使用UserClaimsPrincipalFactory定义声明

问题描述

几天来，我尝试声明Blazor申请的索赔。我终于找到了一种可行的方法，但是由于某种原因，我无法在索赔清单中找到索赔。 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>();

有人可以帮助我找到我的代码有什么问题吗？ 预先谢谢你。

更新

感谢Brian Parker为我铺平了道路。为了使它在其他人需要的情况下起作用，我像这样更改了AppClaimsPrincipalFactory类：

public class AppClaimsPrincipalFactory : UserClaimsPrincipalFactory<ApplicationUser>
{
    public AppClaimsPrincipalFactory(UserManager<ApplicationUser> 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: ["[e-mail]","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Brian Parker。你让我开心。

解决方法

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);

});
