NAME

HTTP::Response::Encoding - Adds encoding() to HTTP::Response

VERSION

Version 0.02

SYNOPSIS

use LWP::UserAgent;
use HTTP::Response::Encoding;

my $ua = LWP::UserAgent->new();
my $res = $ua->get("http://www.example.com/");
warn $res->encoding;
print $res->decoded_content;

EXPORT

Nothing.

METHODS

This module adds the following methods to HTTP::Response objects.

$res->encoding

Tells the content encoding in the canonical name in Encode. Returns undef if it can't.

For most cases, you are more likely to successfully find encoding after GET than HEAD. HTTP::Response is smart enough to parse

<meta http-equiv="Content-Type" content="text/html; charset=whatever"/>

But you need the content to let HTTP::Response parse it. If you don't want to retrieve the whole content but interested in its encoding, try something like below;

my $req =  HTTP::Request->new(GET => $uri);
$req->headers->header(Range => "bytes=0-4095"); # just 1st 4k
my $res = $ua->request($req);
warn $res->encoding;
$res->decoded_content

Returns $res->content but decoded to Perl utf8 string.

Roughly equivalent to the code below.

Encode::decode($res->encoding, $res->content)

Note it croaks when $res->encoding is false. So you should check $res->encoding before using this method.

# i.e.
$content = $res->decoded_content if $res->encoding.

Also note that the meta tag remains intact.
