离子本地通知错误：未捕获（在承诺中）：TypeError：对象（...）不是函数

Question

我想在我的离子项目中添加本地通知。我在app.module.ts中添加;

从'@ ionic-native / local-notifications / ngx'导入{LocalNotifications};

我在提供商中添加了LocalNotifications。

也在home.ts我写这个代码;

sendLocalNotifications() {

this.localNotifications.schedule({
  title: 'Local ILocalNotification Example',
  text: 'Delayed ILocalNotification',
  trigger: {at: new Date(new Date().getTime() + 3600)},
  led: 'FF0000',
  data: {secret: "asaddad"},

  sound: null
});

我也在home.ts中做了import和constructor的定义。当我在android设备上运行我的代码时出现以下错误;

**Error: Uncaught (in promise): TypeError: Object(...) is not a function
TypeError: Object(...) is not a function
    at LocalNotifications.schedule (vendor.js:92805)

    at t.invokeTask (polyfills.js:3)
    at r.runTask (polyfills.js:3)
    at o (polyfills.js:3)**

你能帮助我吗？

如果您使用离子3，请访问此链接

https://ionicframework.com/docs/v3/native/local-notifications/

安装cordova插件＆npm

$ ionic cordova plugin add cordova-plugin-local-notification
$ npm install --save @ionic-native/local-notifications@4

需要在app.module.ts文件中导入

import {LocalNotifications} from '@ionic-native/local-notifications';

在providers数组[app.module.ts文件]中添加LocalNotifications

 providers: [
            StatusBar,
            SplashScreen,
            ImagePicker,
            InAppBrowser,
            LoginService,
            ConnectivityService,
            Network,
            GooglePlus,
            GoogleServiceProvider,
            GoogleMapsKeyProvider,
            AppVersion,
            BarcodeScanner,
            Device,
            FCM,
            CheckStorageProvider,
            Facebook,
            Geolocation,
            TwitterConnect,
            LinkedIn,
            File,
            Camera,
            FileTransfer,
            FilePath,
            Base64,
            {provide: ErrorHandler, useClass: IonicErrorHandler},
            LocalNotifications
        ]


this.localNotifications.requestPermission().then((permission) => {
            this.localNotifications.schedule({
                id: 0,
                text: 'Delayed ILocalNotification',
                trigger: {at: date},
                foreground: true,
                vibrate: true,
                led: {color: '#FF00FF', on: 500, off: 500},
                data: {mydata: 'My hidden message this is'},
                sound: this.setSound(),
            });
        });

通过将.mp3声音文件放在src / assets / sounds / sound.mp3来设置声音

setSound() {
        if (this.platform.is('android')) {
            return 'file://assets/sounds/sound.mp3'
        } else {
            return 'file://assets/sounds/sound.mp3'
        }
    }

您可以在使用订阅方法收到通知后阅读隐藏的消息（可以在主页或app.component.ts文件中添加）

if (_platform.is('cordova')) {
            this.localNotifications.on('click').subscribe((datas: any) => {
                    alert(JSON.stringify(datas));
                });
        }
