Hello,

the rpc interface is not matching parameters by name, but by possition. You can add them with name, but must be at the right/expected possition.

In your last example, body field is out of parameters structure. And as it was pointed out before, you need an id in the root jsonrpc structure.

See some examples at:

  - https://www.kamailio.org/docs/modules/stable/modules/jsonrpcs.html#idm1028042236

Cheers,
Daniel

Hello Serge,

Thank you for clarifying this for me. But there is different issue when I change format. It appears that Kamailio indeed expects body under parameters https://www.kamailio.org/docs/modules/5.2.x/modules/pua_rpc.html#pua_rpc.r.pua.publish.

I run:

# curl -H "Content-Type: application/json" -X POST -d '{"jsonrpc": "2.0", "method": "pua.publish", "params": {"presentity_uri": "sip:jh@test.tutpro.com", "expires": "600", "event package": "message-summary", "content type": "application/simple-message-summary", "id": "4ce8c647a7b947c@172.16.30.151", "ETag": ".", "outbound proxy": "sip:127.0.0.1:5060;transport=udp", "extra_headers": "P-Flags: 0"}, "body": 1}' http://172.16.30.151:5060/JSON_RPC

Result:

{

        "jsonrpc":      "2.0",

        "error":        {

                "code": 400,

                "message":      "Body is missing"

        }

}

Hi

id is not inside params but must to be at top-level.

You have to read JSONRPC specs %)
