strophe-openfire-websocket

Use strophe to connect nginx or haproxy websocket proxy

Recommand using haproxy as websocket proxy because "Connection reset by peer" happens in nginx and then connection become unavailiable, especially lots of concurrent connections or large data transfer

Especially thanks to Dele Olajide for developing the project (https://code.google.com/p/openfire-websockets/)

Installation

####Server Side (openfire):

• If you use Openfire 3.10, download websockets.war (I rebuild the plugin source within openfire 3.10 source) here and put it to your openfire plugin directory
• If you use Openfire 3.9.3, download websocket plugin (websockets-0.0.0.6.zip, https://code.google.com/p/openfire-websockets/downloads/list) and unzip file to your openfire plugin directory
• Restart openfire server (When you use websockets.war, you have to check whether websocket.jar and Websocket.jar coexist in plugin directory. If it happens, delete Websocket.jar and restart openfire to ensure openfire load correct jar)
• Visit openfire admin site and select the tab "Server" and you should see the child tab "WebSockets" and the default "Web Application Name" is ws

####Server Side (nginx): Note: if you want to connect openfire directly, just skip this step

• Checkout strophe-openfire-websocket.js and include strophe-openfire-websocket.js to your html
• Add the code below to your js

    var arrURL = document.URL.split('/'),
        protocol = (arrURL[0] === 'http:' ? 'ws://' : 'wss://'),
        wsUrl = protocol + arrURL[2] + '/xmpp-websocket';

    var conn = new Openfire.Connection(wsUrl);
