User.Identity.GetUserId() && User.IsInRole( "rolename" ) 不起作用

Question

我正在尝试自定义ASP Identity 2.0以使用Guid Key。 我可以登录 a-ok，但在尝试获取用户数据时遇到了一些问题。

这些都不起作用：

User.Identity.GetUserId() [始终作为空字符串返回]

User.IsInRole("rolename") [始终返回为假]

User.Identity.Name 已填充。

我的登录处理程序

public class CommandHandler : IRequestHandler<ViewModel, Result>
{
    private readonly GuidUserManager _manager;
    public CommandHandler(GuidUserManager manager)
    {
        _manager = manager;
    }
    public Result Handle(ViewModel criteria)
    {
        // Verify if a user exists with the provided identity information
        var user = _manager.Find(criteria.UserName, criteria.Password);
        // If a user was found
        if (user == null)
            return Result.Fail("Invalid username or password.");
        // Clear any lingering authencation data
        FormsAuthentication.SignOut();
        // Write the authentication cookie
        FormsAuthentication.SetAuthCookie(user.UserName, criteria.RememberMe);
        return Result.Ok();
    }
}

我的身份代码

using System;

using System.Threading.Tasks;
using Microsoft.AspNet.Identity;
using Microsoft.AspNet.Identity.EntityFramework;
namespace FM.Web.Security
{
    public class GuidUserDbContext : IdentityDbContext<GuidUser, GuidRole, Guid, GuidUserLogin, GuidUserRole, GuidUserClaim>
    {
        public GuidUserDbContext(string connection)
            : base(connection)
        {
            Database.SetInitializer(new GuidUserDbContextInitialilser());
        }
    }
    public class GuidUserDbContextInitialilser : CreateDatabaseIfNotExists<GuidUserDbContext>
    {
    }
    public class GuidUserManager : UserManager<GuidUser, Guid>
    {
        public GuidUserManager(GuidUserStore userStore)
            : base(userStore)
        {
        }
    }
    public class GuidUserLogin : IdentityUserLogin<Guid>

    }
    public class GuidUserStore : UserStore<GuidUser, GuidRole, Guid, GuidUserLogin, GuidUserRole, GuidUserClaim>
    {
        public GuidUserStore(DbContext context)
            : base(context)
        {
        }
    }
    public class GuidRoleStore : RoleStore<GuidRole, Guid, GuidUserRole>
    {
        public GuidRoleStore(DbContext context)
            : base(context)
        {
        }
    }
    public class GuidUser : IdentityUser<Guid, GuidUserLogin, GuidUserRole, GuidUserClaim>
    {
    }
}

Answer 1

您需要在帐户控制器中使用此代码

public GuidUserManager UserManager
{
    get
    {
        return _userManager ?? HttpContext.GetOwinContext().GetUserManager<GuidUserManager>();
    }
    private set
    {
        _userManager = value;
    }
}

Answer 2

FormsAuthentication是你的问题。可能您的web.config包含与MembershipRoleProvider相关的条目 - 弄乱User.IsInRole.删除与表单身份验证相关的所有代码/配置以解决您的问题。
