覆盖 FindByEmail 以按租户查找

Question

我有一个多租户应用程序，其中租户共享同一个数据库，因此意味着用户存储是共享的。

因此，我创建了自己的 UserStore，如下所示：

public class ApplicationUserStore : UserStore<ApplicationUser>
{
    public int TenantId { get; set; }

    public ApplicationUserStore(IdentityDbContext dbContext)
    : base(dbContext)
    {
    }

    public override Task<IdentityResult> CreateAsync(ApplicationUser user, CancellationToken cancellationToken = default)
    {
        user.TenantId = TenantId;
        return base.CreateAsync(user, cancellationToken);
    }

    public override Task<ApplicationUser> FindByEmailAsync(string normalizedEmail, CancellationToken cancellationToken = default)
    {
        return base.FindByEmailAsync(normalizedEmail, cancellationToken);
    }
}

我遇到的问题是我不确定如何添加到 FindByEmailAsync 调用以获取具有相应电子邮件和租户的用户。

我该如何解决这个问题？我正在使用 .NET Core 2.2 并查看本指南：https://www.scottbrady91.com/ASPNET-Identity/Quick-and-Easy-ASPNET-Identity-Multitenancy?fbclid=IwAR3F2NmmCoSHfxvIPwpQ0l-gTthFfVICaTdU2etcHyN--UEm-Nd6OP0LnLE 看起来 GetUserAggregateAsync 已从 2.2

中删除

对于租户过滤器，您可以尝试 Global Query Filters 就像

public class ApplicationDbContext : IdentityDbContext<SystemUser,IdentityRole<int>,int>
{
    public ApplicationDbContext(DbContextOptions<ApplicationDbContext> options)
        : base(options)
    {
    }
    public int TenantId { get; set; }
    protected override void OnModelCreating(ModelBuilder builder)
    {
        base.OnModelCreating(builder);
        // Customize the ASP.NET Identity model and override the defaults if needed.
        // For example, you can rename the ASP.NET Identity table names and more.
        // Add your customizations after calling base.OnModelCreating(builder);
        builder.Entity<SystemUser>().HasQueryFilter(b => EF.Property<int>(b, "TenantId") == TenantId);
    }
}

否则，您可能需要参考GetUserAggregateAsync

实现自己的GetUserAggregateAsync
