Hi Giacomo,
I have few questions with regard to rest client in kamailio.
1) I see there are two modules in kamailio for rest client. http_client,
http_async_client.
I hope http_client does the http transfer in synchronous way.
http_async_client does the http transfer in asynchronous manner.
Correct me if am wrong here.
2) I want to achieve https transfers in async way, so choosing http_async_client.
Is there a way that kamailio maintains persistent TCP connection pooling for http
transfer.
I see there is a "workers" parameter in http_async_client. By increasing this
number does it result it more http request's handling?
3) Also, I have some questions regarding documentation for module http_async_client
in 5.0 version.
In the API exposure, it says "http_async_query(url, route_name)".
But the example if I want to use POST, it says
"http_async_query("http://example.com/test.php",
"{'r_uri':'$rU', 'f_uri':'$fU'}",
"HTTP_REPLY");"
There is a parameter mismatch between the example and the actual function.
If I try to use GET query, kamailio service is starting. But if I try to give the POST
query with payload, kamailio service is not started.
It says, sctp_core_destroy(): SCTP API not initialized.
Also I have noticed that, functions like http_append_header(),http_set_method() are
removed in 5.0 version, whereas we have this API's is 4.x versions.
Is there some issue with the documentation for 5.0 ?
Please let me the know the details for the above queries.
Regards,
Agalya

I used it like this and it works -
http_async_query("http://TEXT_BROKER/api/events/CallAnswered",
"{'CallId':'$ci', 'Time' : '$TF'}",
"HTTP_REPLY");
Issue may be with quotes. Make sure you don't have " in the second parameter
content. If you send Kamailio log it will be easier to debug.
Please let me the know the details for the above queries.

Hi,
reusing the same connection to the same url is delegated to liburl, so you
can have that when using http_async_client.
More workers will increase the capacity at the price of resources (shared
memory).
I wrote a wrap up about building the request payload here:
https://lists.kamailio.org/pipermail/sr-users/2016-December/095454.html -
please double check escaping.
The function methods have been reviewed in version 5 and removed, replaced
by pseudovariable settings which is more common practice in kamailio.
Instead of http_append_header() use
$http_req(hdr) = "X-theheader: the value";
Instead of http_set_method() use
$http_req(method) = "POST";
The latest documentation requires a little review for some mentions of the
old functions. Will try to fix as soon as possible.
Best Regards,
Giacomo

I have updated the http_async_client documentation for master and 5.0.
Please note that in respect to 4.4 http_async_query() now only takes 2
parameters: the payload is passed with $http_req(body).
