Overview
This feature allows to have unlimited set of connections initiated from aiengine server to external servers.
Implementation Details
- aiengine creates all active sockets on startup
- active socket is available via AIMedia interface
- active socket is available via IO channels if configured
- inbound stream can be forwarded to configured IO channel
- stream from specific IO channel can be forwarded to outbound
- active socket supports protocol configuring - see Protocols
- if forwarding inbound stream - creates thread to read from socket and automatically reconnects if connection was broken
Planned but implemented:
- to have non-persisting connections - to use active connection only after request from server, do not restore connection automatically
- timeout for reconnection
Configuration
- sample configuration for google active socket in media.xml
<channel name="google" run="true"> <property name="protocol" value="http"/> <property name="protocol.showmessages" value="false"/> <property name="protocol.showpackets" value="false"/> <property name="msgtype" value="text"/> <property name="permanent" value="true"/> <property name="host" value="www.google.com"/> <property name="port" value="80"/> <property name="redirect-in" value="true"/> <property name="redirect-out" value="true"/> <property name="topic-in" value="http.response"/> <property name="topic-out" value="http.request"/> </channel>
- *host* - host to connect to - now IP-addresses are not supported
- *port* - port to connect to
- *redirect-in* - if "true" then messages are forwarded from socket to IO channel
- *redirect-out* - if "true" then messages are forwarded from IO channel to socket
- *topic-in* - channel to write messages received from socket
- *topic-out* - messages from this channel are sent to socket - see Protocols
- *reconnectionTimeout* - if unable to connect to socket, then next attempt is performed only after reconnectionTimeout seconds
How to Test
- use google active socket and test to read some page:
INFO: AI console
INFO: connected to 87.228.126.111:20001
REQUEST:
<xmlcall name="TestDirectChannels-Google" class="TestDirectChannels" method="testRequestPage" requestId="REQ-1">
<parameters>
<property name="page" value="http://code.google.com" />
</parameters>
</xmlcall>
output:
RESPONSE:
<xmlcallresult requestId="REQ-1" name="TestDirectChannels-Google" status="OK">
<page>http://code.google.com</page>
<body><!DOCTYPE html... (omitted)
</xmlcallresult>
INFO: disconnected
