ASP .Net Core身份角色聲明未添加到用戶

Question

我在使用角色/索賠時遇到問題。

我已經創建了角色，並給出了角色聲明。 然后將這些角色分配給用戶，根據我在網上閱讀的內容，這意味着用戶應繼承角色聲明，但不能繼承。 該政策無效，經進一步檢查，通過JSON輸出用戶聲明時，我看不到聲明。

如我所見，所有數據都保存在數據庫中。

角色/要求播種者

 public static void SeedRolesAndClaims(RoleManager<IdentityRole> roleManager)
    {
        // Create Roles
        IdentityRole adminRole = new IdentityRole("Admin");
        roleManager.CreateAsync(adminRole).Wait();

        roleManager.AddClaimAsync(adminRole, new Claim(ClaimTypes.AuthorizationDecision, "edit.post")).Wait();
        roleManager.AddClaimAsync(adminRole, new Claim(ClaimTypes.AuthorizationDecision, "delete.post")).Wait();
        roleManager.AddClaimAsync(adminRole, new Claim(ClaimTypes.AuthorizationDecision, "create.post")).Wait();
        roleManager.AddClaimAsync(adminRole, new Claim(ClaimTypes.AuthorizationDecision, "view.post")).Wait();
        roleManager.AddClaimAsync(adminRole, new Claim(ClaimTypes.AuthorizationDecision, "create.comment")).Wait();

        IdentityRole userRole = new IdentityRole("User");
        roleManager.CreateAsync(userRole).Wait();
        roleManager.AddClaimAsync(userRole, new Claim(ClaimTypes.AuthorizationDecision, "create.comment")).Wait();

    }

用戶播種者

ApplicationUser user = new ApplicationUser { UserName = "john@email.com", FirstName = "Admin", LastName = "Smith", Email = "john@email.com" };
        userManager.CreateAsync(user, "Password123*").Wait();
        userManager.AddToRoleAsync(user, "Admin").Wait();

我正在做的檢查是

        var claims = User.Claims.Select(claim => new { claim.Type, claim.Value }).ToArray();
        return Json(claims);

它返回用於身份驗證的基本JSON聲明

[{"type":"http://schemas.xmlsoap.org/ws/2005/05/identity/claims/nameidentifier","value":"05bef53e-dd97-41f6-beee-531501cf8598"},{"type":"http://schemas.xmlsoap.org/ws/2005/05/identity/claims/name","value":"john@email.com"},{"type":"AspNet.Identity.SecurityStamp","value":"SGS23ZGIY6UYOOL2APWRIZKNT2V6QBJC"}]

我不確定是什么問題，並且已經在google / stackoverflow上搜索了一段時間而沒有成功。

任何幫助將不勝感激

如果使用的是.Net Core 2.1，則似乎需要根據此問題更改默認的Identity配置。

在.Net Core 2.1中，您可以首先創建自己的ApplicationUser ：

public class ApplicationUser : IdentityUser
{
}

修改您的dbcontext：

public class ApplicationDbContext : IdentityDbContext<ApplicationUser, IdentityRole, string>
{
    public ApplicationDbContext(DbContextOptions<ApplicationDbContext> options)
        : base(options)
    {
    }
}

使用舊式api配置身份：

services.AddDbContext<ApplicationDbContext>(options =>
    options.UseSqlServer(
        Configuration.GetConnectionString("DefaultConnection")));
services.AddIdentity<ApplicationUser, IdentityRole>()
.AddRoleManager<RoleManager<IdentityRole>>()
.AddDefaultUI()
.AddDefaultTokenProviders()
.AddEntityFrameworkStores<ApplicationDbContext>();

並播種用戶和角色，例如：

private async Task CreateUserRoles(IServiceProvider serviceProvider)
{
    var RoleManager = serviceProvider.GetRequiredService<RoleManager<IdentityRole>>();
    var UserManager = serviceProvider.GetRequiredService<UserManager<ApplicationUser>>();

    IdentityResult roleResult;
    //Adding Admin Role
    var roleCheck = await RoleManager.RoleExistsAsync("Admin");
    if (!roleCheck)
    {

        IdentityRole adminRole = new IdentityRole("Admin");
        //create the roles and seed them to the database
        roleResult = await RoleManager.CreateAsync(adminRole);

        RoleManager.AddClaimAsync(adminRole, new Claim(ClaimTypes.AuthorizationDecision, "edit.post")).Wait();
        RoleManager.AddClaimAsync(adminRole, new Claim(ClaimTypes.AuthorizationDecision, "delete.post")).Wait();

        ApplicationUser user = new ApplicationUser { UserName = "v-nany@hotmail.com", Email = "v-nany@hotmail.com" };
        UserManager.CreateAsync(user, "xxxxxx").Wait();

        await UserManager.AddToRoleAsync(user, "Admin");
    }

}

// This method gets called by the runtime. Use this method to configure the HTTP request pipeline.
public void Configure(IApplicationBuilder app, IHostingEnvironment env ,IServiceProvider serviceProvider)
{
    if (env.IsDevelopment())
    {
        app.UseDeveloperExceptionPage();
        app.UseDatabaseErrorPage();
    }
    else
    {
        app.UseExceptionHandler("/Home/Error");
        app.UseHsts();
    }

    app.UseHttpsRedirection();
    app.UseStaticFiles();
    app.UseCookiePolicy();

    app.UseAuthentication();

    app.UseMvc(routes =>
    {
        routes.MapRoute(
            name: "default",
            template: "{controller=Home}/{action=Index}/{id?}");
    });

    CreateUserRoles(serviceProvider).Wait();
}

最后，注銷並重新登錄帳戶，索賠應該在以下位置：

如果使用的是.Net Core 2.0，則您的代碼應使用默認的身份模板。
