Csharp 在 SignalR Hub 的 OnConnectedOnDisconnected 中注入租户信息

有一个多租户SaaS应用程序，我想在其中为SignalR Hub的OnConnectedAsync/OnDisconnectedAsync挂钩中的每tenantId个创建组.

问题是ITenancyContext<ApplicationTenant>被注册为作用域服务，这意味着它只在请求的作用域内可用.在SignalR集线器的上下文中，它与请求没有关联，因此它不可用.

那么我怎么才能让它变得可用呢？授权它并以某种方式丰富索赔吗？

public sealed class NotificationHub : Hub
{
    readonly ILogger<NotificationHub> _logger;
    readonly Guid _tenantId;

    public NotificationHub(ILogger<NotificationHub> logger, ITenancyContext<ApplicationTenant> tenancyContext) => (_logger, _tenantId) = (logger, tenancyContext.Tenant.Id);

    public override async Task OnConnectedAsync()
    {
        await JoinGroup(_tenantId.ToString());
        _logger.LogInformation("{ConnectionId} has connected to the hub. TenantId: {TenantId}", Context.ConnectionId, _tenantId);
        await base.OnConnectedAsync();
    }

    public override async Task OnDisconnectedAsync(Exception? exception)
    {
        await LeaveGroup(_tenantId.ToString());
        _logger.LogInformation("{ConnectionId} was disconnected from the hub. TenantId: {TenantId}", Context.ConnectionId, _tenantId);
        await base.OnDisconnectedAsync(exception);
    }

    Task JoinGroup(string groupName) => Groups.AddToGroupAsync(Context.ConnectionId, groupName);

    Task LeaveGroup(string groupName) => Groups.RemoveFromGroupAsync(Context.ConnectionId, groupName);
}
