[sr-dev] Re: [kamailio/kamailio] CDP / IMS Diameter Server Module- diameter_request() function fails to send/forward request (#2035)

I've tried to send Sh requests to HSS via xhttp -> diameter_request and found that after successful call I've always got empty $diameter_response. After reading code of ims_diameter_server module I made following patch to finally get responses: ``` --- a/src/modules/ims_diameter_server/avp_helper.c +++ b/src/modules/ims_diameter_server/avp_helper.c int pv_get_response(struct sip_msg *msg, pv_param_t *param, pv_value_t *res) { - if ((msg->id != current_msg_id_repl) || (responsejson.len < 0)) { + if (responsejson.len < 0) { return pv_get_strval(msg, param, res, &responsejson); ``` but then I thought that there should be workaround for unpatched version, so here's little hack to set empty $diameter_response before calling diameter_request function: ``` # # Processing HTTP request, it should be POST, # with URI: http://host:port/lcs/diameter-peer-name/diameter-app-id/function-code # event_route[xhttp:request] { xlog("Recieved HTTP request with request $hu\n"); # make diameter_request function happy -- initialize $diameter_response ;) # without setting $diameter_response first - there's no way to get back response_data $diameter_response = ''; xlog('trying to call: "diameter_request($(hu{s.select,2,/})", $(hu{s.select,3,/}), $(hu{s.select,4,/}), rb);\n'); diameter_request($(hu{s.select,2,/}), $(hu{s.select,3,/}), $(hu{s.select,4,/}), $rb); xlog("Received Diameter response:\n"); # xlog("$diameter_response \n"); xhttp_reply("200", "OK", "application/json", "$diameter_response"); } ``` -- Reply to this email directly or view it on GitHub: https://github.com/kamailio/kamailio/issues/2035#issuecomment-1673511815 You are receiving this because you are subscribed to this thread.
