This module implements a xmlrpc server that handles xmlrpc requests and generates xmlrpc responses. When a xmlrpc message is received a default method is executed.
At first, it looks up the MI command. If found it parses the called procedure's parameters into a MI tree and the command is executed. A MI reply tree is returned that is formatted back in xmlrpc. The response is built in two ways - like a string that contains the MI tree nodes information (name, values and attributes) or like an array whose elements are consisted of each MI tree node stored information.
The following libraries or applications must be installed before running OpenSIPS with this module loaded:
Commands with large responses (like ul_dump) will fail if the configured size of the httpd buffer is to small (or if there isn't enough pkg memory configured).
Future realeases of the httpd and mi_xmlrpc_ng modules will address this issue.
This is an example showing the xmlrpc format for the “get_statistics net: uri:” MI commad: response.
