WWW::Form::UrlEncoded - parser and builder for application/x-www-form-urlencoded
use WWW::Form::UrlEncoded qw/parse_urlencoded build_urlencoded/;
my $query_string = "foo=bar&baz=param";

WWW::Form::UrlEncoded provides application/x-www-form-urlencoded parser and builder. This module aims to have compatibility with other CPAN modules like HTTP::Body's urlencoded parser.
This module try to use WWW::Form::UrlEncoded::XS by default and fail to it, use WWW::Form::UrlEncoded::PP instead
WWW::Form::UrlEncoded parsed string in this rule.

-
@param = parse_urlencoded($str:String)
parse
$str
and return Array that contains key-value pairs. -
$param:ArrayRef = parse_urlencoded_arrayref($str:String)
parse
$str
and return ArrayRef that contains key-value pairs. -
$string = build_urlencoded(@param)
-
$string = build_urlencoded(@param, $delim)
-
$string = build_urlencoded(\@param)
-
$string = build_urlencoded(\@param, $delim)
-
$string = build_urlencoded(\%param)
-
$string = build_urlencoded(\%param, $delim)
build urlencoded string from param. build_urlencoded accepts arrayref and hashref values.
build_urlencoded( foo => 1, foo => 2); build_urlencoded( foo => [1,2] ); build_urlencoded( [ foo => 1, foo => 2 ] ); build_urlencoded( [foo => [1,2]] ); build_urlencoded( {foo => [1,2]} );
If
$delim
parameter is passed, this function use it instead of using&
. -
$string = build_urlencoded_utf8(...)
This function is almost same as
build_urlencoded
. build_urlencoded_utf8 callutf8::encode
for all parameters.
-
WWW_FORM_URLENCODED_PP
If true, WWW::Form::UrlEncoded force to load WWW::Form::UrlEncoded::PP.
CPAN already has some application/x-www-form-urlencoded parser modules like these.
They does not fully compatible with WWW::Form::UrlEncoded. Handling of empty key-value and supporting separator characters are different.
