Hi all,

as a wrap up to this thread, since there were some private exchanges, this summarises what can be correctly used (tested with version 4.4):

$var(target_url) = "http://test.com";

$http_req(method) = "PUT";

http_append_header("Content-Type: application/json");

$var(payload) = '{ "key1" : "value1", "key2" : "' + $fU + '" }';

http_async_query("$var(target_url)", "$var(payload)", "HTTP_REPLY");

which would result in something like:

PUT / HTTP/1.1.

Host: test.com.

Accept: */*.

Content-Type: application/json.

Content-Length: 38.

{ "key1" : "value1", "key2" : "sipp" }

$var(payload) can be constructed by concatenating the needed strings, including pseudovariables, and timestamps can be computed with $TV() and again concatenated in the payload as needed. The payload string has to be escaped as expected by the web service.

Cheers,

Giacomo

Hi Agalya,
can you please provide an example of the data format you'd like to use and the related http_async parameters and request?
And possibly also an example of expected final content of the HTTP request?
We'll try to better understand what you want achieve.

Cheers,
Giacomo

Hi team,

We are trying to use kamailio for our project purpose, which will be used as a proxy server.

Am trying to use “http_async_client” module to send my rest queries asynchronously.

I have few queries regarding the usage of http_async_query() and using PUT method.

http_append_header("Authorization: Bearer $var(auth)");

http_append_header("Content-Type: application/json");

http_set_method("PUT");

http_async_query("http://sdk-evm-wcdc-c-001.rtc.sys.comcast.net/events/createxmpprooteventfortn", "{'from_tn':'$fU','to_tn':'$tU','callid':'ci'}", "HTTP_REPLY");

Here am passing from, to, callid in post data field.

Passing as ‘key’:’value’ is mandatory or I can pass only value- ?

In the file, async_http.c – in async_send_query(), if I modify the post data to the format I need, I see the value is truncated up to three fields only.

How can I achieve that my payload format whatever I form in async_send_query(),doesn’t get truncated and will be passed to the server-?

Can you please explain how this works-?

Also, I observed that kamailio is restricting the content-length of HTTP request to 256.

Is this something modifiable-? If so please guide me how this can be achieved.

Regards,
Agalya
