[Freeswitch-users] Add new line ending after mod_event_socket JSON event

[Mahmood Alkhalil]

Hi,

So I figured it out

static switch_status_t read_packet(listener_t *listener, switch_event_t **event, uint32_t timeout)
{
       switch_size_t mlen, bytes = 0;
       char *mbuf = NULL;
       char newLine[2] = "\n";  //added this new line str
       char buf[1024] = "";
       switch_size_t len;
       switch_status_t status = SWITCH_STATUS_SUCCESS;
.
.
.
.
.

if (switch_test_flag(listener, LFLAG_EVENTS)) {
                               while (switch_queue_trypop(listener->event_queue, &pop) == SWITCH_STATUS_SUCCESS) {
                                       char hbuf[512];
                                       switch_event_t *pevent = (switch_event_t *) pop;
                                       char *etype;

                                       do_sleep = 0;
                                       if (listener->format == EVENT_FORMAT_PLAIN) {
                                               etype = "plain";
                                               switch_event_serialize(pevent, &listener->ebuf, SWITCH_TRUE);
                                       } else if (listener->format == EVENT_FORMAT_JSON) {
                                               etype = "json";
                                               switch_event_serialize_json(pevent, &listener->ebuf);
                                               strcat(listener->ebuf, newLine); //concatenate new line str to the event
                                       } else {
                                               switch_xml_t xml;
                                               etype = "xml";

                                               if ((xml = switch_event_xmlize(pevent, SWITCH_VA_NONE))) {
                                                       listener->ebuf = switch_xml_toxml(xml, SWITCH_FALSE);
                                                       switch_xml_free(xml);
                                               } else {
                                                       switch_log_printf(SWITCH_CHANNEL_SESSION_LOG(listener->sessio>
                                                       goto endloop;
                                               }
                                       }

Subject: [Freeswitch-users] Add new line ending after mod_event_socket JSON event

Hi FS Community,

I'm trying to add a '\n' new line after the JSON event sent from FS on the mod_event_socket when the event type is JSON, I need to do so as I'm writing a JAVA event parser and it would make the code much simpler if I can add this new line after the event.

I'm not able to know where to edit exactly in the mod_event_scoket file (I have no experience in C lang at all) but I think it is somewhere around line 1274.

If someone could help with this, I would really appreciate it.

(the java socket lib am writing uses Netty DelimiterBasedFrameDecoder on '\n' nut it breaks as after the JSON event there is no new line and Content-Length: is directly written after the JSON event)
