NAME

OpenInteract2::Response - Information about and actions on an HTTP response

SYNOPSIS

 # Normal usage

 use HTTP::Status qw( RC_OK );

 my $response = OpenInteract2::Response->get_current;
 $response->status( RC_OK );                 # default
 $response->content_type( 'text/html' )      # default
 $response->header( 'X-Powered-By' => 'OpenInteract 2.0' );
 my $cookie = CTX->cookie->create({ name    => 'session',
                                    expires => '+3d',
                                    value   => 'ISDFUASDFHSDAFUE' });
 $response->cookie( 'session', $cookie );

 # Sends the header (including cookies) and content to client

 $response->send;

PROPERTIES

All of the properties can be get and set by their name. For example:

 my $status = $response->status;          # Get the current status
 $response->status( RC_MAN_OVERBOARD );   # Set a new status

status - HTTP status of this response. If not set it will be set to RC_OK (from HTTP::Status) in the controller.

controller - The controller assigned to this response. This is useful for modifying the default template layout, setting the page title, etc. See OpenInteract2::Controller for more information.

return_url - A URL to which the user should return. This is useful for login boxes or other links that you don't want pointing to a particular place without first going through the correct path. For instance, returning from a '/Foo/edit/' you may want to set the return URL to '/Foo/show/' or something else harmless so you don't accidentally submit a new 'edit'. (Redirects are good for this, too.)

When set the response object ensures the given URL is located under the server context; therefore, the value returned from this property is always located under the server context.

send_file - Filename of file to send directly to the user. It is generally a good idea to set the 'Content-Type' header (via add_header()) when doing this.

content - Set the content for this response. Can be a scalar or a reference to a scalar, so the following will wind up displaying the same information:

 my $foo = "Fourscore and seven years ago...";
 $response->content( $foo );
 $response->content( \$foo );

SUBCLASSING

The actual work to send the correct data to the client is accomplished by a subclass of this class. Subclasses must do the following:

Implement init()
This method is called after the response is initialized. It must return the response object.
Implement get_current()
This must return the current response object
Implement clear_current()
This must remove any reference to the current response object. Successive calls to get_current() before the next response object is created must return undef.
Implement send()
This method will send the headers (including cookies) and content to the client. Note that the property content may be a scalar or a reference to a scalar: you will need to deal with both.
Implement redirect()
This should assemble headers appropriate to redirect the client to a new URL, which is passed as the first argument. Whether it actually sends the headers is another matter; most implementations will probably wait to send them until send() is called.
