【中文标题】如何修复应用休眠 1 分钟后未收到 Firebase FCM 的通知【英文标题】：How to fix notification Firebase FCM not recieved after app sleeping 1 min 【发布时间】：2021-12-12 00:49:04 【问题描述】：我的应用程序约会有问题，我使用功能云 Firebase 发送通知，但在 1 分钟睡眠应用程序后未收到通知，就在我单击按钮以打开手机收到通知时，我看到应用程序何时连接始终显示有线 USB 通知。 这个笔记我认为是电池。所以如果有人有任何想法，我将在下面分享我的代码谢谢

使用 Node.js index.js 的函数：
if(notification_state=="message")
const payload =
data:
title : `$username`,
body : `$last_message`,
userIDvisited : from_user_id,
state_app:state_app,
notification_state:notification_state,
priority:"high"
;
return admin.messaging().sendToDevice(token_id,payload).then(response =>
console.log('this was the notification Feature ');
);
【问题讨论】：
【参考方案1】：查看Google Firebase Cloud Messaging，我找到了Handle notification messages in a background app和Background restricted app的解决方案。
在后台应用中处理通知消息：
当您的应用处于后台时，Android 会将通知消息定向到系统托盘。默认情况下，用户点击通知会打开应用启动器。 这包括同时包含通知和数据负载的消息（以及从通知控制台发送的所有消息）。
在这些情况下，通知会传递到设备的系统托盘，而数据负载会在启动器 Activity 的意图的附加部分中传递。
后台受限应用：
FCM 可能不会向用户放入background restriction 的应用传递消息（例如通过：设置 -> 应用和通知 -> [应用名称] -> 电池）。一旦您的应用程序从后台限制中删除，新消息将像以前一样传递到该应用程序。为防止消息丢失和其他背景限制影响，请务必避免 Android vitals 努力列出的不良行为。
解决方案：
我已将 Google Play 服务从电池优化中列入白名单，因此它永远不会死机，并以编程方式调整 WIFI 设置，即使在深度睡眠时也能运行。现在，即使处于睡眠模式，手表也会收到通知。
