IdentityUser 充满了不必要的属性

问题描述 投票：0回答：1

我在 ASP.NET Core 8 中使用 Identity，并且在设置从 

ApplicationDbContext
继承的 
IdentityDbContext
时，Identity 要求我的 
ApplicationUser
从 
IdentityUser
继承。问题是我不希望我的 
ApplicationUser
类继承所有 
IndentityUser
的属性，因为我不需要它们。我不需要密码、LockoutEnabled 等，因为我使用 OAuth 进行身份验证。

如何设置一个被 

ApplicationUser
接受的 
IdentityDbContext
类而不继承 
IdentityUser
的任何属性？

我尝试取消映射它们，但即使如此，有些仍然被映射（请参阅迁移）

应用程序用户.cs

using Microsoft.AspNetCore.Identity;
using System.ComponentModel.DataAnnotations.Schema;

namespace Project.Models
{
    public class ApplicationUser : IdentityUser
    {
        [NotMapped]
        public override string? NormalizedUserName { get; set; }

        [NotMapped]
        public override string? Email { get; set; }

        [NotMapped]
        public override string? NormalizedEmail { get; set; }

        [NotMapped]
        public override string? PasswordHash { get; set; }

        [NotMapped]
        public override string? SecurityStamp { get; set; }

        [NotMapped]
        public override string? ConcurrencyStamp { get; set; }

        [NotMapped]
        public override string? PhoneNumber { get; set; }

        [NotMapped]
        public override bool PhoneNumberConfirmed { get; set; }

        [NotMapped]
        public override bool TwoFactorEnabled { get; set; }

        [NotMapped]
        public override DateTimeOffset? LockoutEnd { get; set; }

        [NotMapped]
        public override bool LockoutEnabled { get; set; }

        [NotMapped]
        public override int AccessFailedCount { get; set; }

        public string ProfilePicture { get; set; }
    }
}

ApplicationDbContext.cs

using Project.Models;
using Microsoft.AspNetCore.Identity;
using Microsoft.AspNetCore.Identity.EntityFrameworkCore;
using Microsoft.EntityFrameworkCore;

namespace Project
{
    public class ApplicationDbContext : IdentityDbContext<ApplicationUser>
    {
        private IConfiguration _configuration;

        public ApplicationDbContext(IConfiguration configuration)
        {
            _configuration = configuration;
        }

        protected override void OnConfiguring(DbContextOptionsBuilder optionsBuilder)
        {
            string connectionString = _configuration.GetConnectionString("Database");

            optionsBuilder.UseMySql(connectionString, ServerVersion.AutoDetect(connectionString));
        }

        protected override void OnModelCreating(ModelBuilder builder)
        {
            base.OnModelCreating(builder);

            builder.Entity<ApplicationUser>()
                .ToTable("Users");

            builder.Entity<IdentityRole>()
                .ToTable("Roles");
        }
    }
}

我已经使用 Fluent API 解决了这个问题

protected override void OnModelCreating(ModelBuilder builder)
{
    base.OnModelCreating(builder);

    builder.Entity<ApplicationUser>()
        .Ignore(u => u.EmailConfirmed)
        .Ignore(u => u.AccessFailedCount)
        .Ignore(u => u.ConcurrencyStamp)
        .Ignore(u => u.Email)
        .Ignore(u => u.LockoutEnabled)
        .Ignore(u => u.LockoutEnd)
        .Ignore(u => u.NormalizedEmail)
        .Ignore(u => u.NormalizedUserName)
        .Ignore(u => u.PasswordHash)
        .Ignore(u => u.PhoneNumber)
        .Ignore(u => u.PhoneNumberConfirmed)
        .Ignore(u => u.TwoFactorEnabled)
        .Ignore(u => u.SecurityStamp);
}
