在C＃中使用Webpush发送通知后没有响应

Question

我正在使用Webpush库向web应用程序发送webpush通知，我已经开发了用于发送推送通知的API，在命令API中有一个名为 SendNotification 的库中的方法，没有响应即将到来。[ [1]：https://i.stack.imgur.com/fuwpP.png][1]

public HttpResponseMessage sendNotification(Notification notify)
    {
        try
        {
            var subscription = new PushSubscription(notify.endPoint, notify.p256dh, notify.auth);
            if (subscription != null)
            {
                client.SendNotification(subscription, "clarifide notification received");
                return Request.CreateResponse(HttpStatusCode.OK, notify);
            }
            else
            {
                return Request.CreateErrorResponse(HttpStatusCode.InternalServerError, "Internal Server Error");
            }
        }
        catch (WebPushException e)
        {

            return Request.CreateErrorResponse(HttpStatusCode.InternalServerError, e.Message);
        }
    }
