Question

我正在使用带有角度项目的aspnet core 3.0。我看到了这个新的ApiAuthorizationDbContext，我想覆盖表名和用户ID（以int表示），但是我无法做到这一点。有人知道把戏吗？

这是上下文的类，在其中我告诉他覆盖表名，但是它创建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
{
}

通常我会用AppUser覆盖主键，但是由于ApiAuthorizationDbContext的原因，它无法正常工作。

有人知道吗？

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

创建具有身份的Asp.Net核心角度模板

添加用户和角色类

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

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)
    {
    }
}

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"); });
    }
}

注册用户和角色

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

services.AddIdentityServer()                
    .AddApiAuthorization<AppUser, ApplicationDbContext>();

删除现有的Migrations（如果数据库存在，则可能需要将其删除）。
运行添加迁移和更新数据库以检查结果。

当前，您需要自定义ApiAuthorizationDbContext，此问题已通过ApiAuthorizationDbContext force TUser to extends IdentityUser instead of IdentityUser #9548和Add IdentityUser support to ApiAuthorizationDbContext #13064进行了跟踪。取得最新版本会有些延迟。
