azure - 在本地测试 Azure 托管的 WebApi 以将推送通知发送到所有设备

Question

如果我的问题很愚蠢，我深表歉意，但我是 WebApi 的新手。我已按照教程并将 WebApi 发布到 Azure。我还创建了一个 Xamarin 移动应用程序和 Azure 中的所有框架，以便能够向 Android 和 iOS 发送推送通知。我设置了通知中心、应用程序服务、托管 Web API 的 Web 服务等。使用“推送”选项卡向 Azure 进行测试以分别向 ios 和 android 发送通知，效果非常好。

我发布了Web api的代码。如何在我的计算机上本地使用 Web api 向两个平台(ios 和 android)发送通知？

            // send the message so that all template registrations that contain "messageParam"
            // will receive the notification. This includes APNS, GCM, WNS and MPNS template registrations.

                result = await hub.SendTemplateNotificationAsync(templateParams).ConfigureAwait(false);

            else

            // Write the success result to the logs.
            config.Services.GetTraceWriter().Info(result.State.ToString());
            return result;
        }


    }
}

在 Xamarin 中，有两种方法可以将推送通知从服务器发送到客户端。即使在 Microsoft 论坛上，也非常明确地提到了实现步骤。

1. 使用 Azure Hub 通知，我们可以在跨移动平台或 native 上轻松发送通知

另一个应用程序中心推送通知实现。
