Zend PSR7 does not work on Lumen?

Question

Zend PSR7 does not seem to work on Lumen:

use Psr\Http\Message\ServerRequestInterface;
use Zend\Diactoros\Response;

// PSR 7
$app->bind('Psr\Http\Message\ServerRequestInterface', function ($app) {
    return (new Symfony\Bridge\PsrHttpMessage\Factory\DiactorosFactory)->createRequest($app->make('request'));
});

// PSR 7.
$app->get('hello/{name}', function (ServerRequestInterface $request) {

    // Interact with the PSR-7 request
    $name = $request->getAttribute('name');

    // var_dump($request->getHeaders());
    var_dump($name); // get NULL instead of 'world'

    // Interact with the PSR-7 response
    $response = new Response();
    $response->getBody()->write('Hello, ' . $name);

    return $response->withHeader('Content-type', 'application/json');
});

First 'error':

var_dump($name); // get NULL instead of 'world'

Second ERROR:

UnexpectedValueException in Response.php line 395:
The Response content must be a string or object implementing __toString(), "object" given.
in Response.php line 395
at Response->setContent(object(Response)) in Response.php line 54

at Application->sendThroughPipeline(array(), object(Closure)) in Application.php line 1213
at Application->dispatch(object(Request)) in Application.php line 1153
at Application->run(object(Request)) in index.php line 28

Any ideas why?

Slim3 seems to be easier and more straight forward!

You can try my PSR HTTP library:

$response = new \Shieldon\Psr7\Response();

Kindly use this

use Laminas\Diactoros\Response as Psr7Response;

As Zend has been moved to Laminas, you can read more here.

Please explain your answer more inside your answer, as links will become non-functional over time. – Lajos Arpad Apr 01 '23 at 17:05
