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

The following functions are exported upon request. This provides a non-OOP interface

uri_encode($url, \%options)
uri_decode($url)

CHARACTER CLASSES

Reserved Characters

The following characters are considered as reserved (RFC 3986). They will be encoded only if requested.

         ! * ' ( ) ; : @ & = + $ , / ? # [ ]

Unreserved Characters

The following characters are considered as Unreserved. They will not be encoded

        a-z
        A-Z
        0-9
        - _ . ~
