[SR-Users] Re: $hdr behaviour using jansson+http_connect

Hi You have quotes around these variables. $var(ruri) = "$ru"; #request URI $var(from) = "$hdr(From)"; #$fU From header $var(to) = "$hdr(To)"; #$tU; To header $var(contact) = "$hdr(Contact)"; #Contact header $var(callID) = "$ci"; # Call ID $var(identity) = "$hdr(Identity)"; # Identity header That seems like it's not what you want. I'm not sure, but I suspect it might be causing your problems. The last one, for example, does not put the Identity value into the variable, but puts the fourteen-character string "$hdr(Identity)" into the variable. Then I'm not sure what happens after that, but the jansson functions may be resolving the variable somehow and getting it wrong. Note that the $var variables are internal to the SIP workers, not tied to the SIP message or transaction, and that they keep their values from a previous message when processing a new SIP message. My suggestions are these. - Try removing the quotes. - Try adding logging so that you can see what's going on at each step. $var(identity) = $hdr(Identity); xlog("L_WARN", "[$ci] Identity variable has value $var(identity)\n"); James On Fri, 18 Oct 2024 at 13:56, Sergio Charrua via sr-users &lt;sr-users(a)lists.kamailio.org&gt; wrote: been simplified and is something like: Call comes from SBC to Kamailio, Kamailio makes an HTTP request to a REST API, response is received by Kamailio (5.8.2) and depending on the response, it replies back to SBC with a SIP 300 Multiple Choice of a SIP 4xx error, denying the call. the JSON object sent to REST API: "$var(post)"); "$var(post)"); "$var(post)"); "$var(post)"); "$var(post)"); "$var(post)"); "application/json","$var(post)","$var(result)"); 10.240.AAA.BBB:5064;branch=z9hG4bK+30f178b47ee25dd589f986ed7402b4eb3+sip+6+a64eb889 ;user=phone>;tag=10.240.AAA.BBB+6+ffe686f8+614d17a3 <sip:10.240.AAA.BBB:5064>;method="NOTIFY;Event=telephone-event;Duration=2000" 0gQAAC8WAAACBAAALxYAAHRfFdrMLbnN/iMYu2NTT6kvhuhZAFl7MG1V2ozJLUcXg9dxbyQZ/PtoswtdHtcv9g--(a)10.240.AAA.BBB dGhpcyBpcyBzb21lIGR1bW15IGJhc2U2NCBlbmNvZGVkIElkZW50aXR5IGhlYWRlcg==.eW91IHdvdWxkIG5vdCBleHBlY3QgbWUgdG8gbGVhdmUgdGhlIHJlYWwgdmFsdWUgaGVyZSByaWdodD8=.dGhhbmtzIGZvciB5b3VyIGNvbXByZWhlbnNpb24=;info=< https://someURL.com/with/some/parameter;sc697295b.cer kamailio Identity header. so they are different calls and can be perfectly found in logs as separated calls above, and sends the JSON request to HTTP REST API JSON object request sent to the HTTP REST API contains an Identity value, supposedly extracted from the SIP header *but* the SIP message captured in SNGrep doesn't have *any* Identity header!! In fact, in the kamailio logs, where I sent the header values extracted from INVITE, the identity is empty! BUT the JSON object has the identity set with value. Identity set in JSON belongs to a completely different call that was processed a few minutes before ! and added the following lines before sending the JSON to REST API: did not work either! every request was unique, and that did not work either! these lines: "$var(post)"); header using @hf_value2.Identity the sender!
