The response object provides helper methods to inspect and interact with the underlying HTTP response.
The response object’s finalize() method returns a numeric array of [status, header, body]. The status is
an integer; the header is an iterable data structure; and the body is a string. Were you to create a new
\Slim\Http\Response object in your Slim application or its middleware, you would call the response object’s
finalize() method to produce the status, header, and body for the underlying HTTP response.
<?php
/**
* Prepare new response object
*/
$res = new \Slim\Http\Response();
$res->setStatus(400);
$res->write('You made a bad request');
$res->headers->set('Content-Type', 'text/plain');
/**
* Finalize
* @return [
* 200,
* ['Content-type' => 'text/plain'],
* 'You made a bad request'
* ]
*/
$array = $res->finalize();
The response object’s redirect() method will set the response status and its Location: header needed to
return a 3xx Redirect response.
<?php
$app->response->redirect('/foo', 303);
The response object provides other helper methods to inspect its current status. All the following methods return a boolean value:
<?php
$res = $app->response;
//Is this an informational response?
$res->isInformational();
//Is this a 200 OK response?
$res->isOk();
//Is this a 2xx successful response?
$res->isSuccessful();
//Is this a 3xx redirection response?
$res->isRedirection();
//Is this a specific redirect response? (301, 302, 303, 307)
$res->isRedirect();
//Is this a forbidden response?
$res->isForbidden();
//Is this a not found response?
$res->isNotFound();
//Is this a client error response?
$res->isClientError();
//Is this a server error response?
$res->isServerError();
