[OpenSIPS-Users] How to send multiple parameters to event handlers?

[Mundkowsky, Robert]

Maybe it is possible to pack parameters together using the JSON library?

I just looked at the actual data being sent via tcpdump and openSIPS is not sending multiple values, just the last values set.

Is there some easy way to send multiple values over XMLRPC?

I am using openSIPS 2.2.3 to send events to an external handler via XMLRPC.

The external handler is a XMLRPC daemon written in Python.

The events are sent correctly, but you can only send two parameters based on the "raise_event" function (https://www.opensips.org/Documentation/Script-CoreFunctions-2-2#toc28) .

I tried using AVP variables to pass multiple parameters, but the python handler only sees the last variable set.

For example, in the opensips.cfg file I have:

startup_route {
        subscribe_event("E_SOME_EVENT", "xmlrpc:127.0.0.1:8000:e_dummy_h");
}
...
$avp(attr-val) = NULL;
$avp(attr-val) = "BBB";
$avp(attr-val) = "DDD";
$avp(attr-name) = NULL;
$avp(attr-name) = "AAA";
$avp(attr-name) = "CCC";
raise_event("E_SOME_EVENT", $avp(attr-name), $avp(attr-val));

But the python script only receives the last set values ("DDD" and "CCC").
