Hi folks, I am using 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
