如何在运行时重新加载 asp.net 核心标识选项

Question

我们实施了一个管理系统，允许管理员更改密码复杂性规则。启动时，这些选项将应用于services.AddIdentity<User, Role>(setupAction)中的核心标识 asp.net。因此，每当我们重新启动服务器应用程序时，都会应用这些选项。我们如何在运行时强制重新加载这些设置(无需重新启动应用程序(

Answer 1

不要在"启动"中设置选项。而是添加自定义密码验证器：

services.AddIdentity<ApplicationUser, IdentityRole>()
    .AddEntityFrameworkStores<ApplicationDbContext>()
    .AddDefaultTokenProviders()
    .AddPasswordValidator<UsernameAsPasswordValidator<ApplicationUser>>();

从

服务中删除密码选项。AddIdentity<User，>(setupAction(

然后使用 services.Configure<IdentityOptions>(options =>{ options.Password.RequireDigit = 3;....});添加密码选项

从数据库更改标识选项的示例

  private readonly UnitOfWork _unitOfWork;
    private readonly IdentityOptions options;
    private readonly DataProtectionTokenProviderOptions _tokenProviderOptions;
    private readonly EmailConfirmationTokenProviderOptions _emailTokenProrvider;
    public UpdateHandler(UnitOfWork unitOfWork, IOptions<IdentityOptions> options, 
        IOptions<DataProtectionTokenProviderOptions> tokenProviderOptions,
        IOptions<EmailConfirmationTokenProviderOptions> emailTokenProrvider)
    {
        _unitOfWork = unitOfWork;
        _emailTokenProrvider = emailTokenProrvider.Value;
        _tokenProviderOptions = tokenProviderOptions.Value;
        this.options = options.Value;
    }

    public async Task<ResultResponse> Handle(UpdatePolicy request, CancellationToken cancellationToken)
    {
        if (_unitOfWork.IdentitySettingPolicy.SettingExist(request.IdentitySetting.Id))
        {
            var setting = request.IdentitySetting;
            _unitOfWork.IdentitySettingPolicy.UpdateSetting(request.IdentitySetting);
            _unitOfWork.Save();
            options.Password.RequireDigit = setting.RequireDigit;
            options.Password.RequiredLength = setting.RequiredLength;
            options.Password.RequireNonAlphanumeric = setting.RequireNonAlphanumeric;
            options.Password.RequireUppercase = setting.RequireUppercase;
            options.Password.RequireLowercase = setting.RequireLowercase;
            options.Password.RequiredUniqueChars = setting.RequiredUniqueChars;
            // Lockout settings
            options.Lockout.DefaultLockoutTimeSpan = TimeSpan.FromMinutes(setting.DefaultLockoutTimeSpanMinute);
            options.Lockout.MaxFailedAccessAttempts = setting.MaxFailedAccessAttempts;
            options.Lockout.AllowedForNewUsers = true;
            // User settings
            options.User.RequireUniqueEmail = false;
            // SignIn settings
            //options.SignIn.RequireConfirmedEmail = false;
            // options.SignIn.RequireConfirmedPhoneNumber = false;
            options.SignIn.RequireConfirmedAccount = setting.RequireConfirmedAccount;
            //Email token provider
            options.Tokens.EmailConfirmationTokenProvider = "EmailConFirmation";
            _tokenProviderOptions.TokenLifespan = TimeSpan.FromHours(setting.TokenLifespanHour);
            _emailTokenProrvider.TokenLifespan = TimeSpan.FromHours(setting.TokenLifespanHour);
            return new ResultResponse(true, "Policy Updated", request.IdentitySetting);
        }
        throw new Exception(ErrorRes.EntityNotExist);

    }
