谷歌云消息- GCM注册id在服务工作者在chrome的推送通知

Question

我能够发送推送通知，并且在service worker中我正在进行服务调用，我只是想用该服务调用发送GCM注册id。如何在service worker中获取注册id或订阅id

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('/');
  }));
});

如果您已经订阅了用户，那么您应该已经在pushManager对象上拥有可用的订阅。所以像这样的代码应该可以工作:

registration.pushManager.getSubscription().then(function(subscription) {
  console.log("got subscription id: ", subscription.endpoint)
});

这是整个端点，如果你只想要id你可以这样写:

subscription.endpoint.split("/").slice(-1))
