I successfully send the notification to google chrome. My service-worker.js is below.
'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'
;
event.waitUntil(
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: http://crbug.com/463146
event.notification.close();
// This looks to see if the current is already open and
// focuses if it is
event.waitUntil(clients.matchAll({
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.

tRequest.Headers.Add(
String
.Format(
"Authorization: key={0}"
, SERVER_API_KEY))
tRequest.Headers.Add(

, SENDER_ID))
Dim

""
Console.WriteLine(postData)
Dim
byteArray
As
[
Byte
]() = Encoding.UTF8.GetBytes(postData)
tRequest.ContentLength = byteArray.Length
Dim
dataStream
As
Stream = tRequest.GetRequestStream()
dataStream.Write(byteArray, 0, byteArray.Length)
dataStream.Close()
Dim

dataStream = tResponse.GetResponseStream()
Dim
