Slim3 Response::withBody($string)

[rustyJ4ck]

Sending response with string body raise an error:

Catchable fatal error: Argument 1 passed to Slim\Http\Response::withBody() must implement interface Psr\Http\Message\StreamInterface, string given

From migration guide:

$app->get('/', function ($req, $res, $args) {
    return $res->withStatus(400)->withBody("Bad Request");
});

That should indeed be

// slim helper function
$res->write('Bad Request')

// psr7 proof
$res->getBody()->write('Bad Request')

// or a total new body
$res->withBody(new Body('Bad Request'))

Yep - the migration guide is wrong and needs to be updated. I'd love a PR that does this :)

@akrabat Which of the above versions would you like in the migration guide?

First one - it's not in middleware, so Slim specific is fine with me.
