Question

我正在尝试为我的React ASP.NET Core应用程序使用身份设置授权。我正在关注ASP.NET Core文档：Docs

在前面的示例中，我在文档中引用“ ApplicationContext”的地方都使用了“ UserDBContext”，但在这种情况下我遇到了错误。

当我尝试配置'AddIdentityServer'服务时遇到错误。在我的Startup.cs

完全错误：

The type 'projectName.UserDBContext' cannot be used as type parameter 'TContext' in the generic type or method 'IdentityServerBuilderConfigurationExtensions.AddApiAuthorization<TUser, TContext>(IIdentityServerBuilder)'. There is no implicit reference conversion from 'projectName.UserDBContext' to 'IdentityServer4.EntityFramework.Interfaces.IPersistedGrantDbContext'

User.cs：

namespace project {

    public class User : IdentityUser {

        [DataType (DataType.Date)]
        public DateTime created { get; set; }

        [Key]
        [Required]
        public string email { get; set; }

        [Required]
        public string firstname { get; set; }

        [Required]
        public string lastname { get; set; }

        [Required]
        [Range (1, 100)]
        public string username { get; set; }

        [Required]
        [StringLength (100)]
        public string password { get; set; }

    }

    public class UserDBContext : IdentityDbContext {

        public DbSet<User> users { get; set; }

        public UserDBContext (DbContextOptions<UserDBContext> options) : base (options) { }

    }
}

Startup.cs

        public void ConfigureServices (IServiceCollection services) {

            services.AddControllersWithViews ();

            services.AddSpaStaticFiles (configuration => {
                configuration.RootPath = "ClientApp/build";
            });

            services.AddDbContext<UserDBContext> (options =>
                options.UseNpgsql (Configuration.GetConnectionString ("DefaultConnection")));

            services.AddDefaultIdentity<User> ()
                .AddEntityFrameworkStores<UserDBContext> ();

            services.AddIdentityServer()
                .AddApiAuthorization<User, UserDBContext>();


            services.AddAuthentication ()
                .AddIdentityServerJwt ();

        }

这是给我错误的代码：

            services.AddIdentityServer()
                .AddApiAuthorization<User, UserDBContext>();

尝试类似的事情：

public class UserDBContext : IdentityDbContext,IPersistedGrantDbContext {

    public DbSet<User> users { get; set; }

    public UserDBContext (DbContextOptions<UserDBContext> options) : base (options) { }

}

在方法'AddApiAuthorization <TUser，TContext>'的通用类型中，类型UserDBContext不能用作类型参数'TContext'。
