我知道Firebase云消息传递方便发送推送通知和数据消息。我正在使用Flutter的firebase_messaging pub接收设备中的通知。onMessage、onLaunch和onResume回调只有在通知被取消或单击后才会被调用。
但是，我想访问收到的消息，无论通知是否被驳回。有没有办法做到这一点，不管app是在前台、后台还是被终止？
您可以立即将您的消息发送到广播接收器，并在此解析它
更新：
您应该创建broadcastreceiver:
class YourBroadcastReceiver : BroadcastReceiver() {
override fun onReceive(context: Context?, intent: Intent?) {
//some code..
}
}
然后在清单中注册：
<receiver
android:name="com.yourApp.YourBroadcastReceiver"
android:enabled="true"
android:exported="true">
<intent-filter>
<action android:name="YourBroadcastReceiver " />
</intent-filter>
</receiver>
下一个也是最后一个步骤是在FireBaseMessagingService方法OnMessageReceived中，您可以获取ur数据并将其发送到YourBroadcastReceiver:
override fun onMessageReceived(remoteMessage: RemoteMessage) {
super.onMessageReceived(remoteMessage)
val messageText = remoteMessage.data[yourData]
val intent = Intent(this, YourBroadcastReceiver ::class.java)
intent.putExtra(messageText, messageText)
sendBroadcast(intent)
}
