如何在Cordova应用程序中使用推送通知？

Question

I have some strange problem... I'm using push notifications for messaging in my Ionic app but it works from time to time... My code is:

public initPushNotification() {
    if (!this.platform.is('cordova')) {
        console.warn('Cordova is not available - Run in physical device. Push notifications not initialized.');

        return;
    }

    let zone = new NgZone({ enableLongStackTrace: false });

    zone.run(() => {
        this.Push.hasPermission().then((res: any) => {
            if (res.isEnabled) {
                const options: PushOptions = {
                    android: {
                        senderID: GOOGLE_FCM_ID
                    }
                };

                let push_object = this.Push.init(options);

                push_object.on('registration').subscribe((data: any) => {
                    this.APIRequest.post('/messages/register-fcm-token', data).subscribe(response => {
                        console.log(response)
                    }, err => {
                        console.log(err)
                    })

                    console.log('push.registration', data);
                });

                push_object.on('notification').subscribe((data: any) => {
                    console.log('push.notification', data);

                    this.events.publish('messages:push', data.message);
                });

                push_object.on('error').subscribe(error => console.error('Error with Push plugin', error));
            } else {
                alert('We do not have permission to send push notifications');
            }
        });
    });
}

It is located in app.component.ts .

Some of behavior:

1. Works fine when app is minimized on Cat S60 phone
2. Some times works when app is minimized on some cheap Huawei
3. Some time works on both devices when app is opened as it should be. In most times not.

When I send it to Google I receive back OK status.

You can use one signal for notifications. It's fast and effective. You can get detailed information from the links below.
