在Firebase中以编程方式实现Android通知

在没有后端的android中发送通知，我们必须在android studio中编写以下代码行：

NotificationManager manager = (NotificationManager) getSystemService(NOTIFICATION_SERVICE);

Intent intentViewPost = new Intent(PostsActivity.this,BlogPostsView.class);
PendingIntent pendingIntent = PendingIntent.getActivity(PostsActivity.this,(int) System.currentTimeMillis(), intentViewPost,0);

Notification notification = new Notification.Builder(getBaseContext())
        .setSmallIcon(R.mipmap.ic_app_logo)
        .setContentTitle(getResources().getString(R.string.app_name))
        .setContentText(postTitle)
        .setContentIntent(pendingIntent)
        .build();

manager.notify(111,notification);

如果不使用控制台，如何在Firebase中执行相同的操作。

向特定设备发送消息

要向特定设备发送消息，请将设置为特定应用程序实例的注册令牌

curl -H "Content-type: application/json" -H "Authorization:key=<Your Api key>"  -X POST -d '{ "data": { "score": "5x1","time": "15:10"},"to" : "<registration token>"}' https://fcm.googleapis.com/fcm/send

curl-H”内容类型：application/json“-H”授权：key=“-X POST-d'{“data”：{“score”：“5x1”，“time”：“15:10”}，to”：“}”https://fcm.googleapis.com/fcm/send

向主题发送消息

这里的主题是：/topics/foo-bar

curl -H "Content-type: application/json" -H "Authorization:key=<Your Api key>"  -X POST -d '{ "to": "/topics/foo-bar","data": { "message": "This is a Firebase Cloud Messaging Topic Message!"}}' https://fcm.googleapis.com/fcm/send

curl-H“Content-type:application/json“-H”Authorization:key=“-X POST-d'{“to”：“/topics/foo bar”，“data”：{“message”：“这是Firebase云消息主题消息！”}”https://fcm.googleapis.com/fcm/send

向设备组发送消息

向设备组发送消息与向单个设备发送消息非常相似。将to参数设置为设备组的唯一通知密钥

curl -H "Content-type: application/json" -H "Authorization:key=<Your Api key>"  -X POST -d '{"to": "<aUniqueKey>","data": {"hello": "This is a Firebase Cloud Messaging Device Group Message!"}}' https://fcm.googleapis.com/fcm/send

curl-H”内容类型：application/json“-H”授权：key=“-X POST-d'{“to”：


这并不能回答我的问题
