Hello,

Are you getting any error message in the log files? Are you able to execute the query e.g. by command line?

Cheers,

Subject: [SR-Users] MongoDB query from Kamailio help needed

Help is needed. I know I have seen a similar problem either via email or google search but for the life of me I cannot find it now. 

I am using:

Ubuntu:

5.4.0-144-generic #161-Ubuntu SMP Fri Feb 3 14:49:04 UTC 2023 x86_64 x86_64 x86_64 GNU/Linux

Kamailio:

version: kamailio 5.3.9 (x86_64/linux)  -- This is a dev platform and I can update kamailio if needed.

I am trying to query a mongodb collection for the phone number stored under “did” as an integer and make a decision based on the returned result (boolean is sufficient for this decision). 

I don’t know what I am doing wrong here. Any help will be well appreciated

##### This is the insert statement into the telephone db from a linux script

db.c$coll.insertOne({"did":parseInt($(cut -d_ -f 1 <<< $1)), "callDesc":$(cut -d_ -f 1 <<< $1)}))" >> $(cut -d_ -f 1 <<< $1).js

did is stored as an integer and the callDesc is stored as presented by $rU

{ "_id" : ObjectId("641580b4863678d0ba38d69a"), "did" : 1XXXXXXXXXX, "callDesc" : 1XXXXXXXXXXXX }

> db.c234.find()

{ "_id" : ObjectId("641580b4863678d0ba38d69a"), "did" : 2XXXXXXXXXXXX, "callDesc" : 2XXXXXXXXXXXX }

> db.c234.find()

{ "_id" : ObjectId("641580b4863678d0ba38d69a"), "did" : 3XXXXXXXXXXXX, "callDesc" : 3XXXXXXXXXXXX }

Kamailio config:

# --- mongodb module loaded 202201082322

loadmodule "ndb_mongodb.so"

if (uri==myself)

{

sl_send_reply("100", "Trying to check if uri is myself $rU $ru");

#return;

#Adding this to test connection to mongodb…. This worked and the reply was sent to the endpoint

if(mongodb_cmd_simple("mongodbsrv1", "telephone", "cXXX”, "{ \"collStats\": \"cXXX\” }", "mgr1"))

{

sl_send_reply("183", "I got inside this message loop $rU found in mongodb");

xlog("response from mongodb is [[$mongodb(mgr1=>value)]]\n");

}

# End of the test

#This is to run the actual db query to test if the phone number is in the mongodb…. I am not successful at this query even when the number is known to be in the database

if(mongodb_find_one("mongodbsrv1", "telephone", "cXXX”, "{\"did\" : \"$rU\" }", "mongoResponse1"))

{

# Route to confirmed route here -- 202302212032

sl_send_reply("183", "I got inside this mongodb message loop");

route(CONFIRMED_ROUTE);

xlog("response from mongodb is [[$mongodb(mongoResponse1=>value)]]\n");

}

else

{

route(UNCONFIRMED_ROUTE);

}

}

#append_hf("P-hint: outbound\r\n");

route(RELAY);

#exit;

}

Please help.
