in reply to Brannigan: hash validation

How about something like:

c:\@Work\Perl\monks\henzen>perl -wMstrict -MData::Dump -le "use JSON; ;; my $json = q{ { \"method\": \"xxx\", \"backend\": { \"client\": \"mytest009\", \"pw\": \"sdkjfhsfjhKJH87\" }, \"blah\": \"123\" }}; my $data = decode_json($json); dd $data; ;; my %valid = map { $_ => 1 } qw(method backend); my @invalid = grep { ! exists $valid{$_} } keys %$data; die qq{invalid keys(s) present: @invalid} if @invalid; " { backend => { client => "mytest009", pw => "sdkjfhsfjhKJH87" }, blah => 123, method => "xxx", } invalid keys(s) present: blah at -e line 1.
Of course, you have to know all the valid keys in advance, and it's only a top-level check, but maybe a starting point.

Give a man a fish:  <%-{-{-{-<
