I'm looking to turn a Perl data structure into a CGI query string.

There are several modules that turn query strings into data structures (eg CGI::Struct and CGI::State), but I need to do the opposite.

I've got something like this:

%hash = (
          'name'     => 'test name',
          'file_ids' => [
                          1,
                          2
                        ],
          'sub'      => {
                          'name' => 'foo',
                          'message' => 'bar'
                        },
        );

And I want to turn it into something like this:

name=test+name&file_ids[]=1&file_ids[]=2&sub[name]=foo&sub[message]=bar

Even "data structure ==> JSON ==> query string" would be ok too.

I'm not finding any modules that do what I'm looking for. Does something like this exist?

Cheers,

Brent
