'field2' => [{'subfield1' => 'x', 'subfield2' => 'y'}, possibly more in array],
See HTTP::Request::Common, LWP doesn't accept/process hash refs , it doesn't have a concept of "subfields", like a regular html form its just key/value pairs. Specifically LWP* wants a flat list like this
[
'field1' => '1',
'field2{subfield1]' => 'x',
'field2[subfield2]' => 'y',
'field3{subfield3]' => 'int',
'field3{subfield4}' => 'string',
]
What you're looking for is like the opposite of CGI::Struct , it is PHP::HTTPBuildQuery / http_build_query
update: An example of a round trip with PHP::ParseStr/php_parse_str :)
update: and now with "LWP"
