Hello all,
I have redis database where the data is inserted in JSON format:
#Redis Command
JSON.GET Index1J:12345678
#Redis Result
[
{
"SupplierID": "7",
"BCode": "987654",
"Rate": 0.159
},
{
"SupplierID": "7",
"BCode": "765432",
"Rate": 0.159
},
{
"SupplierID": "7",
"BCode": "5432159",
"Rate": 0.159
}
]
When I try to get the result using Lua script in Kamailio like the following:
#kamailio command
if KSR.ndb_redis.redis_cmd("srvN", "JSON.GET pricelistJ:441246890",
"ra") then
KSR.xlog.xinfo("array size: $redis(ra=>size)\n");
KSR.xlog.xinfo("Redis Response: " .. tostring(ra) ..
"\n")
KSR.xlog.xinfo("first values: $redis(ra=>value[0]) ,
$redis(ra=>value[1])\n");
end
Nov 7 07:58:15 868d08ee318d /usr/sbin/kamailio[72]: INFO: LUA {INVITE}: <script>:
array size: <null>
Nov 7 07:58:15 868d08ee318d /usr/sbin/kamailio[72]: INFO: LUA {INVITE}: <script>:

Nov 7 07:58:15 868d08ee318d /usr/sbin/kamailio[72]: INFO: LUA {INVITE}: <script>:
first values: <null> , <null>
I'm getting null results.
I don't know what I'm doing wrong here. Can you please assist?

Did you try to use not JSON but usual GET/SET? Do you have the same issue?
AFAIK - ndb_redis is a wrapper oven hiredis wrapper and doesn't implement
serialisation protocol for redis, so, whatever you send delivered to redis
being only wrapped via hirer's client library.
Btw if uou use lua < 5.2 you may try redis-lua library. It is easier to use
with lua.

Hi Yurig,
Yes, GET/SET is working normally from kamailio if not using JSON.
Honestly, I didn’t get what do you mean by the below. Can you please elaborate how to fix
the issue?
