Hello,

about module websocket, is it possible to associate a value with the TCP connection and have this value readable when handling SIP requests on that connection?

Hello, I have found a way to do it using htable.

Here is the gist of it in case someone else needs this:

loadmodule "xhttp.so"

loadmodule "websocket.so"

modparam("htable", "htable", "websocket=>size=10")  

route {

    if(proto == WS) {

        xlog("L_DEBUG", "WebSocket check: conid=$conid val=$sht(websocket=>$conid)\n");

    }

}

event_route[xhttp:request] {

    if (ws_handle_handshake()) {

        # successful connection

#adding $conid to hash table

        $sht(websocket=>$conid) = $hu; 

        exit;

     }

}

event_route[websocket:closed] {

    xlog("L_DEBUG", "WebSocket connection from $si:$sp has closed\n");

    # deleting $conid from hash table

    $sht(websocket=>$conid) = $null;

}

Checking again, deletion of the entry in the hash table is failing.

In older versions of kamailio, if I am not mistaken, i used:

  $sht(websocket=>$conid) = null;

but it seems in recent version null was replaced with $null (as if i use null, kamailio will not start)

so I am using

    $sht(websocket=>$conid) = $null;

but it seems this doesn't work.

So, how do we currently delete an htable entry at config file?
