React Native-在Android中无法访问前台Firebase推送通知

Question

async createNotificationListeners() {
  /*
   * Triggered when a particular notification has been received in foreground
   * */
  this.notificationListener = firebase
    .notifications()
    .onNotification(notification => {
      console.log("fg", notification);
      const { title, body } = notification;
      this.showAlert(title, body);
    });

  /*
   * If app is in background, listen for when a notification is clicked / tapped / opened as follows:
   * */
  this.notificationOpenedListener = firebase
    .notifications()
    .onNotificationOpened(notificationOpen => {
      console.log("bg", notificationOpen);
      const { title, body } = notificationOpen.notification;
      this.showAlert(title, body);
    });

  /*
   * If app is closed, check if it was opened by a notification being clicked / tapped / opened as follows:
   * */
  const notificationOpen = await firebase
    .notifications()
    .getInitialNotification();
  if (notificationOpen) {
    console.log("bg", notificationOpen);
    const { title, body } = notificationOpen.notification;
    this.showAlert(title, body);
  }
  /*
   * Triggered for data only payload in foreground
   * */
  this.messageListener = firebase.messaging().onMessage(message => {
    //process data message
    console.log("fg", JSON.stringify(message));
  });
}

这里，根本不会触发firebase.notifications().onnotification或firebase.messaging().onmessage()。

在其他的解决方案，这是因为从Android8你需要创建一个通道，但我找不到任何选项创建通道，同时发送通知从FCM通知作曲者。

阿卜杜勒,

您需要在设备上使用firebase创建通知通道。

const channel = new firebase.notifications.Android
  .Channel('default', 'Default Channel', firebase.notifications.Android.Importance.Max)
  .setDescription('The default notification channel.')

firebase.notifications().android.createChannel(channel)

这将创建通道，您可以调用它的次数，因为您想要安全（根据文档）。您的onNotification监听器看起来很好，您只需要在进入的通知上设置android通道。

  notification.android.setChannelId('default')
