与向服务器发出的普通请求相比，原始通知有什么优势？
我知道当您的应用程序处于非活动状态时，平铺通知和 Toast 通知会派上用场，但是原始通知相对于下一行的优势是什么？
WebClient( ).DownloadStringAsync( );
I know where Tile Notification and Toast Notification come in handy, when your app is inactive, but what is the advantage of Raw Notifications over the next line?
WebClient( ).DownloadStringAsync( );

原始通知允许您在应用程序运行时将自定义数据按需推送到应用程序。
WebClient.DownloadStringAsync允许您从服务器提取数据。Raw notifications allow you to push custom data on-demand to your application while it's running.
WebClient.DownloadStringAsyncallows you to pull data from a server.在很多情况下，原始通知可能最好与拉取请求一起使用。我倾向于纯粹使用通知来告诉正在运行的客户端 - 这可能是从新消息已到达服务器端（在这种情况下您可能希望在通知中发送消息）到“整个消息”的任何内容。服务器上的数据集已更新，您最好尽可能地过来并获取最新的更改”。
如前所述，您可以使用原始通知来发送所有必需的信息（如果它足够小），但在其他情况下，您很可能只是告诉应用程序需要给家里打电话以获取一些信息。行动。您的选择必须基于预期的有效负载大小。来自 MSDN
A raw notification is probably best used alongside a pull request in a lot of cases. I would tend to use a notification purely to tell a running client that - that could be anything from a new message has arrived server-side (in which case you might want to send out the message in the notification) to "The whole of the data set on the server has been updated, you'd better come along when you can and get the latest changes".
As mentioned, you can use the raw notification to send out all the required information if it is small enough, but on other occasions you will most likely just be telling the app that it needs to call home for some action. Your choice would have to be based on the expected size of the payload. From MSDN
