Chapter 52. IRC

IRC Component

The irc component implements an IRC (Internet Relay Chat) transport.

URI format

irc:nick@host[:port]/#room[?options]
In Apache Camel 2.0, you can also use the following format: 
irc:nick@host[:port]?channels=#channel1,#channel2,#channel3[?options]
You can append query options to the URI in the following format, ?option=value&option=value&...

Options

Name Description Example Default Value
channels New in 2.0, comma separated list of IRC channels to join. channels=#channel1,#channel2 null
nickname The nickname used in chat. irc:MyNick@irc.server.org#channel or irc:irc.server.org#channel?nickname=MyUser null
username The IRC server user name. irc:MyUser@irc.server.org#channel or irc:irc.server.org#channel?username=MyUser Same as nickname.
password The IRC server password. password=somepass None
realname The IRC user's actual name. realname=MyName None
colors Whether or not the server supports color codes. true, false true
onReply Whether or not to handle general responses to commands or informational messages. true, false false
onNick Handle nickname change events. true, false true
onQuit Handle user quit events. true, false true
onJoin Handle user join events. true, false true
onKick Handle kick events. true, false true
onMode Handle mode change events. true, false true
onPart Handle user part events. true, false true
onTopic Handle topic change events. true, false true
onPrivmsg Handle message events. true, false true
trustManager New in 2.0, the trust manager used to verify the SSL server's certificate. trustManager=#referenceToTrustManagerBean The default trust manager, which accepts all certificates, will be used.
keys Camel 2.2: Comma separated list of IRC channel keys. Important to be listed in same order as channels. When joining multiple channels with only some needing keys just insert an empty value for that channel. irc:MyNick@irc.server.org/#channel?keys=chankey null
sslContextParameters *Camel 2.9:* Reference to a org.apache.camel.util.jsse.SSLContextParameters in the Registry. This reference overrides any configured SSLContextParameters at the component level. See Using the JSSE Configuration Utility. Note that this setting overrides the trustManager option. \#mySslContextParameters null

Using the JSSE Configuration Utility

As of Camel 2.9, the IRC component supports SSL/TLS configuration through the Camel JSSE Configuration Utility. This utility greatly decreases the amount of component specific code you need to write and is configurable at the endpoint and component levels. The following examples demonstrate how to use the utility with the IRC component.

Programmatic configuration of the endpoint

KeyStoreParameters ksp = new KeyStoreParameters();
ksp.setResource("/users/home/server/truststore.jks");
ksp.setPassword("keystorePassword");

TrustManagersParameters tmp = new TrustManagersParameters();
tmp.setKeyStore(ksp);

SSLContextParameters scp = new SSLContextParameters();
scp.setTrustManagers(tmp);

Registry registry = ...
registry.bind("sslContextParameters", scp);

...

from(...)
    .to("ircs://camel-prd-user@server:6669/#camel-test?nickname=camel-prd&password=password&sslContextParameters=#sslContextParameters");

Spring DSL based configuration of endpoint

...
  <camel:sslContextParameters
      id="sslContextParameters">
    <camel:trustManagers>
      <camel:keyStore
          resource="/users/home/server/truststore.jks"
          password="keystorePassword"/>
    </camel:keyManagers>
  </camel:sslContextParameters>...
...
  <to uri="ircs://camel-prd-user@server:6669/#camel-test?nickname=camel-prd&password=password&sslContextParameters=#sslContextParameters"/>...

Using the legacy basic configuration options

You can also connect to an SSL enabled IRC server, as follows: 
ircs:host[:port]/#room?username=user&password=pass
By default, the IRC transport uses SSLDefaultTrustManager. If you need to provide your own custom trust manager, use the trustManager parameter as follows: 
ircs:host[:port]/#room?username=user&password=pass&trustManager=#referenceToMyTrustManagerBean

Using keys

Available as of Camel 2.2 Some irc rooms requires you to provide a key to be able to join that channel. The key is just a secret word.
For example we join 3 channels where as only channel 1 and 3 uses a key. 
irc:nick@irc.server.org?channels=#chan1,#chan2,#chan3&keys=chan1Key,,chan3key
