推荐答案

当你发送通知，你可以设置的优先级参数为高。

When sending your notification you could set the priority-parameter to "high".

从文档：

在默认情况下，消息发送正常优先级。 普通优先级优化了客户端应用程序的电池消耗，应该使用，除非立即交货是必需的。对于正常优先级的消息，该应用程序可能会收到消息未指定的延迟。

By default, messages are sent with normal priority. Normal priority optimizes the client app's battery consumption, and should be used unless immediate delivery is required. For messages with normal priority, the app may receive the message with unspecified delay.

当邮件发送是高优先级，它立即发送，然后应用程序可以唤醒一个沉睡的设备，并打开网络连接到服务器。

When a message is sent with high priority, it is sent immediately, and the app can wake a sleeping device and open a network connection to your server.

我知道这个答案来晚了，不过如果你仍然面临这个问题（或其他人），请告诉我，如果它帮助。
