ASP .NET Core Identity 自定义 ApiAuthorizationDbContext

Question

我正在使用带有 Angular 项目的 ASP .NET Core 3.0。我看到了这个新的ApiAuthorizationDbContext，我想覆盖表名和用户 ID（到 int），但我无法做到。有人知道技巧吗？

这是用于覆盖表名的上下文类，但它会创建 AspNetUser 和 User 表。为什么不像往常一样创建一个？

public class ApplicationDbContext : ApiAuthorizationDbContext<AppUser>
    {
        public ApplicationDbContext(
            DbContextOptions options,
            IOptions<OperationalStoreOptions> operationalStoreOptions) : base(options, operationalStoreOptions)
        {
        }

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

            modelBuilder.Entity<AppUser>(entity => { entity.ToTable(name: "User"); });
            modelBuilder.Entity<AppRole>(entity => { entity.ToTable(name: "Role"); });
        }
    }

这是我的用户：

public class AppUser : IdentityUser
{
}

通常我用AppUser<int> 覆盖主键，但由于ApiAuthorizationDbContext，它不起作用。

有什么想法吗？

Answer 1

要使用ApiAuthorizationDbContext 自定义用户和角色表，您可以按照以下步骤操作：

1. 使用身份创建 Asp.Net Core Angular 模板

2. 添加用户和角色类

   public class AppUser : IdentityUser<int>
   {
   }
   public class AppRole : IdentityRole<int>
   {
   }
   

3. 添加自定义ApiAuthorizationDbContext

   /// <summary>
   /// Database abstraction for a combined <see cref="DbContext"/> using ASP.NET Identity and Identity Server.
   /// </summary>
   /// <typeparam name="TUser"></typeparam>
   /// <typeparam name="TRole"></typeparam>
   /// <typeparam name="TKey">Key of the IdentityUser entity</typeparam>
   public class KeyApiAuthorizationDbContext<TUser, TRole, TKey> : IdentityDbContext<TUser, TRole, TKey>, IPersistedGrantDbContext
       where TUser : IdentityUser<TKey>
       where TRole : IdentityRole<TKey>
       where TKey : IEquatable<TKey>
   {
       private readonly IOptions<OperationalStoreOptions> _operationalStoreOptions;
   
       /// <summary>
       /// Initializes a new instance of <see cref="ApiAuthorizationDbContext{TUser, TRole, TKey}"/>.
       /// </summary>
       /// <param name="options">The <see cref="DbContextOptions"/>.</param>
       /// <param name="operationalStoreOptions">The <see cref="IOptions{OperationalStoreOptions}"/>.</param>
       public KeyApiAuthorizationDbContext(
           DbContextOptions options,
           IOptions<OperationalStoreOptions> operationalStoreOptions)
           : base(options)
       {
           _operationalStoreOptions = operationalStoreOptions;
       }
   
       /// <summary>
       /// Gets or sets the <see cref="DbSet{PersistedGrant}"/>.
       /// </summary>
       public DbSet<PersistedGrant> PersistedGrants { get; set; }
   
       /// <summary>
       /// Gets or sets the <see cref="DbSet{DeviceFlowCodes}"/>.
       /// </summary>
       public DbSet<DeviceFlowCodes> DeviceFlowCodes { get; set; }
   
       Task<int> IPersistedGrantDbContext.SaveChangesAsync() => base.SaveChangesAsync();
   
       /// <inheritdoc />
       protected override void OnModelCreating(ModelBuilder builder)
       {
           base.OnModelCreating(builder);
           builder.ConfigurePersistedGrantContext(_operationalStoreOptions.Value);
       }
   }
   
   /// <summary>
   /// Database abstraction for a combined <see cref="DbContext"/> using ASP.NET Identity and Identity Server.
   /// </summary>
   /// <typeparam name="TUser"></typeparam>
   public class ApiAuthorizationDbContext<TUser> : KeyApiAuthorizationDbContext<TUser, IdentityRole, string>
       where TUser : IdentityUser
   {
       /// <summary>
       /// Initializes a new instance of <see cref="ApiAuthorizationDbContext{TUser}"/>.
       /// </summary>
       /// <param name="options">The <see cref="DbContextOptions"/>.</param>
       /// <param name="operationalStoreOptions">The <see cref="IOptions{OperationalStoreOptions}"/>.</param>
       public ApiAuthorizationDbContext(
           DbContextOptions options,
           IOptions<OperationalStoreOptions> operationalStoreOptions)
           : base(options, operationalStoreOptions)
       {
       }
   }
   

4. 更改DbContext

   public class ApplicationDbContext : KeyApiAuthorizationDbContext<AppUser, AppRole, int>
   {
       public ApplicationDbContext(
           DbContextOptions options,
           IOptions<OperationalStoreOptions> operationalStoreOptions) : base(options, operationalStoreOptions)
       {
       }
       protected override void OnModelCreating(ModelBuilder modelBuilder)
       {
           base.OnModelCreating(modelBuilder);
   
           modelBuilder.Entity<AppUser>(entity => { entity.ToTable(name: "User"); });
           modelBuilder.Entity<AppRole>(entity => { entity.ToTable(name: "Role"); });
       }
   }
   

5. 注册用户和角色

   services.AddDefaultIdentity<AppUser>()
       .AddRoles<AppRole>()
       .AddEntityFrameworkStores<ApplicationDbContext>();
   
   services.AddIdentityServer()                
       .AddApiAuthorization<AppUser, ApplicationDbContext>();
   

6. 删除现有的Migrations（如果数据库存在，您可能需要删除它）。

7. 运行 add-migration 和 update-database 检查结果。

目前需要自定义ApiAuthorizationDbContext，这个问题已经通过ApiAuthorizationDbContext force TUser to extends IdentityUser instead of IdentityUser #9548和Add IdentityUser support to ApiAuthorizationDbContext #13064跟踪。获取新东方版本会有些延迟。
