NAME
URI::Encode - Simple percent Encoding/Decoding
SYNOPSIS
# OOP Interface
use URI::Encode;
my $uri = URI::Encode->new( { encode_reserved => 0 } );
my $encoded = $uri->encode($data);
my $decoded = $uri->decode($encoded);
# Functional
use URI::Encode qw(uri_encode uri_decode);
my $encoded = uri_encode($data);
my $decoded = uri_decode($encoded);DESCRIPTION
This modules provides simple URI (Percent) encoding/decoding
The main purpose of this module (at least for me) was to provide an easy method to encode strings (mainly URLs) into a format which can be pasted into a plain text emails, and that those links are 'click-able' by the person reading that email. This can be accomplished by NOT encoding the reserved characters.
This module can also be useful when using HTTP::Tiny to ensure the URLs are properly escaped.
If you are looking for speed and want to encode reserved characters, use URI::Escape::XS
See this script for a comparison on encoding results and performance.
METHODS
new()
Creates a new object, no arguments are required
my $encoder = URI::Encode->new(\%options);The following options can be passed to the constructor
- encode_reserved
-
my $encoder = URI::Encode->new({encode_reserved => 0});If true, "Reserved Characters" are also encoded. Defaults to false.
- double_encode
-
my $encoder = URI::Encode->new({double_encode => 1});If false, characters that are already percent-encoded will not be encoded again. Defaults to true.
my $encoder = URI::Encode->new({double_encode => 0}); print $encoder->encode('http://perl.com/foo%20bar'); # prints http://perl.com/foo%20bar
encode($url, \%options)
This method encodes the URL provided. The $url provided is first converted into UTF-8 before percent encoding. Options set in the constructor, or defaults, can be overrided by passing them as the (optional) second argument. Options passed must be a hashref.
$uri->encode("http://perl.com/foo bar");
$uri->encode( "http://perl.com/foo bar", { encode_reserved => 1 } );decode($url)
This method decodes a 'percent' encoded URL. If you had encoded the URL using this module (or any other method), chances are that the URL was converted to UTF-8 before 'percent' encoding. Be sure to check the format and convert back if required.
$uri->decode("http%3A%2F%2Fperl.com%2Ffoo%20bar");EXPORTED FUNCTIONS
