使用 UserClaimsPrincipalFactory 定义声明

Question

几天来，我一直在尝试声明 Blazor 应用程序的声明。我终于找到了一种应该可行的方法，但由于某种原因，我无法在索赔列表中找到我的索赔。我创建了以下 AppClaimsPrincipalFactory：

public class AppClaimsPrincipalFactory : UserClaimsPrincipalFactory<ApplicationUser>
{
    public AppClaimsPrincipalFactory(UserManager<ApplicationUser> userManager, IOptions<IdentityOptions> optionsAccessor) : base(userManager, optionsAccessor)
    {
    }
    public override async Task<ClaimsPrincipal> CreateAsync(ApplicationUser user)
    {
        var id = await GenerateClaimsAsync(user);
        if (user != null)
        {
            id.AddClaim(new Claim(ClaimTypes.GivenName, user.FirstName));
        }
        return new ClaimsPrincipal(id);


        var principal = await base.CreateAsync(user);

        if (!string.IsNullOrWhiteSpace(user.FirstName))
        {
            ((ClaimsIdentity)principal.Identity).AddClaim(new Claim(ClaimTypes.GivenName, user.FirstName));
        }

        if (!string.IsNullOrWhiteSpace(user.LastName))
        {
            ((ClaimsIdentity)principal.Identity).AddClaim(new Claim(ClaimTypes.Surname, user.LastName));
        }

        return principal;
    }
}

我在 Startup.cs 文件的 ConfigureServices 中添加了以下代码：

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

有人可以帮我找出我的代码有什么问题吗？提前谢谢你。

更新

感谢 Brian Parker 为我铺平了道路。为了让它在其他人需要它的情况下工作，我像这样更改了 AppClaimsPrincipalFactory class：

public class AppClaimsPrincipalFactory : UserClaimsPrincipalFactory<ApplicationUser>
{
    public AppClaimsPrincipalFactory(UserManager<ApplicationUser> userManager, IOptions<IdentityOptions> optionsAccessor) : base(userManager, optionsAccessor)
    {
    }
    protected override async Task<ClaimsIdentity> GenerateClaimsAsync(ApplicationUser user)
    {
        ClaimsIdentity claims = await base.GenerateClaimsAsync(user);
        claims.AddClaim(new Claim("name", "Aris"));
        claims.AddClaim(new Claim("customClaim", "test value"));
        claims.AddClaim(new Claim(ClaimTypes.GivenName, user.FirstName));
        claims.AddClaim(new Claim(ClaimTypes.Surname, user.LastName));
        return claims;
    }
}

我还更改了 Startup.cs 文件中的代码 services.AddDefaultIdentity：

services.AddDefaultIdentity<ApplicationUser>(options => options.SignIn.RequireConfirmedAccount = true)
    .AddRoles<IdentityRole>()
    .AddEntityFrameworkStores<ApplicationDbContext>()
    .AddClaimsPrincipalFactory<AppClaimsPrincipalFactory>();

因此具有以下声明值：

name: ["myemail@hotmail.com","Aris"]
customClaim: test value
http://schemas.xmlsoap.org/ws/2005/05/identity/claims/givenname: Aristotelis
http://schemas.xmlsoap.org/ws/2005/05/identity/claims/surname: Pitaridis

谢谢布莱恩·帕克。你成就了我的一天。

尝试：

services.AddScoped<AppClaimsPrincipalFactory>();

services.AddDefaultIdentity<ApplicationUser>(options => options.SignIn.RequireConfirmedAccount = true)
    .AddRoles<IdentityRole>()
    .AddEntityFrameworkStores<ApplicationDbContext>()
    .AddClaimsPrincipalFactory<AppClaimsPrincipalFactory>();

services.AddIdentityServer()
    .AddApiAuthorization<ApplicationUser, ApplicationDbContext>(options =>
{
    options.IdentityResources["openid"].UserClaims.Add(ClaimTypes.GivenName);
    options.ApiResources.Single().UserClaims.Add(ClaimTypes.GivenName);

    options.IdentityResources["openid"].UserClaims.Add(ClaimTypes.Surname);
    options.ApiResources.Single().UserClaims.Add(ClaimTypes.Surname);

});
