XmppPlugin.php |
XMPP (eXtended Message and Presence Protocol, <http://xmpp.org/>) is the federating instant-messaging protocol of the future. It is wildly used all over the world by organisations, private individuals and everyone. GNU social allows you to receive and distribute messages via XMPP using this plugin. To get it running, you must also use an active XMPP account. Installation ============ Add an addPlugin call to your config.php with your settings. Please read the "Pre-requisites" section of what is required for this to work. Example ------- The example account "update@site.example" is hosted on a machine which can be reached at the hostname "xmpp.site.example". addPlugin('Xmpp', array( 'user' => 'update', 'server' => 'site.example', 'host' => 'xmpp.site.example', 'password' => '...', )); Pre-requisites ============== 0. You may want to strongly consider setting up your own XMPP server. We highly recommend the XMPP server "Prosody" <https://prosody.im/> because it is actively developed and highly secure and efficient. It is of course also free software under the MIT license. The following three pages will help you get it running, even self-hosted at home: 0.1 https://prosody.im/doc/dns 0.2 https://prosody.im/doc/install 0.3 https://prosody.im/doc/configure 1. You must register an XMPP user ID (JID) which is used to send and receive messages. Call it something like "update@site.example" or similar to hint at what the account is made for. You may register the account on any public server (jabber.org, jit.si, etc...) if you cannot run one yourself. GNU social will not register anything for you, this must be done manually, preferrably using an XMPP client like Swift, Empathy, Jitsi or maybe even the commandline on your own server. With prosody, that'd be (perhaps prepended with 'sudo'): prosodyctl adduser update@site.example 2. Configure your site's XMPP variables, as described below in the Settings section below. 3. Learn to use the GNU social daemons for processing notice queues, background checks and other processes which would be too slow to perform on an active site. Using XMPP requires the "imdaemon" to run, since a long-running XMPP connection is somewhat necessary. A design goal of GNU Social is that the basic Web functionality should work on even the most restrictive commercial hosting services. However, additional functionality, such as receiving messages by XMPP, require that you be able to run long-running processes on your account. Settings ======== Required -------- user User part of the jid (like 'update') server Host part of the jid (like 'site.example') password The account's password. (your secret string) Optional -------- resource JID resource. Default: 'gnusocial' encryption TLS server? Default: true host Hostname for XMPP server? Default: same as server port XMPP server port. Default: 5222 debug Log extra debug info. Default: false public JIDs that should get the public feed (see "Public feed"). Since we do not currently support DNS SRV record lookup, please note that you may have to enter an alternative 'host' parameter. This is the case when update@site.example is not handled by the direct _address_ "site.example" but rather something like "xmpp.site.example". Public feed =========== You can send *all* messages from your social networking site to a third-party service using XMPP. This can be useful for providing search, indexing, bridging, or other cool services. Maybe a text display next to your coffee machine at work. To configure a downstream site to receive your public stream, add their "JID" (Jabber ID) in the "public" array in your addPlugin call. For example addPlugin(array( [...] 'public' => array('awesomebot@site.example'), As the Pre-requisites section says, please only try to configure this with daemons running properly in the background.
