red5-websocket
Websocket plug-in for Red5
This plugin is meant to provide websocket functionality for applications running in red5. The code is constructed to comply with rfc6455.
http://tools.ietf.org/html/rfc6455
Special thanks to Takahiko Toda and Dhruv Chopra for the initial ideas and source.
Configuration
Add the WebSocket transport to the jee-container.xml or red5.xml. If placing it in the red5.xml, ensure the bean comes after the plugin launcher entry.
To bind to one or many IP addresses and ports:
<bean id="webSocketTransport" class="org.red5.net.websocket.WebSocketTransport">
<property name="addresses">
<list>
<value>192.168.1.174</value>
<value>192.168.1.174:8080</value>
<value>192.168.1.174:10080</value>
</list>
</property>
</bean>
If you don't want to specify the IP:
<bean id="webSocketTransport" class="org.red5.net.websocket.WebSocketTransport">
<property name="port" value="8080"/>
</bean>
To support secure communication (wss) add this:
<bean id="webSocketTransportSecure" class="org.red5.net.websocket.WebSocketTransport">
<property name="secureConfig">
<bean id="webSocketSecureConfig" class="org.red5.net.websocket.SecureWebSocketConfiguration">
<property name="keystoreType" value="JKS"/>
<property name="keystoreFile" value="conf/keystore"/>
<property name="keystorePassword" value="password"/>
<property name="truststoreFile" value="conf/truststore"/>
<property name="truststorePassword" value="password"/>
</bean>
</property>
<property name="addresses">
<list>
<value>192.168.1.174:10081</value>
</list>
</property>
</bean>
Adding WebSocket to an Application
To enable websocket support in your application, add this to your appStart() method:
WebSocketScopeManager manager = ((WebSocketPlugin) PluginRegistry.getPlugin("WebSocketPlugin")).getManager();
manager.addApplication(scope);
For clean-up add this to appStop():
WebSocketScopeManager manager = ((WebSocketPlugin) PluginRegistry.getPlugin("WebSocketPlugin")).getManager();
manager.removeApplication(scope);
Test Page
Replace the wsUri variable with your applications path.
<!DOCTYPE html>
<meta charset="utf-8" />
<title>WebSocket Test</title>
<script language="javascript" type="text/javascript">
var wsUri = "ws://192.168.1.174:10080/myapp";
var output; function init() { output = document.getElementById("output"); testWebSocket(); } function testWebSocket() { websocket = new WebSocket(wsUri); websocket.onopen = function(evt) { onOpen(evt) }; websocket.onclose = function(evt) { onClose(evt) }; websocket.onmessage = function(evt) { onMessage(evt) }; websocket.onerror = function(evt) { onError(evt) }; } function onOpen(evt) { writeToScreen("CONNECTED"); doSend("WebSocket rocks"); } function onClose(evt) { writeToScreen("DISCONNECTED"); } function onMessage(evt) { writeToScreen('<span style="color: blue;">RESPONSE: ' + evt.data+'</span>'); websocket.close(); } function onError(evt) { writeToScreen('<span style="color: red;">ERROR:</span> ' + evt.data); } function doSend(message) { writeToScreen("SENT: " + message); websocket.send(message); } function writeToScreen(message) { var pre = document.createElement("p"); pre.style.wordWrap = "break-word"; pre.innerHTML = message; output.appendChild(pre); } window.addEventListener("load", init, false); </script> <h2>WebSocket Test</h2> <div id="output"></div>
