URI::data(3)                         User Contributed Perl Documentation                        URI::data(3)



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 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.
