使用外部身份验证缓存用户配置文件 .NET Core IdentityServer4

Cache user profile with external authentication .NET Core IdentityServer4

整个身份概念的新手,但我进行了几次 Google 搜索,但没有找到我认为合适的回复。

我将 .NET Core 1.0.0 与 EF Core 和 IdentityServer 4 (ID4) 结合使用。 ID4 在单独的服务器上,我在客户端获得的唯一信息是声明。我想访问完整的(扩展的)用户配置文件,最好来自 User.Identity.

那么我该如何设置,以便在 User.Identity 中填充 ApplicationUser 模型上的所有属性,而无需每次都发送数据库请求?我希望在会话结束前将信息存储在缓存中进行身份验证。

我不想做的是在每个控制器中设置查询以获取附加信息。客户端上的所有控制器都将继承自一个基本控制器,这意味着如果有必要,我可以 DI 一些服务。

提前致谢。

客户端

app.UseCookieAuthentication(new CookieAuthenticationOptions
        {
            AuthenticationScheme = "Cookies"
        });

        app.UseOpenIdConnectAuthentication(new OpenIdConnectOptions
        {
            AuthenticationScheme = "oidc",
            SignInScheme = "Cookies",

            Authority = Configuration.GetSection("IdentityServer").GetValue<string>("Authority"),
            RequireHttpsMetadata = false,
            ClientId = "RateAdminApp"
        });

ID4

app.UseIdentity();

app.UseIdentityServer();

services.AddDeveloperIdentityServer()
            .AddOperationalStore(builder => builder.UseSqlServer("Server=localhost;Database=Identities;MultipleActiveResultSets=true;Integrated Security=true", options => options.MigrationsAssembly(typeof(Startup).GetTypeInfo().Assembly.GetName().Name)))
            .AddConfigurationStore(builder => builder.UseSqlServer("Server=localhost;Database=Identities;MultipleActiveResultSets=true;Integrated Security=true", options => options.MigrationsAssembly(typeof(Startup).GetTypeInfo().Assembly.GetName().Name)))
            .AddAspNetIdentity<ApplicationUser>();

应用程序用户模型

public class ApplicationUser : IdentityUser
{
    [Column(TypeName = "varchar(100)")]
    public string FirstName { get; set; }
    [Column(TypeName = "varchar(100)")]
    public string LastName { get; set; }
    [Column(TypeName = "nvarchar(max)")]
    public string ProfilePictureBase64 { get; set; }
}

如果您想转换身份服务器上的声明,对于您的情况(您使用 aspnet 身份)覆盖 UserClaimsPrincipalFactory 是一个解决方案(参见 Store data in cookie with asp.net core identity)。

public class AppClaimsPrincipalFactory : UserClaimsPrincipalFactory<ApplicationUser, IdentityRole>
{
    public AppClaimsPrincipalFactory(
        UserManager<ApplicationUser> userManager,
        RoleManager<IdentityRole> roleManager,
        IOptions<IdentityOptions> optionsAccessor) : base(userManager, roleManager, optionsAccessor)
    {
    }

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

        ((ClaimsIdentity)principal.Identity).AddClaims(new[] {
             new Claim("FirstName", user.FirstName)
        });

        return principal;
    }
}

// register it
services.AddScoped<IUserClaimsPrincipalFactory<ApplicationUser>, AppClaimsPrincipalFactory>();

您也可以使用事件(在客户端应用程序上)向 cookie 添加额外的声明,它会提供声明直到用户注销。

有两个(可能更多)选项:

首先使用OnTicketReceived的openidconnect认证:

    app.UseOpenIdConnectAuthentication(new OpenIdConnectOptions
    {
        AuthenticationScheme = "oidc",
        SignInScheme = "Cookies",

        Authority = Configuration.GetSection("IdentityServer").GetValue<string>("Authority"),
        RequireHttpsMetadata = false,
        ClientId = "RateAdminApp",
        Events = new OpenIdConnectEvents
        {
           OnTicketReceived = e =>
           {
               // get claims from user profile
               // add claims into e.Ticket.Principal
               e.Ticket = new AuthenticationTicket(e.Ticket.Principal, e.Ticket.Properties, e.Ticket.AuthenticationScheme);

               return Task.CompletedTask;
            }
        }
    });

或者使用OnSigningIncookie认证事件

app.UseCookieAuthentication(new CookieAuthenticationOptions
{
     AuthenticationScheme = "Cookies",
     Events = new CookieAuthenticationEvents()
     {
         OnSigningIn = async (context) =>
         {
             ClaimsIdentity identity = (ClaimsIdentity)context.Principal.Identity;
             // get claims from user profile
             // add these claims into identity
         }
     }
});
