This module is an implementation of an XMLRPC client used to notify XMLRPC servers whenever certain notifications are raised by OpenSIPS. It acts as a transport layer for the Event Notification Interface.
Basicly, the module executes a remote procedure call when an event is raised from OpenSIPS's script, core or modules using the Event Interface.
In order to be notified, an XMLRPC server has to subscribe for a certain event provided by OpenSIPS. This can be done using the generic MI Interface (event_subscribe function) or from OpenSIPS script (subscribe_event core function).
'xmlrpc:' host ':' port ':' method
'xmlrpc:' - informs the Event Interface that the events sent to this subscriber should be handled by the event_xmlrpc module.
host - host name of the XMLRPC server.
port - port of the XMLRPC server.
method - method called remotely by the XMLRPC client.
NOTE: the client does not wait for a response from the XMLRPC server.
This is an example of an event raised by the pike module when it decides an ip should be blocked:
Example 1.1. E_PIKE_BLOCKED event
POST /RPC2 HTTP/1.1. Host: 127.0.0.1:8081. Connection: close. User-Agent: OpenSIPS XMLRPC Notifier. Content-type: text/xml. Content-length: 240. . <?xml version="1.0"?> <methodCall> <methodName>e_dummy_h</methodName> <params> <param> <value><string>E_MY_EVENT</string></value> </param> <param> <name>ip</name> <value><string>192.168.2.11</string></value> </param> </params> </methodCall>
