如何在ASP.NET Core MVC中基于用户表中的字段添加声明? [英] How to add claims based on the fields from users table in ASP.NET Core MVC?

问题描述

如何基于ASP.NET Core MVC的用户表中保存的部门名称添加声明?我有多个属于不同部门的用户.

How to add claim based on the name of department that is saved in users table in ASP.NET Core MVC? I have multiple users that belong to different departments.

我要根据他们的部门提出索赔.请指导我如何执行此操作.

Depending on their departments I want to create claims. Please guide me how to do this.

我知道如何使用声明存储来创建和编辑用户或删除用户声明，但上述问题却没有.

I know how to create and edit users or delete users claims using claims store but not the above problem.

推荐答案

根据您的描述，建议您创建一个继承UserClaimsPrincipalFactory的自定义声明工厂.

According to your description, I suggest you could create a custom claim factory which inherits UserClaimsPrincipalFactory.

然后，您可以将其他声明添加到重写GenerateClaimsAsync方法中.

Then you could add the additional claims in the override GenerateClaimsAsync method.

更多详细信息，您可以参考以下代码:

MyUserClaimsPrincipalFactory:

MyUserClaimsPrincipalFactory:

using IdentityTestDemo.Data;
using Microsoft.AspNetCore.Identity;
using Microsoft.Extensions.Options;
using System.Linq;
using System.Security.Claims;
using System.Threading.Tasks;

namespace IdentityTestDemo
{
    public class MyUserClaimsPrincipalFactory : UserClaimsPrincipalFactory<IdentityUser>
    {
        private ApplicationDbContext _appliationDbContext;
        public MyUserClaimsPrincipalFactory(
        UserManager<IdentityUser> userManager,
        IOptions<IdentityOptions> optionsAccessor,ApplicationDbContext applicationDbContext)
            : base(userManager, optionsAccessor)
        {
            _appliationDbContext = applicationDbContext;
        }

        protected override async Task<ClaimsIdentity> GenerateClaimsAsync(IdentityUser user)
        {
           //get the data from dbcontext
           var Iuser=   _appliationDbContext.Users.Where(x => x.EmailConfirmed == true).FirstOrDefault();

            var identity = await base.GenerateClaimsAsync(user);
            //Get the data from EF core

            identity.AddClaim(new Claim("EmailTest", Iuser.Email));
            return identity;
        }
    }
}

Startup.cs:

Startup.cs：

    public void ConfigureServices(IServiceCollection services)
    {
        services.AddDbContext<ApplicationDbContext>(options =>
            options.UseSqlServer(
                Configuration.GetConnectionString("DefaultConnection")));
        services.AddDefaultIdentity<IdentityUser>(options => options.SignIn.RequireConfirmedAccount = true)
            .AddEntityFrameworkStores<ApplicationDbContext>().AddClaimsPrincipalFactory<MyUserClaimsPrincipalFactory>(); ;
        services.AddControllersWithViews();
        services.AddRazorPages();
    }

在控制器中获取索赔:

        var result = User.FindFirst("EmailTest").Value;

结果:
