React Native-无法在Android中访问前台的Firebase推送通知

React Native: Integrating Push Notifications using FCM

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));
  });
}

在这里 firebase.notifications().onNotification 或 firebase.messaging().onMessage()

在其他解决方案中,这是因为在Android 8中,您需要创建一个频道,但在从FCM发送通知时,我找不到任何创建频道的选项 notification composer .
