[OpenSIPS-Users] May I ask for some help with MI interface please

[Adrian Fretwell]

Hello,

I'm having trouble with any MI command that has parameters over UDP 
MI_DATAGRAM.

Below are a couple of captured packets:

U 2020/07/05 20:24:55.472104 185.222.222.247:34176 -> 
185.222.222.247:9061 #3
{"jsonrpc":"2.0","method":"get_statistics","id":"1075","params":["dialog:","tm:"]}


U 2020/07/05 20:24:55.472233 185.222.222.247:9061 -> 
185.222.222.247:34176 #4
{"jsonrpc":"2.0","error":{"code":-32602,"message":"Invalid 
params"},"id":"1075"}

The request is identical to the example given in 
https://opensips.org/docs/modules/3.0.x/mi_datagram.html But as you can 
see I get an invalid params error  (dialog and tm modules are both loaded).

A command without params is fine, see below:


U 2020/07/05 20:24:23.650924 185.222.222.247:48846 -> 
185.222.222.247:9061 #1
{"jsonrpc":"2.0","method":"which","id":"1065"}

U 2020/07/05 20:24:23.651093 185.222.222.247:9061 -> 
185.222.222.247:48846 #2
{"jsonrpc":"2.0","result":["get_statistics","list_statistics","reset_statistics","uptime","version","pwd","arg","which","ps","kill","log_level","xlog_level","shm_check","cache_store","cache_fetch","cache_remove","event_subscribe","events_list","subscribers_list","list_tcp_conns","mem_pkg_dump","mem_shm_dump","mem_rpm_dump","reload_routes","help","list_blacklists","t_uac_dlg","t_uac_cancel","t_hash","t_reply","dlg_list","dlg_list_ctx","dlg_end_dlg","dlg_db_sync","dlg_restore_db","dlg_cluster_sync","profile_get_size","profile_list_dlgs","profile_get_values","list_all_profiles","profile_end_dlgs","dlg_push_var","dlg_send_sequential","ul_rm","ul_rm_contact","ul_dump","ul_flush","ul_add","ul_show_contact","ul_sync","ul_cluster_sync","nh_enable_ping","refreshWatchers","refresh_watchers","cleanup","pres_expose","pres_phtable_list","subs_phtable_list","pua_publish","pua_subscribe","rls_update_subscriptions","tcp_trace"],"id":"1065"}

Most of the documentation for the modules still shows the old non JSON 
way of communicating.  Can someone point me in the right direction please.


Kind regards,
