[sr-dev] Parsing list of headers

[Ionut Razvan Ionita]

Hi all,


In the end I was successfull using param.value transformations for the parameters in the header and tobody.uri to get the URI. Thank you for your your help!

Hello all,


I am trying to implement RFC 7544 in kamailio.cfg, more specifically to transform Diversion header into History-Info. To do this I need to iterate over all Diversion headers and be able to get all the parameters from it. At first I discovered $di core variable, but I can access only the first header with it. I discovered kamailio selectors but I can't index them with a variable. I came to the point where I want to implement variable indexing to selectors but after I saw this API is quite complex I thought to ask here if there's any other solution to do this?!

if you refer to $sel(...) and they do not support variables for index, you can try:

  - double evaluation using pv_evalx() - https://www.kamailio.org/docs/modules/devel/modules/pv.html#pv.f.pv_evalx

  - use an embedded script with inline execution -- eg app_jsdt doesn't have external dependencies and you can run a small javascript script where you can use local variables for index and construct the $sel() as you need, then pass that to KSR.pv.get(...).


Cheers,
Daniel
