Hello, I can contribute a python part, but currently I'm a very busy at the moment. I will write a patch to enable this ability (and many other features) as soon as possible.

Hello,

the best would be to enhance the module to be able to get/set pseudo-variables. I am not a python guy at all, so I cannot help much, however I can assist with the C side in kamailio if someone starts development and has questions about PVs.

Calling config functions with parameters from embedded interpreters exposes the risk of memory leaks, so it is better to avoid it. Anyhow, added headers are not visible immediately (even when done form config file), unless you call msg_apply_changes().

As a workaround for now, I suggest you put your token somehow in request uri (e.g., a parameter).

Cheers, Daniel

Hi,

is there any way to return values from a call to python_exec function orther than the default returned integer?

Following code generates this error: Oct 1 09:08:23 zskio /usr/sbin/kamailio[21789]: ERROR: app_python [python_support.c:38]: python_exec2: Unhandled exception in the Python code: Oct 1 09:08:23 zskio /usr/sbin/kamailio[21789]: ERROR: app_python [python_support.c:78]: #011RuntimeError: no such function

             if (!python_exec("get_provider",

$(var(clean_uri){s.prefixes}))**) { xlog("L_ERR","Can not choose a provider for $rU\n"); sl_send_reply("503","Can not choose a provider for $rU"); exit; }

def get_provider(self, msg, param): # snipped code... result = self.util.get_provider(**prefixes, position, mode) if result is not None: LM_ERR("mode: %s position: %d result: %s" % (mode, position, result)) # this raises error msg.call_function('**rewritehost', result['provider']['ip']) return 1 return -1

I tried to use headers as transport but this simple code does not work:

Oct 1 09:45:31 zskio /usr/sbin/kamailio[22303]: ERROR: <script>: No header

             if (!is_present_hf("X-Test-**header")) {
                     xlog("L_ERROR", "No header\n");
             }
             else {
                     xlog("L_INFO", "Header added\n");
             }

 def test_set_header(self, msg):
     msg.call_function('append_hf', 'X-Test-header: test\r\n')
     return 1

Thanks in advance.

I'm guessing that accessing pseudo-variables is still not possible in python? I haven't seen anything indicating so in any event. Could you confirm? Will probably switch to lua as well.

Hello,

Hi Daniel,

...

the best would be to enhance the module to be able to get/set pseudo-variables. I am not a python guy at all, so I cannot help much, however I can assist with the C side in kamailio if someone starts development and has questions about PVs.

I had to change to lua scripting in order to use pvs.

good choice :-)

It would be good anyhow to update the app_python to work with pvs, but it's not me that can do it, fortunately someone else volunteered.

Cheers, Daniel

Oh. Thanks.

Thanks a lot for your reply.
