=head1 NAME
Catalyst::Response - stores output responding to the current client request
=head1 SYNOPSIS
$res = $c->response;
$res->body;
$res->code;
$res->content_encoding;
$res->content_length;
$res->content_type;
$res->cookies;
$res->header;
$res->headers;
$res->output;
$res->redirect;
$res->status;
$res->write;
=head1 DESCRIPTION
This is the Catalyst Response class, which provides methods for responding to
the current client request. The appropriate L<Catalyst::Engine> for your environment
will turn the Catalyst::Response into a HTTP Response and return it to the client.
=head1 METHODS
=head2 $res->body( $text | $fh | $iohandle_object )
$c->response->body('Catalyst rocks!');
Sets or returns the output (text or binary data). If you are returning a large body,
you might want to use a L<IO::Handle> type of object (Something that implements the read method
in the same fashion), or a filehandle GLOB. Catalyst
will write it piece by piece into the response.
=head2 $res->has_body
Predicate which returns true when a body has been set.
=head2 $res->code
Alias for $res->status.
=head2 $res->content_encoding
Shortcut for $res->headers->content_encoding.
=head2 $res->content_length
Shortcut for $res->headers->content_length.
=head2 $res->content_type
Shortcut for $res->headers->content_type.
This value is typically set by your view or plugin. For example,
L<Catalyst::Plugin::Static::Simple> will guess the mime type based on the file
it found, while L<Catalyst::View::TT> defaults to C<text/html>.
=head2 $res->cookies
Returns a reference to a hash containing cookies to be set. The keys of the
hash are the cookies' names, and their corresponding values are hash
references used to construct a L<CGI::Simple::Cookie> object.
$c->response->cookies->{foo} = { value => '123' };
The keys of the hash reference on the right correspond to the L<CGI::Simple::Cookie>
parameters of the same name, except they are used without a leading dash.
Possible parameters are:
=over
=item value
=item expires
=item domain
=item path
=item secure
=item httponly
=back
=head2 $res->header
Shortcut for $res->headers->header.
=head2 $res->headers
Returns an L<HTTP::Headers> object, which can be used to set headers.
$c->response->headers->header( 'X-Catalyst' => $Catalyst::VERSION );
=head2 $res->output
Alias for $res->body.
=head2 $res->redirect( $url, $status )
Causes the response to redirect to the specified URL. The default status is
C<302>.
$c->response->redirect( 'http://slashdot.org' );
$c->response->redirect( 'http://slashdot.org', 307 );
This is a convenience method that sets the Location header to the
redirect destination, and then sets the response status. You will
want to C< return > or C<< $c->detach() >> to interrupt the normal
processing flow if you want the redirect to occur straight away.
B<Note:> do not give a relative URL as $url, i.e: one that is not fully
qualified (= C<http://...>, etc.) or that starts with a slash
(= C</path/here>). While it may work, it is not guaranteed to do the right
thing and is not a standard behaviour. You may opt to use uri_for() or
uri_for_action() instead.
=cut
sub redirect {
my $self = shift;
if (@_) {
my $location = shift;
my $status = shift || 302;
$self->location($location);
$self->status($status);
}
return $self->location;
}
=head2 $res->location
Sets or returns the HTTP 'Location'.
=head2 $res->status
Sets or returns the HTTP status.
$c->response->status(404);
$res->code is an alias for this, to match HTTP::Response->code.
=head2 $res->write( $data )
Writes $data to the output stream.
=head2 $res->print( @data )
Prints @data to the output stream, separated by $,. This lets you pass
the response object to functions that want to write to an L<IO::Handle>.
=head2 $self->finalize_headers($c)
Writes headers to response if not already written
=head2 DEMOLISH
Ensures that the response is flushed and closed at the end of the
request.
