I have a page that sends JSON data with ajax to a perl file, but I'm a bit lost in retrieving the data. Many posts out there are about generating JSON and sending it, but it's not what I need. So here's the jquery section of the sending page: 
$(function(){
 // $Date is perl of course 
var json=jQuery.parseJSON(\'{"DATE":"'.$Date.'"}\');

  json["address"]="123 some street";
  // other functions generate more fields. and call postM()
  postM();

function postM(){
 $.ajax({
    url: "params.pl",
    type: "GET",
    processData: false,
    data: JSON.stringify(json),
    dataType: "text",
    async: true,
    success: function(msg){ alert("perl says: "+msg); }
 }); // ajax
} // postM

}); // jquery

and here's all of the param.pl file 
#!/usr/bin/perl
use strict; use CGI ':standard';
use CGI::Carp "fatalsToBrowser";

my $req=$ENV{QUERY_STRING}; my $i='0';
my $ref=$ENV{HTTP_REFERER};
my $p=param('data');
my $ad=param('address');
my $num_args = $#ARGV + 1;

$i++ if $p;
$i++ if $ad;
$i++ if $req;

my $file='json.txt';
open FH,'>',$file;
print FH "R:$ref
Q:$req
A:$ad
P:$p
G:$ARGV[0]

"; close FH; wait;
my $fsz= -s $file;

print header,"file Sz:$fsz ARGV: $num_args I: $i";

This works ok while jquery sections has type: "GET" but read POST is better way to handle things, though it fails if I change it. Also, when I do get the data, there's a bunch of backslashes and I feel there's got to be a better way. Also note: "processData" is set to false with jquery since I don't know the exact parameter names being transferred. Any help would be appreciated. Thank you perl monk masters.
