NAME¶
URI::data - URI that contains immediate data
SYNOPSIS¶
use URI;
$u = URI->new("data:");
$u->media_type("image/gif");
$u->data(scalar(`cat camel.gif`));
print "$u\n";
open(XV, "|xv -") and print XV $u->data;
DESCRIPTION¶
The "URI::data" class supports "URI" objects belonging to
the
data URI scheme. The
data URI scheme is specified in RFC
2397. It allows inclusion of small data items as "immediate" data,
as if it had been included externally. Examples:
data:,Perl%20is%20good
data:image/gif;base64,R0lGODdhIAAgAIAAAAAAAPj8+CwAAAAAI

"URI" objects belonging to the data scheme support the common methods
(described in URI) and the following two scheme-specific methods:
- $uri->media_type( [$new_media_type] )
- Can be used to get or set the media type specified in the
URI. If no media type is specified, then the default
"text/plain;charset=US-ASCII" is returned.
- $uri->data( [$new_data] )
- Can be used to get or set the data contained in the URI.
The data is passed unescaped (in binary form). The decision about whether
to base64 encode the data in the URI is taken automatically, based on the
encoding that produces the shorter URI string.
