Looks like JSON::XS does the job:


use JSON::XS;
use Data::Dumper;

my %hash = ( cl_ip => 209890 );

my $json = encode_json \%hash;

print Dumper( \%hash );

print qq($json\n);

__END__

$VAR1 = {
          'cl_ip' => 209890
        };
{"cl_ip":209890}

Update:

I worry a bit about this. The OP wrote:

"...some strings that were supposed to be converted to integers are still strings...So a data dump looks good: 'cl_ip' => 209889, But there's a string in the json file for this key: "cl_ip":"209889"..."

From the JSON::XS manual:

"...Its primary goal is to be correct..."

The OP expects that the value of cl_ip is an integer after encoding, right?

In my example using JSON::XS the OP gets what he wants (integer).

IMHO JSON::XS works as designed - the result is what the OP expected.

If i still miss something: thanks for any advice.

I hope i didn't miss something. Regards Karl
