I sucessfully send notification to google chrome. My service-worker.js is below.

What my question is When i'm sending with above code the push up notification showing whatever in the Hard coded title and body which is in service-worker.js. How to show my message which is in above .net code.

Thanks Basit.

What I have tried:

My service-worker.js is below.

<pre lang="Javascript"><pre lang="Javascript">
'use strict';

self.addEventListener('push', function(event) {
console.log('Received a push message', event);

var title = 'Pushup Notification';
var body = 'Test';
var icon = 'images/icon.png';
var badge = 'images/badge.png'
var tag = 'simple-push-demo-notification-tag';

self.registration.showNotification(title, {
body: body,
icon: icon,
badge: badge,
tag: tag

self.addEventListener('notificationclick', function(event) {
console.log('On notification click: ', event.notification.tag);
// Android doesn’t close the notification when you click on it
// See:

// This looks to see if the current is already open and
// focuses if it is
type: 'window'
}).then(function(clientList) {
for (var i = 0; i < clientList.length; i++) {
var client = clientList[i];
if (client.url === '/' && 'focus' in client) {
return client.focus();
if (clients.openWindow) {
return clients.openWindow('/');
Below is the sending code to Google Chrome.

Public Function SendNotification(ByVal deviceId As String, ByVal message As String) As String

        Dim SERVER_API_KEY As String = "API KEY"
        Dim SENDER_ID = "Sender ID"
        Dim value = message
        Dim tRequest As WebRequest
        tRequest = WebRequest.Create("")
        tRequest.Method = "post"
        tRequest.ContentType = " application/x-www-form-urlencoded;charset=UTF-8"
        tRequest.Headers.Add(String.Format("Authorization: key={0}", SERVER_API_KEY))

        tRequest.Headers.Add(String.Format("Sender: id={0}", SENDER_ID))

        Dim postData As String = (Convert.ToString((Convert.ToString("collapse_key=score_update&time_to_live=108&delay_while_idle=1&data.message=") & value) + "&data.time=" + System.DateTime.Now.ToString() + "®istration_id=") & deviceId) + ""
        Dim byteArray As [Byte]() = Encoding.UTF8.GetBytes(postData)
        tRequest.ContentLength = byteArray.Length

        Dim dataStream As Stream = tRequest.GetRequestStream()
        dataStream.Write(byteArray, 0, byteArray.Length)

        Dim tResponse As WebResponse = tRequest.GetResponse()

        dataStream = tResponse.GetResponseStream()

        Dim tReader As New StreamReader(dataStream)

        Dim sResponseFromServer As [String] = tReader.ReadToEnd()

        Return sResponseFromServer

    End Function
