我可以发送推送通知，在服务工作器中进行服务调用，我只想在该服务调用中发送GCM注册ID。如何在服务工作器中获取注册ID或订阅ID？
这是我的代码：
这是我的代码：
self.addEventListener('push', function(event) {
console.log('Received a push message from local', event);
var title = 'My title file. Testing on';
var body = 'New Push Message.';
var icon = 'refresh_blueicon.png';
var tag = 'my-push-tag';
event.waitUntil(
// Here i need to wind GCM Registration id / Subscription id with external service call
fetch('http://localhost/pushMsg/Push_Notification/msg.php').then(function(response){
if (response.status !== 200) {
console.log('Looks like there was a problem. Status Code: ' +
response.status);
throw new Error();
}
// Examine the text in the response
return response.json().then(function(data) {
self.registration.showNotification(data.title, {
body: data.msg,
icon: icon,
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('/');
}));
});
