[SR-Users] issue sending http_async_client POST request

Hi folks, I am using kamailio -v version: kamailio 5.0.2 (x86_64/linux) flags: STATS: Off, USE_TCP, USE_TLS, USE_SCTP, TLS_HOOKS, DISABLE_NAGLE, USE_MCAST, DNS_IP_HACK, SHM_MEM, SHM_MMAP, PKG_MALLOC, Q_MALLOC, F_MALLOC, TLSF_MALLOC, DBG_SR_MEMORY, USE_FUTEX, FAST_LOCK-ADAPTIVE_WAIT, USE_DNS_CACHE, USE_DNS_FAILOVER, USE_NAPTR, USE_DST_BLACKLIST, HAVE_RESOLV_RES ADAPTIVE_WAIT_LOOPS=1024, MAX_RECV_BUFFER_SIZE 262144, MAX_LISTEN 16, MAX_URI_SIZE 1024, BUF_SIZE 65535, DEFAULT PKG_SIZE 8MB poll method support: poll, epoll_lt, epoll_et, sigio_rt, select. id: unknown compiled on 10:02:27 Jul 4 2017 with gcc 4.9.2 I was trying to send http POST request to my web server example.com following example Example 1.12. http_async_query() usage <https://www.kamailio.org/docs/modules/5.0.x/modules/http_async_client.html#http_async_client.f.http_async_query> https://www.kamailio.org/docs/modules/5.0.x/modules/http_async_client.html according to that we should send parameters in body like # POST $http_req(body) = "{'r_uri':'" + $rU + "', 'f_uri':'" + $fU + "'}"; http_async_query("http://example.com/test.php", "HTTP_REPLY"); But its not working out of the box as described with error message from server: INFO: <script>: route[HTTP_REPLY]: status 400 INFO: <script>: route[HTTP_REPLY]: body Insufficient parameters. I even tried adding additional parameters $http_req(hdr) = "Content-Type: application/x-www-form-urlencoded"; $http_req(method) = "POST"; But again it didn't work. I tried the alternative way which worked fine. # POST $http_req(body) = "r_uri=$rU&f_uri=$fU"; http_async_query("http://example.com/test.php", "HTTP_REPLY"); Is there any issue with documentation or i am missing something for POST request? -- regards, abdul basit | p: +92 32 1416 4196 | o: +92 30 0841 1445
