c# - ASP .Net Core 身份角色声明未添加到用户

Question

我在使用角色/声明时遇到问题。

我已经创建了角色并给出了角色声明。然后将这些角色分配给用户，根据我在网上阅读的内容，这意味着用户应该继承角色声明，但他们没有。该政策无效，经过进一步检查，我在通过 JSON 输出用户声明时看不到声明。

如我所见，所有数据都保存在数据库中。

角色/声明播种者

 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();

    }

用户播种者

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();

我正在做的检查是

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

返回用于身份验证的基本 JSON 声明

[{"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"}]

我不确定问题出在哪里，并且已经在 google/stackoverflow 上搜索了一段时间但没有成功。

任何帮助将不胜感激

如果您使用的是 .Net Core 2.1，您似乎需要根据 this issue 更改默认身份配置。 .

在 .Net Core 2.1 中，您可以先创建自己的 ApplicationUser:

public class ApplicationUser : IdentityUser
{
}

修改你的数据库上下文:

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

使用旧式 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>();

然后为用户和角色播种:

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，注销并重新登录帐户， claim 应该在那里:

如果您使用的是 .Net Core 2.0，您的代码应该使用默认标识模板。
