RNFirebase v6推送通知不会同时出现在两个iOS上

Question

我正在尝试将通知从firebase控制台发送到我的react本机应用程序

据我所知，我遵循了这里糟糕的文档：https://invertase.io/oss/react-native-firebase/v6/messaging/quick-start

我安装了@react native firebase/app和/messaging，下面是我在组件中的代码：

  componentDidMount() {

    this.reqNotifications()
    this.checkNotificationPermission()

  }


  reqNotifications() {

    requestNotifications(['alert', 'badge', 'sound']).then(({status, settings}) => {

      console.log('NOTIFICATION STATUS' + status)

    });

  }

  async checkNotificationPermission() {
    const enabled =  await messaging().hasPermission();
    if (enabled) {
      console.log('APPROVED');
      await messaging().registerForRemoteNotifications()
      messaging().getToken().then(token => console.log('token: >> ' + token))



    } else {
      console.log('NOT APPROVED');
    }
  }

• 我正在通过react native permissions请求权限，权限请求正在运行

但我无法从firebase向设备发送任何信息；前景和背景都没有发生任何事情。我尝试了令牌测试，也尝试了正常测试，但没有，什么都没有发生。

我在componentDidMount中添加了以下代码：

messaging().onMessage(async remoteMessage => {
  console.log('FCM Message Data:', remoteMessage.data);
});

据我所知，这是订阅云消息，当我从firebase控制台发送一些云消息通知时，我应该得到控制台输出；但什么都没发生。

我不知道我错过了什么，但我认为这个软件包有一个大的更新，大多数文档都是以前的版本，我真的停留在这里感谢您的帮助

for rnfirebase.io V6
 componentDidMount = async () => {
    this.checkNotificationPermission();
    await messaging().requestPermission({provisional: true});
    await messaging().registerDeviceForRemoteMessages();

    await this.getFCMToken();
    if (Platform.OS === 'android') {
      this.createAndroidNotificationChannel();
    }

    this.backgroundState();
    this.foregroundState();
  };   
checkNotificationPermission = () => {
    firebase
      .messaging()
      .hasPermission()
      .then(enabled => {
        if (!enabled) {
          this.promptForNotificationPermission();
        }
      });
  };

  promptForNotificationPermission = () => {
    firebase
      .messaging()
      .requestPermission({provisional: true})
      .then(() => {
        console.log('Permission granted.');
      })
      .catch(() => {
        console.log('Permission rejected.');
      });
  };

  createAndroidNotificationChannel() {
    const channel = new firebase.notifications.Android.Channel(
      'channelId',
      'Push Notification',
      firebase.notifications.Android.Importance.Max,
    ).setDescription('Turn on to receive push notification');

    firebase.notifications().android.createChannel(channel);
  }
 foregroundState = () => {
    const unsubscribe = messaging().onMessage(async notification => {
      console.log('Message handled in the foregroundState!', notification);
    });

    return unsubscribe;
  };

  // Register background handler
  backgroundState = () => {
    messaging().setBackgroundMessageHandler(async notification => {
      console.log('Message handled in the background!', notification);
    });
  };
