Openfire Push Server Plugin

An XEP-0357: Push Notifications app server that relays push messages between the user’s server and FCM (Firebase Cloud Messaging) or APNS (Apple Push Notification Service).

Building

This project is using the Maven-based Openfire build process, as introduced in Openfire 4.2.0. To build this plugin locally, ensure that the following are available on your local host:

A Java Development Kit, version 7 or (preferably) 8
Apache Maven 3

To build this project, invoke on a command shell:

$ mvn clean package

Upon completion, the openfire plugin will be available in target/pushserver-openfire-plugin-assembly.jar. This file should be renamed to pushserver.jar

Installation

Copy pushserver.jar into the plugins directory of your Openfire server, or use the Openfire Admin Console to upload the plugin. The plugin will then be automatically deployed.

To upgrade to a new version, copy the new pushserver.jar file over the existing file.

After installing plugin, you should fill the fields under the page `Server -> Server Settings -> Push Server Properties.

Note: After filling and saving values, you should restart the plugin.

Enabling Notifications

After registering with the push server, Client sends the node ID and the jid of the app server (push.example.com) to the user's server.

<iq type='set' id='x42'>
  <enable xmlns='urn:xmpp:push:0' jid='push.example.com' node='KmDtdKoUTiGr'>
    <x xmlns='jabber:x:data' type='submit'>
      <field var='FORM_TYPE'><value>http://jabber.org/protocol/pubsub#publish-options</value></field>
      <field var='secret'><value>FBfIl4qflMTDKn6CYPxXJHyH</value></field>
    </x>
  </enable>
</iq>

Note: To support sandbox devices in iOS, you should provide the <field var="sandbox"><value>true</value></field> in publish options.

Example:

<iq type='set' id='x42'>
  <enable xmlns='urn:xmpp:push:0' jid='push.example.com' node='37Ni514izxHG'>
    <x xmlns='jabber:x:data' type='submit'>
      <field var='FORM_TYPE'><value>http://jabber.org/protocol/pubsub#publish-options</value></field>
      <field var='secret'><value>Zt9z9wOtAUOSYCtYC7a5OORa</value></field>
