That's correct, it accepts only one parameter for now.
After many years our company has switched to kamailio, I'm actively working
on new version of app_python, more flexible and usable than current one,
many new features...
I'm not ready to push new changes to current module due to raw alpha and
unstable work.
Right now. as workaround you can pass something like $_s($fu!!$tu) and then
in python parse them with from_user, to_user = $param1.split("!!")

Hello,
not very familiar with the app_python initial design, but when I added
kemi support in it for kamailio 5.0, I think I noticed the limitation of
1 extra parameter. Probably you can encode your parameters in comma
separated value, so you can parse it easier in the python script, as
opposite to parsing the entire message buffer.
An alternative may be getting the value for $fu or $tu if python offers
the api for getting/setting pseudo-variables -- these are for sure in
kemi exports to python.
Of course, if anyone adds support for more parameters, then it will be
accepted inside kamailio repo.
Cheers,
Daniel

Hello,
in our Kamailio, we are using python_exec to execute script used to send
push notifications to Google or Apple.
Currenty, the method we call only accepts the message as parameter. We
then
extract from the message the Call Id, to URI and
from URI.
Here is the python method signature:
*def SendPushNotification(self, msg)*
To extract the toUri and fromUri (and remove the sip:), we use python
regex
:
*uriPattern=re.compile(".*sips?:(.+@[^>;]+)")*
This is working well 99% of the time, except sometimes (we don't know
why)
where we get the error:
*logger_LM_ERR(): Exception occurred: Traceback (most recent call last):
File "mypythonExample.py", line XXX, in SendPushNotification
requestUri = self.ExtractURIFromHeader(msg.getHeader("to"))
File "mypythonExample.py", line XXX, in ExtractURIFromHeader
m= self.uriPattern.match(header);
TypeError: an integer is required*
We tried to analyze the cause of this error, but we didn't find any
problem
with the message itself (the message is complete,
with the *to *and *from
*correctly filled).
So, to avoid using the python regex, we have decided to pass parameters
to
the python script (callId, from and to URI):
*def SendPushRequest(self, msg, fromUri, toUri, callid)*
But it seems python_exec doesn't support more than 2 parameters ($mb and
another one). Is this exact? If this is the case, how can we pass several
parameters from kamailio.cfg?
Thx for your help.
Regards
Giovanni
