在Ionic/Cordova应用程序中,如何确保在应用程序关闭时触发onNotificationOpen回调?

我很难弄清楚为什么iOS应用程序在关闭或终止时无法注册推送通知的点击。它在前台模式下工作得很好,后台模式下只要应用程序没有被杀死。

当应用程序“死掉”时 onNotificationOpen 回调从未被触发,因此我无法将用户路由到应用程序中所需的位置。

有人能指出我的错误,或者给我一个有效的例子吗?文件 cordova-plugin-firebase 对于推送通知非常少。

应用组件

this.platform.ready().then(() => {
   if (this.platform.is('cordova')) {
      this.pushProvider.init();

      this.platform.resume.subscribe(() => {
         this.pushProvider.init();
      });
   }
});

推送提供商

import { Injectable } from '@angular/core';
import { Firebase }   from '@ionic-native/firebase';
import { Platform }   from 'ionic-angular';

@Injectable()
export class PushNotificationsProvider {
    constructor (private firebase: Firebase, private platform: Platform) {
    }

    init () {
        if (!this.platform.is('cordova')) {
            return;
        }

        if (this.platform.is('ios')) {
            this.firebase.grantPermission().then(() => {
                this.initListeners();
            });
        } else if (this.platform.is('android')) {
            this.firebase.hasPermission().then(data => {
                if (data && data.isEnabled) {
                    this.initListeners();
                }
            });
        }
    }

    initListeners () {
        this.firebase.onNotificationOpen().subscribe((notification: any) => {
            this.handleNotification(notification);
        });
    }

    handleNotification (notification) {
        if (!notification) {
            return;
        }

        if (notification.tap) {
            this.backgroundNotification(notification);
        } else {
            this.foregroundNotification(notification);
        }
    }

    backgroundNotification (notification) {
        const message = (notification.aps || {}).alert;
        alert('*** FMC: opened in background: ' + message);
    }

    foregroundNotification (notification) {
        const message = (notification.aps || {}).alert;
        alert('*** FMC: opened in foreground: ' + message);
    }
}
