C# 覆盖FindByEmail以按租户查找

我有一个多租户应用程序，租户共享同一个数据库，这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);
    }
}

public class ApplicationUserStore:UserStore看起来像是从2.2版中剥离出来的
GetUserAggregateAsync
对于租户筛选器，您可以

public类ApplicationDbContext:IdentityDbContext
{
公共应用程序DBContext（DbContextOptions

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);
    }
}
