如何创建UserManager的实例



我正在努力学习新的asp.net身份2.0是如何工作的,但由于文档很少,我遇到了不少障碍。

我在下面的代码是基于我读过的几个教程:

public class CustomRole : IdentityRole<string, CustomUserRole>
{
    public CustomRole() { }
    public CustomRole(string name) { Name = name; }
}
public class CustomUserRole : IdentityUserRole<string> { }
public class CustomUserClaim : IdentityUserClaim<string> { }
public class CustomUserLogin : IdentityUserLogin<string> { }
// define the application user
public class ApplicationUser : IdentityUser<string, CustomUserLogin, CustomUserRole, 
    CustomUserClaim>
{
    [Required]
    public bool IsActive { get; set; }
    public async Task<ClaimsIdentity> GenerateUserIdentityAsync(UserManager<ApplicationUser> manager)
    {
        // Note the authenticationType must match the one defined in CookieAuthenticationOptions.AuthenticationType
        var userIdentity = await manager.CreateIdentityAsync(this, DefaultAuthenticationTypes.ApplicationCookie);
        // Add custom user claims here
        return userIdentity;

    }
}
public partial class myDbContext : IdentityDbContext<ApplicationUser, CustomRole, string, 
    CustomUserLogin, CustomUserRole, CustomUserClaim>
{
    static myDbContext()
    {
        Database.SetInitializer<myDbContext>(null);
    }
    public myDbContext()
        : base("Name=myDbContext")
    {
    }
    public DbSet<TestTable> TestTables { get; set; }
    protected override void OnModelCreating(DbModelBuilder modelBuilder)
    {
        modelBuilder.Configurations.Add(new TestTableMap());
    }
}

然后我有了这个代码:

// create the user manager
        UserManager = new UserManager<ApplicationUser>(new UserStore<ApplicationUser, CustomRole, string, CustomUserLogin, CustomUserRole,
    CustomUserClaim>(
            new myDbContext()));

我在该语句中得到一个错误,该错误表示参数类型为UserStore&lt-ApplicationUser,CustomRole,字符串,CustomUserLogin,CustomUserRole,CustomUserClaim->不可分配给参数类型IUserStore&lt-应用程序用户->

我在这里错过了什么?

试试这个:

UserManager = new UserManager<ApplicationUser,string>(new UserStore<ApplicationUser, CustomRole, string, CustomUserLogin, CustomUserRole, CustomUserClaim>(new myDbContext()));

注意,我对UserManager使用了不同的构造,我添加了string作为ApplicationUser主键代码中使用的第二种类型

由于您以这种方式实现了自定义用户/角色等,因此需要在整个代码中使用UserManager作为UserManager<ApplicationUser,string>,以字符串形式传入用户PK的类型。

这对我很有效。如果你创建自定义用户和角色,似乎你必须创建自己的用户管理器和用户存储。这是派生的UM(您也可以以与角色管理器相同的方式创建):

public class ApplicationUserManager : UserManager<ApplicationUser, string>
    {
        public ApplicationUserManager(IUserStore<ApplicationUser, string> store)
            : base(store)
        {
        }

    }
public class ApplicationUserStore : UserStore<ApplicationUser, CustomRole, string, CustomUserLogin, CustomUserRole, CustomUserClaim>
    {
        public ApplicationUserStore(ApplicationDbContext context)
            : base(context)
        {
        }
    }

然后创建UserManager:

ApplicationUserManager um = new ApplicationUserManager(new ApplicationUserStore(new ApplicationDbContext()));
