perl - decode form-urlencoded to hash

Question

The response I get to an LWP request is application/x-www-form-urlencoded is it possible convert the text of this to a hash via some object method?

Answer 1

# from a HTTP::Response object
my $urlencoded = $response->content;

1. VarsinCGI返回一个哈希值。

   use CGI qw();
   CGI->new($urlencoded)->Vars;
   

2. parametersinPlack::Request返回一个Hash::MultiValue对象，它实际上是适合此的数据结构。

   use Plack::Request qw();
   Plack::Request->new({QUERY_STRING => $urlencoded})->parameters;
   

3. paramin APR::Request/libapreq2 - 不完全是 Perl 哈希，而是带有附加 Magic 的 XS 对象，其行为足够接近。

   insert hand-waving here, no libapreq2 available right now for testing
   

4. url_params_mixed在URL::Encode

   require URL::Encode::XS;
   use URL::Encode qw(url_params_mixed);
   url_params_mixed $urlencoded;
   

5. parse_query_string在CGI::Deurl::XS

   use CGI::Deurl::XS 'parse_query_string';
   parse_query_string $urlencoded;
   

6. query_form在URI紧要关头，in 也很好用；query_form_hash在URI::QueryParam. _

   use URI qw();
   URI->new("?$urlencoded")->query_form;
   
   use URI::QueryParam qw();
   URI->new("?$urlencoded")->query_form_hash;
