mi_xmlrpc_ng Module

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.

1.2. Dependencies

1.2.1. External Libraries or Applications

The following libraries or applications must be installed before running OpenSIPS with this module loaded:

libxml2

1.2.2. OpenSIPS Modules

The following modules must be loaded before this module:

httpd module.

1.3. Exported Parameters

1.3.1. `mi_xmlrpc_ng_root`(string)

Specifies the root path for xmlrpc requests: http://[opensips_IP]:[opensips_httpd_port]/[mi_xmlrpc_ng_root]

The default value is "RPC2".

Example 1.1. Set mi_xmlrpc_ng_root parameter

...
modparam("mi_xmlrpc_ng", "mi_xmlrpc_ng_root", "opensips_mi_xmlrpc")
...

1.4. Exported Functions

No function exported to be used from configuration file.

1.5. Known issues

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.

1.6. Example

This is an example showing the xmlrpc format for the “get_statistics net: uri:” MI commad: response.

Example 1.2. XMLRPC request
