PushManager.subscribe()

Перевод не завершен. Пожалуйста, помогите перевести эту статью с английского.

This is an experimental technology
Because this technology's specification has not stabilized, check the compatibility table for the proper prefixes to use in various browsers. Also note that the syntax and behavior of an experimental technology is subject to change in future versions of browsers as the spec changes.

The subscribe() method of the PushManager interface subscribes to a push service.

It returns a Promise that resolves to a PushSubscription object containing details of a new push subscription.

Syntax

​PushManager.subscribe(options).then(function(pushSubscription) { ... } );

Parameters

options Необязательный
An object containing optional configuration parameters. It can have the following properties:
  • userVisibleOnly: A boolean indicating that the returned push subscription will only be used for messages whose effect is made visible to the user.

Returns

A Promise that resolves to a PushSubscription object.

Example

this.onpush = function(event) {
  console.log(event.data);
  // From here we can write the data to IndexedDB, send it to any open
  // windows, display a notification, etc.
}

navigator.serviceWorker.register('serviceworker.js').then(
  function(serviceWorkerRegistration) {
    serviceWorkerRegistration.pushManager.subscribe().then(
      function(pushSubscription) {
        console.log(pushSubscription.subscriptionId);
        console.log(pushSubscription.endpoint);
        // The push subscription details needed by the application
        // server are now available, and can be sent to it using,
        // for example, an XMLHttpRequest.
      }, function(error) {
        // During development it often helps to log errors to the
        // console. In a production environment it might make sense to
        // also report information about errors back to the
        // application server.
        console.log(error);
      }
    );
  });
