93 | |
---|
94 | =head1 SYNOPSIS |
---|
95 | |
---|
96 | ## OO Interface |
---|
97 | use URI::Encode; |
---|
98 | my $uri = URI::Encode->new(); |
---|
99 | my $encoded = $uri->encode($url); |
---|
100 | my $decoded = $uri->decode($encoded); |
---|
101 | |
---|
102 | ## Using exported functions |
---|
103 | use URI::Encode qw(uri_encode uri_decode); |
---|
104 | my $encoded = uri_encode($url); |
---|
105 | my $decoded = uri_decode($url); |
---|
106 | |
---|
107 | =head1 DESCRIPTION |
---|
108 | |
---|
109 | This modules provides simple URI (Percent) encoding/decoding. This module |
---|
110 | borrows from L<URI::Escape>, but 'tinier' |
---|
111 | |
---|
112 | =head1 METHODS |
---|
113 | |
---|
114 | =head2 new() |
---|
115 | |
---|
116 | Creates a new object, no argumetns are required |
---|
117 | |
---|
118 | my $encoder = URI::Encode->new(); |
---|
119 | |
---|
120 | =head2 encode($url, $including_reserved) |
---|
121 | |
---|
122 | This method encodes the URL provided. The method does not encode any |
---|
123 | L</"Reserved Characters"> unless C<$including_reserved> is true. The $url |
---|
124 | provided is first converted into UTF-8 before percent encoding. |
---|
125 | |
---|
126 | $uri->encode("http://perl.com/foo bar"); # http://perl.com/foo%20bar |
---|
127 | $uri->encode("http://perl.com/foo bar", 1); # http%3A%2F%2Fperl.com%2Ffoo%20bar |
---|
128 | |
---|
129 | =head2 decode($url) |
---|
130 | |
---|
131 | This method decodes a 'percent' encoded URL. If you had encoded the URL using |
---|
132 | this module (or any other method), chances are that the URL was converted to |
---|
133 | UTF-8 before 'percent' encoding. Be sure to check the format and convert back |
---|
134 | if required. |
---|
135 | |
---|
136 | $uri->decode("http%3A%2F%2Fperl.com%2Ffoo%20bar"); # "http://perl.com/foo bar" |
---|

138 | =head1 EXPORTED FUNCTIONS |
---|
139 | |
---|
140 | The following functions are exported upon request. This provides a non-OOP |
---|
141 | interface |
