ÎonicLocalNotification：使用日期匹配触发器时，我反复收到通知

Question

我正在使用ionic-native的LocalNotifications每次下午6点触发本地通知。但是，当下午6点时，我会收到大量垃圾邮件通知。 我只想在下午6点接收一个通知，而不是每次下午6点接收。

import { Component, OnInit } from '@angular/core';
import { Router } from '@angular/router';
import { Platform, AlertController } from '@ionic/angular';
import { LocalNotifications } from '@ionic-native/local-notifications/ngx';

@Component({
  selector: 'app-mypage',
  templateUrl: './mypage.page.html',
  styleUrls: ['./mypage.page.scss'],
})
export class MyPagePage implements OnInit {

  constructor(private router: Router, private plt: Platform, private localNotifications: LocalNotifications, private alertCtrl: AlertController) {
    this.initPlatform();
  }

  ngOnInit() {

  }

  private initPlatform() {
    this.plt.ready().then(() => {
      this.localNotifications.on('click').subscribe(res => {
        let msg = res.data ? res.data.mydata : '';
        this.showAlert(res.title, res.text, msg);
      });

      this.localNotifications.on('trigger').subscribe(res => {
        let msg = res.data ? res.data.mydata : '';
        this.showAlert(res.title, res.text, msg);
      });
    });
    this.scheduleNotification();
  }

  private scheduleNotification() {
    this.localNotifications.schedule({
      id: 1,
      title: 'Session terminée',
      text: 'Donnez votre avis',
      data: { mydata: 'Donnez votre avis' },
      trigger: { every: { hour: 18, minute: 0 } },
      foreground: true
    });
  }

  private showAlert(header, sub, msg) {
    this.alertCtrl.create({
      header: header,
      subHeader: sub,
      message: msg,
      buttons: ['Ok']
    }).then(alert => alert.present());
  }
}
