Sample programs

RCI callback

An RCI callback involves two types of actions, demonstrated in the following programs:

 Making RCI requests from Python applications

 Extending RCI to allow iDigi to make requests of Python applications. This is known as

an RCI callback.

Make an RCI request-example program

import rci (1)

request_string=""" (2)

<rci_request version="1.1">

<query_state>

<interface_info name="eth0">

<ip/>

</interface_info>

</query_state>

</rci_request>

"""

print rci.process_request(request_string) (3)

Program notes

1 The rci module includes the process_request function needed by the program.

2 A string representing the RCI request is needed. The sample uses the Python multi-line

string syntax to make it clearer that the XML represents a request for the current IP address

of the Ethernet interface. Combining the lines into a single string on one line would work in

the same way.

3 The RCI XML is submitted for parsing, and the resulting string is returned. In this sample,

the result is simply printed.
