I want to send  a associative array as a value in json array.



for example i create a array like.


%responce_array1=();

$responce_array1{'REQUEST'}{'Items'{0}{'ItemName'}='demoName0';
$responce_array1{'REQUEST'}{'Items'}{1}{'ItemName'}='demoName1';
$responce_array1{'REQUEST'}{'Items'}{2}{'ItemName'}='demoName2';


my $itemjson_ary1 = encode_json \%responce_array1;


and pass it to as a value of a another array like :-

%responce_array2=();

$responce_array2{'item_json_array'}=$itemjson_ary1;

and json encode it like :-

my $itemjson_ary2 = encode_json \%responce_array2;

it gives out put  as below json encoded array.:-


print $itemjson_ary2;

$jsonary='{"item_json_array":"{\"REQUEST\":{\"Items\":{\"1\":{\"ItemName\":\"demoName1\"},\"0\":{\"ItemName\":\"demoName0\"},\"2\":{\"ItemName\":\"demoName2\"}}}}"}';


Now the problem is  how can  i retrive "ItemName" value.

because for  example i  take  three values  like 0,1,2 but these can be  many 0,1,2,3,4...

so i want to retrieve all these value in a loop.or any  way to convert it in to array so we can get these array.

my whole code as follows.


use JSON;

%responce_array1=();
%responce_array2=();


$responce_array1{'REQUEST'}{'Items'{0}{'ItemName'}='demoName0';
$responce_array1{'REQUEST'}{'Items'}{1}{'ItemName'}='demoName1';
$responce_array1{'REQUEST'}{'Items'}{2}{'ItemName'}='demoName2';

my $itemjson_ary1 = encode_json \%responce_array1;

$responce_array2{'item_json_array'}=$itemjson_ary1;

my $itemjson_ary2 = encode_json \%responce_array2;

print $itemjson_ary2;

$jsonary='{"item_json_array":"{\"REQUEST\":{\"Items\":{\"1\":{\"ItemName\":\"demoName1\"},\"0\":{\"ItemName\":\"demoName0\"},\"2\":{\"ItemName\":\"demoName2\"}}}}"}';


#here  i am decode these json array to get "item_json_array" value .

$dec_json_obj = decode_json $jsonary;
$temp=$dec_json_obj->{item_json_array};



#here  i am decode these json array to get "REQUEST" value .

$dec_json_obj = decode_json $temp;
$temp=$dec_json_obj->{REQUEST}; #hash form
$dec_json_obj=&get_hash_to_str($temp);



#here  i am decode these json array to get "Items" value .
$temp=$dec_json_obj->{Items};
$dec_json_obj=&get_hash_to_str($temp);


#here  i am decode these json array to get "0" value .
$temp=$dec_json_obj->{0};
$dec_json_obj=&get_hash_to_str($temp);


#here  i am decode these json array to get "ItemName" value .
print $temp=$dec_json_obj->{ItemName};

#out put is demoName0

# its subroutine to convert hash to string

sub get_hash_to_str($temp)
{
my $temp=$_[0];
my $enc_json_req = encode_json $temp;
print"
";
print $enc_json_req;
print"
";
my $dec_json_obj = decode_json $enc_json_req;
return $dec_json_obj;
}
