I have some code using libonion. Using simple GET requests and queries, it works fine. However, I have one page that is POSTing a simple form. When it posts, the browser spins for about 30-45 seconds before getting a Connection Reset. In my logs, I never see an INFO response message for the requested page. If I initiate a GET request on the same URL/page, it responds just fine (except that I can't get any POST data). I have the syslog() line in the handler, but I never see the log hit my syslog. I suspect I'm not setting up the handler properly.
My code looks like this:
/**
* @short adds a new user to the system
*/
onion_connection_status userAdd_handler(void *none, onion_request *req, onion_response *res) {
char temp[1024];
syslog(LOG_ERR, "userAdd_handler\n");
if (onion_request_get_flags(req)&OR_HEAD){
onion_response_write_headers(res);
return OCS_PROCESSED;
}
onion_dict *post = onion_request_get_post_dict(req);
// alternatively onion_dict *post = onion_dict_from_json(json_data);
onion_block *json = onion_dict_to_json(post);
printf("POST DATA: %s\n", onion_block_data(json));
onion_block_free(json);
onion_dict *out = onion_dict_new();
getUsersTable(out);
onion_response_set_code(res, HTTP_CREATED);
return onion_shortcut_redirect("/user", req, res);
}
static void *webInterfaceThread(void *data) {
onion *server=onion_new(O_ONE_LOOP);
onion_url *url = onion_root_url(server);
onion_set_hostname(server, "0.0.0.0");
onion_set_port(server, "8120");
ONION_INFO("Listening at http://0.0.0.0:8120");
onion_url_add(url, "camImage.png", (void*)camImage_handler);
onion_url_add(url, "accessLog.json", (void*)accessLog_handler);
onion_url_add(url, "accessTable.json", (void*)accessTable_handler);
onion_url_add(url, "userTable.json", (void*)userTable_handler);
onion_url_add(url, "testEmail.smtp", (void*)sendEmail_handler);
onion_url_add_static(url, "user",
"<html><body><form method=POST action=\"/addUser\">"
"<textarea></textarea><input type=\"submit\">"
"</form></body></html>", HTTP_OK);
onion_url_add(url, "addUser", (void*)userAdd_handler);
onion_listen(server);
onion_free(server);
return 0;
}
Any suggestions?

After troubleshooting with tcpdump, it turns out my <textarea> tag had problems. Changing it to an <input> tag worked. I suspect there maybe an issue with a zero-length POSTs.
