Question

整个身份概念的新手，但我有几次谷歌搜索，但没有找到我觉得合适的回复。

我正在使用带有EF Core和IdentityServer 4（ID4）的.NET Core 1.0.0。 ID4位于单独的服务器上，我在客户端获得的唯一信息是声明。我想访问完整（扩展）用户配置文件，最好是User.Identity。

那么如何设置以便User.Identity填充ApplicationUser模型上的所有属性而不必每次都发送数据库请求？我希望在会话结束之前将信息存储在缓存中，直到会话结束。

我不想做的是在每个控制器中设置查询以获取其他信息。客户端上的所有控制器都将继承自基本控制器，这意味着如果必要，我可以使用DI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>();

ApplicationUser Model

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; }
}

如果要在身份服务器上转换声明，对于您的情况（使用aspnet身份），覆盖UserClaimsPrincipalFactory是一种解决方案（请参阅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>();

此外，您可以使用事件（在客户端应用程序上）将额外的声明添加到cookie中，它会在用户注销之前提供声明。

有两个（可能是多个）选项：

首先使用openidconnect身份验证的OnTicketReceived：

    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;
            }
        }
    });

或使用OnSigningIn Cookie身份验证事件

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
         }
     }
});
