与虚拟主机一起托管单例服务

Question

我需要一个服务来处理来自多个不同服务的传入 webhook 负载，并将它们传递给正确的实现进行处理。

我不确定我是否/应该在何处实例化我的协调器服务，它应该与 IHostBuilder 一起运行应用程序的生命周期。我应该创建一个 Thread 并在那里启动我的协调器吗？

服务接口

public interface IService
{
    event WorkCreated(object processedPayload);
    void ProcessWebhook(string payload);
}

Startup.cs

public void ConfigureServices(IServiceCollection services)
{
    services.AddSingleton<IService, Service1>();
    services.AddSingleton<IService, Service2>();
    services.AddSingleton<IService, Service3>();
}

协调员服务

public Class Coordinator
{
    public Coordinator(IList<IService> services
    {
        foreach service
            service.WorkCreated += eventHandler;
    }

    public eventHandler()
    {
        ...
    }
}

控制器

public class WebhookController : ControllerBase
{

    public WebhookController(IList<IService> services
    {
        ...
    }

    public ActionResult Webhook(string payload)
    {
        // Check which implementation to use by the header
        var referrer = this.Request.Headers["Referer"];

        if (referrer == "service1.com")
        {
            var serviceToUse = services.Where(s => s.GetType() == typeof(Service1));
            serviceToUse.ProcessWebhook(payload);
        }

        return Ok();
    }
