Hi,
Any quick thoughts. I am using a REDIS "GET" to retrieve a JSON obj as a
string from REDIS and then the JANSSON get value to extract a key value
from the string and pop it into an AVP ($avp(val)) and wish to ensure the
value is an integer in the AVP. New to this, be kind :-)

You want to validate that the value is an integer, or coerce the internal type of the AVP
to integer?

Hello,
to convert a string value stored in a variable to integer, use the
{s.int} transformation, like:
$avp(intval) = $(var(strval){s.int});
See more about transformations at:

Hi,
I would like to set is an an integer. Forgive me as I am on mobile so this
is from memory. I am getting a string using REDIS something like:
Redis_cmd("dB","GET key:xyz","r")
I now have some string in $redus(r=>value) say
{"this":"that","mum":"3","other":"here"}
I have used the jansson_get to move the value of the specific key into an
AVP for use. If I move the value 3 that is keyed by "num" from the Jason
into the AVP it is a string. I can use $avp(val) = $(avp(val){s.int}) and
that will work but was wondering if there was a more elegant solution to
this?
Just finding my way around this new landscape :-)

Daniel,
Sorry, I did not see your reply as well. I struggle with mobile email! :-)
Yes, as above I used the s.int but was possibly looking at a more elegantly
constructed methid when moving the value into the avp at the start.

I haven't tried and I am not the developer of jansson module, but of you
control how the json doc is written in redis, then you can try to store
the value as number (not enclosed in quotes) and maybe jansson store its
value directly as int in the kamailio.cfg variable.
Otherwise, using {s.int} is the recommended way. I would just store
first in a $var(x) as string value and then move it to $avp(...)
converted to int.
If you store first to $avp(val) and then do:
$avp(val) = $(avp(val){s.int});
you end up with two $avp(val) -- AVPs work as a multi-value stack, an
assignment adds to the top of the stack. Overall, it should be fine,
this is more like a cosmetic change.
Cheers,
Daniel

Daniel,
Thanks, you're a star! I dug into the old stuff that was inserting the
values in REDIS, and *yes* there it was. The database was set as INT,
however the php (7) json_encode was encoding all values as a string.
There is a flag for that function called "JSON_NUMERIC_CHECK" that now
forces the INT values where needed and the object now is passed as an
INT, and then by the jansson_get() function to the avp.
Should have thought about that one. Thanks again :-)
