61 Catalyst::Response - stores output responding to the current client request
68 $res->content_encoding;
81 This is the Catalyst Response class, which provides methods for responding to
82 the current client request. The appropriate L<Catalyst::Engine> for your environment
83 will turn the Catalyst::Response into a HTTP Response and return it to the client.
87 =head2 $res->body( $text | $fh | $iohandle_object )
89 $c->response->body('Catalyst rocks!');
91 Sets or returns the output (text or binary data). If you are returning a large body,
92 you might want to use a L<IO::Handle> type of object (Something that implements the read method
93 in the same fashion), or a filehandle GLOB. Catalyst
94 will write it piece by piece into the response.
98 Predicate which returns true when a body has been set.
102 Alias for $res->status.
104 =head2 $res->content_encoding
106 Shortcut for $res->headers->content_encoding.
108 =head2 $res->content_length
110 Shortcut for $res->headers->content_length.
112 =head2 $res->content_type
114 Shortcut for $res->headers->content_type.
116 This value is typically set by your view or plugin. For example,
117 L<Catalyst::Plugin::Static::Simple> will guess the mime type based on the file
118 it found, while L<Catalyst::View::TT> defaults to C<text/html>.
122 Returns a reference to a hash containing cookies to be set. The keys of the
123 hash are the cookies' names, and their corresponding values are hash
124 references used to construct a L<CGI::Simple::Cookie> object.
126 $c->response->cookies->{foo} = { value => '123' };
128 The keys of the hash reference on the right correspond to the L<CGI::Simple::Cookie>
129 parameters of the same name, except they are used without a leading dash.
130 Possible parameters are:
150 Shortcut for $res->headers->header.
154 Returns an L<HTTP::Headers> object, which can be used to set headers.
156 $c->response->headers->header( 'X-Catalyst' => $Catalyst::VERSION );
160 Alias for $res->body.
162 =head2 $res->redirect( $url, $status )
164 Causes the response to redirect to the specified URL. The default status is
167 $c->response->redirect( 'http://slashdot.org' );
168 $c->response->redirect( 'http://slashdot.org', 307 );
170 This is a convenience method that sets the Location header to the
171 redirect destination, and then sets the response status. You will
172 want to C< return > or C<< $c->detach() >> to interrupt the normal
173 processing flow if you want the redirect to occur straight away.
175 B<Note:> do not give a relative URL as $url, i.e: one that is not fully
176 qualified (= C<http://...>, etc.) or that starts with a slash
177 (= C</path/here>). While it may work, it is not guaranteed to do the right
178 thing and is not a standard behaviour. You may opt to use uri_for() or
179 uri_for_action() instead.
187 my $location = shift;
188 my $status = shift || 302;
190 $self->location($location);
191 $self->status($status);
194 return $self->location;
197 =head2 $res->location
199 Sets or returns the HTTP 'Location'.
203 Sets or returns the HTTP status.
205 $c->response->status(404);
207 $res->code is an alias for this, to match HTTP::Response->code.
209 =head2 $res->write( $data )
211 Writes $data to the output stream.
213 =head2 $res->print( @data )
215 Prints @data to the output stream, separated by $,. This lets you pass
216 the response object to functions that want to write to an L<IO::Handle>.
220 Ensures that the response is flushed and closed at the end of the
233 defined $self->write($data) or return;
236 defined $self->write($,) or return;
237 defined $self->write($_) or return;
239 defined $self->write($\) or return;
