email of the user. You could get the user through UserManger's findXXX method.

  UserManager.FindByEmail

  Finally , you could save it in session.

  Best regards,

  IPrincipal principle=   HttpContext.Current.User;
               IIdentity  identity =  principle.Identity;
                string name =  identity.Name;

  Ackerly Xu, thank you for your response, but how do I place this code on my page using my codes in the above page of this post?
  Note, I am still new to this.

  Hi Enzyme,

  After the user has logged in successfully , you could find the user using UserManager and save the found user in Session.

   case SignInStatus.Success:
                          // get the user using UserManager
                           ApplicationUser  user = manager.FindByEmail(the user's email);
                           string id = user.Id;
                          Session["user_id"] = id;
                          IdentityHelper.RedirectToReturnUrl("/userpage.aspx", Response);
  

  Best regards,

  Thanks Ackerly Xu, I took another approach to resolve the issue. I used the code below

  string userId = User.Identity.GetUserId();
  var user = (new ApplicationDbContext()).Users.FirstOrDefault(s => s.Id == userId);
