android - Firebase 云消息传递 : Parsing data from the message even when the app is terminated

Question

我了解 Firebase Cloud Messaging 有助于发送推送通知和数据消息。我正在使用 Flutter 的 firebase_messaging pub 在我的设备中接收通知。 onMessage、onLaunch 和 onResume 回调仅在关闭或单击通知时调用。

但是，无论通知是否被取消，我都想访问收到的消息。有没有办法做到这一点，无论应用程序是在前台、后台还是已终止？

您可以立即将您的消息发送到广播接收器并在此处解析它

更新:

您应该创建 BroadcastReceiver:

class YourBroadcastReceiver : BroadcastReceiver() {

    override fun onReceive(context: Context?, intent: Intent?) {
        //some code..
    }
}

然后在 Manifest 中注册它:

<receiver
    android:name="com.yourApp.YourBroadcastReceiver"
    android:enabled="true"
    android:exported="true">
    <intent-filter>
        <action android:name="YourBroadcastReceiver " />
    </intent-filter>
</receiver>

下一步也是最后一步是在 FirebaseMessagingService 方法 onMessageReceived 中，您可以获取数据并将其发送到 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)
}
