添加自定义声明在 asp.net 核心身份中不起作用

Adding custom claim not working in asp.net core identity(添加自定义声明在 asp.net 核心身份中不起作用)

本文介绍了添加自定义声明在 asp.net 核心身份中不起作用的处理方法,对大家解决问题具有一定的参考价值,需要的朋友们下面随着小编来一起学习吧!

问题描述

我创建了 CustomClaimType 来存储 user id:

I have created CustomClaimType to store user id:

public static class CustomClaimTypes
{
    public const string UserId = "UserId";
}

当用户登录时,我设置它:

When user login, I set it:

var claims = new List<Claim>();
claims.Add(new Claim(ClaimTypes.Name, doc_session.ufname + " " + doc_session.ulname));
claims.Add(new Claim(CustomClaimTypes.UserId, doc_session.isci_id.Value.ToString()));
ClaimsIdentity userIdentity = new ClaimsIdentity(claims,"Identity.Application");
ClaimsPrincipal principal = new ClaimsPrincipal(userIdentity);

我还创建了自定义身份扩展:

I have also created custom identity extension:

public static class IdentityExtensions
{
    public static int GetUserId(this IIdentity identity)
    {
        ClaimsIdentity claimsIdentity = identity as ClaimsIdentity;
        Claim claim = claimsIdentity?.FindFirst(CustomClaimTypes.UserId);

        if (claim == null)
            return 0;

        return int.Parse(claim.Value);
    }

    public static string GetName(this IIdentity identity)
    {
        ClaimsIdentity claimsIdentity = identity as ClaimsIdentity;
        Claim claim = claimsIdentity?.FindFirst(ClaimTypes.Name);

        return claim?.Value ?? string.Empty;
    }
}

但是当我调用 User.Identity.GetUserId(); 我得到 0 (null) 结果.

But when I call User.Identity.GetUserId(); I get 0 (null) as result.

推荐答案

要向 Identity 添加额外的声明,您可以实现自定义 CustomClaimsPrincipalFactory.

For adding extra claims to Identity, you could implement custom CustomClaimsPrincipalFactory.

  1. CustomClaimsPrincipalFactory

public class CustomClaimsPrincipalFactory : UserClaimsPrincipalFactory<IdentityUser<int>>
{
    public CustomClaimsPrincipalFactory(UserManager<IdentityUser<int>> userManager,
                                            IOptions<IdentityOptions> optionsAccessor)
    : base(userManager, optionsAccessor)
    {
    }

    public async override Task<ClaimsPrincipal> CreateAsync(IdentityUser<int> user)
    {
        var principal = await base.CreateAsync(user);

        // Add your claims here
        ((ClaimsIdentity)principal.Identity).AddClaims(
            new[] { new Claim(ClaimTypes.Name, user.UserName),
            new Claim(CustomClaimTypes.UserId, user.Id.ToString())
            });

        return principal;
    }
}

  • 注册CustomClaimsPrincipalFactory

    public void ConfigureServices(IServiceCollection services)
    {
        services.Configure<CookiePolicyOptions>(options =>
        {
            // This lambda determines whether user consent for non-essential cookies is needed for a given request.
            options.CheckConsentNeeded = context => true;
            options.MinimumSameSitePolicy = SameSiteMode.None;
        });
    
        services.AddDbContext<ApplicationDbContext>(options =>
            options.UseSqlServer(
                Configuration.GetConnectionString("DefaultConnection")));
        services.AddDefaultIdentity<IdentityUser<int>>()
            .AddEntityFrameworkStores<ApplicationDbContext>();
        services.AddScoped<IUserClaimsPrincipalFactory<IdentityUser<int>>, CustomClaimsPrincipalFactory>();
        services.AddMvc().SetCompatibilityVersion(CompatibilityVersion.Version_2_1);
    }
    

  • IdentityExtensions

    public static class IdentityExtensions
    {
        public static int GetUserId(this ClaimsPrincipal identity)
        {
            Claim claim = identity?.FindFirst(CustomClaimTypes.UserId);
    
            if (claim == null)
                return 0;
    
            return int.Parse(claim.Value);
        }
    
        public static string GetName(this ClaimsPrincipal identity)
        {
            Claim claim = identity?.FindFirst(ClaimTypes.Name);
    
            return claim?.Value ?? string.Empty;
        }
    }
    

  • 用途

  • Useage

    public IActionResult About()
    {
        var claims = User.Claims;
        var userId = User.GetUserId();
        var userName = User.GetName();
        ViewData["Message"] = "Your application description page.";
    
        return View();
    }
