在 Y 次无效尝试和 userManager.IsLockedOutAsync 为 false 后锁定 ASP.NET 登录用户 X 分钟

Question

我正在研究 asp.net web api 项目并尝试实现在 Y 次无效尝试后将用户登录锁定 X 分钟的功能。

我在身份配置中设置了这个

        // Enable Lock outs
        manager.MaxFailedAccessAttemptsBeforeLockout = 1;
        manager.DefaultAccountLockoutTimeSpan = new TimeSpan(0, 5, 0);
        manager.UserLockoutEnabledByDefault = true;

在IdentityConfig.cs中

public static ApplicationUserManager Create(IdentityFactoryOptions<ApplicationUserManager> options, IOwinContext context)
    {
        var manager = new ApplicationUserManager(new UserStore<ApplicationUser>(context.Get<ApplicationDbContext>()));
        // Configure validation logic for usernames
        manager.UserValidator = new UserValidator<ApplicationUser>(manager)
        {
            AllowOnlyAlphanumericUserNames = false,
            RequireUniqueEmail = true,
             
        };
        // Enable Lock outs

        manager.MaxFailedAccessAttemptsBeforeLockout = 1;
        manager.DefaultAccountLockoutTimeSpan = new TimeSpan(0, 5, 0);
        manager.UserLockoutEnabledByDefault = true;
        // Configure validation logic for passwords
        manager.PasswordValidator = new PasswordValidator
        {
            RequiredLength = 6,
            RequireNonLetterOrDigit = true,
            RequireDigit = true,
            RequireLowercase = true,
            RequireUppercase = true,
        };

        manager.EmailService = new EmailServiceCustom();
        int Token = 24;
        if (ConfigurationManager.AppSettings["TokenLifespan"] != null
         )
        {
            Token = Convert.ToInt32(ConfigurationManager.AppSettings["TokenLifespan"]);
        }

        var dataProtectionProvider = options.DataProtectionProvider;
        if (dataProtectionProvider != null)
        {
            manager.UserTokenProvider = new DataProtectorTokenProvider<ApplicationUser>(dataProtectionProvider.Create("ASP.NET Identity"))
            {
                TokenLifespan = System.TimeSpan.FromHours(Token)
            };
        }
        return manager;
    }

并在OAuthProvider.cs Class

   public override async Task GrantResourceOwnerCredentials(OAuthGrantResourceOwnerCredentialsContext context)
        {
            //context.OwinContext.Response.Headers.Add("Access-Control-Allow-Origin", new[] { "*" });
            var userManager = context.OwinContext.GetUserManager<ApplicationUserManager>();


            var user = await userManager.FindByNameAsync(context.UserName).ConfigureAwait(false);

            //var user= await context.OwinContext.GetUserManager<ApplicationUserManager>()
            //    .FindAsync(context.UserName, context.Password).ConfigureAwait(false);
            if (user == null)
            {
                context.SetError("invalid_grant", "The user name is incorrect.");
                return;
            }
            
            if (await userManager.IsLockedOutAsync(user.Id))
            {
                context.SetError("locked_out", "User is locked out");
                return;
            }

            if (!await userManager.IsEmailConfirmedAsync(user.Id))
            {
                context.SetError("invalid_grant", "You need to confirm your email.");
                return;
            }

            var check = await userManager.CheckPasswordAsync(user, context.Password);

            if (!check)
            {
                await userManager.AccessFailedAsync(user.Id);
                context.SetError("invalid_grant", "The password is incorrect."); //wrong password
                return;
            }
            ClaimsIdentity oAuthIdentity = await (await userManager.FindAsync(context.UserName, context.Password).ConfigureAwait(false)).GenerateUserIdentityAsync(userManager, "JWT").ConfigureAwait(false);
            
            var userForCheck = this.userService.GetUserById((await userManager.FindAsync(context.UserName, context.Password).ConfigureAwait(false)).Id);
            AuthenticationTicket ticket;

            if ((oAuthIdentity.IsAuthenticated && userForCheck == null) ||
                oAuthIdentity.IsAuthenticated && userForCheck.status)
            {
                var claims = new List<Claim>();

                var roles = await userManager.GetRolesAsync((await userManager.FindAsync(context.UserName, context.Password).ConfigureAwait(false)).Id).ConfigureAwait(false);
                claims.AddRange(roles.Select(role => new Claim("role", role)));

                claims.Add(new Claim("unique_name", (await userManager.FindAsync(context.UserName, context.Password).ConfigureAwait(false)).UserName));
                claims.Add(new Claim("email", (await userManager.FindAsync(context.UserName, context.Password).ConfigureAwait(false)).Email));

                oAuthIdentity.AddClaims(claims);
                ticket = new AuthenticationTicket(oAuthIdentity, null);
                context.Validated(ticket);
            }
        }

但是user.LockoutEnabled是 false 并且userManager.IsLockedOutAsync(user.Id)即使在无效尝试之后也返回 false 。 我在这里做错了什么？

我得到了这个帮助，但仍然是同样的问题

Answer 1

如果有人偶然发现这个问题：

如果您在实施锁定功能之前创建了用户，则UserLockoutEnabledByDefault将被忽略。 这是因为默认值仅在值 ( UserLockOut ) 为 null 时适用。 但是，此属性设置为 false。

因此，您需要进行一次性更改以将锁定设置为 true（仅适用于现有用户）。 eg await userManager.SetLockoutEnabledAsync(user.Id, true);
