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
    AAgAAAClYyPqcu9AJyCjtIKc5w5xP14xgeO2tlY3nWcajmZZdeJcG

URI objects belonging to the data scheme support the common methods (described in the URI manpage) 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.
