[SR-Users] kamailio & redis

[Fabian Pignataro]

Hello Community,

I'm trying to read data (hash) stored in redis database, from kamailio
script.

I read the module documentation ndb_redis:
http://www.kamailio.org/docs/modules/4.4.x/modules/ndb_redis.html#idp26300788
But I'but I don't understand what I'm doing wrong :/

With someone has had experience this?

*My platform:*

*root at kamailio-fts:~# cat /etc/issue*
*Ubuntu 14.04.4 LTS \n \l*

*root at kamailio-fts:~# kamailio  -V*
*version: kamailio 4.4.1 (x86_64/linux) *
*flags: STATS: Off, USE_TCP, USE_TLS, USE_SCTP, TLS_HOOKS, USE_RAW_SOCKS,

USE_DST_BLACKLIST, HAVE_RESOLV_RES*
*ADAPTIVE_WAIT_LOOPS=1024, MAX_RECV_BUFFER_SIZE 262144, MAX_LISTEN 16,

*poll method support: poll, epoll_lt, epoll_et, sigio_rt, select.*
*id: unknown *
*compiled with gcc 4.8.2*

*My script:*

*modparam("ndb_redis", "server", "name=srvN;addr=127.0.0.1;port=6379;db=1")*
*modparam("ndb_redis", "init_without_redis", 1)*

*if(redis_cmd("srvN", "HMGET usuario:2002 status", "res")) {*
*xlog("L_INFO","array size: $redis(res=>size) - type: $redis(res=>type) -
value: $redis(res=>value[0]) $redis(res=>value[1]) \n");     *
* }*

*The output of syslog (I don't see errors): *

It can be seen that $redis(res=>size) & $redis(res=>type) return values,
not so with $redis(res=>value[0]).

*By last, I share de output of redis CLI:*

*127.0.0.1:6379 <http://127.0.0.1:6379>> hget usuario:2002 status *
*"Online" *

Cheers,
