Unable to redirect with status

Question

The controller is called using

$this->get( '/read/{slug}', \Rib\Src\Apps\Blog\BlogControllers\IndexController::class . ':index' );

Inside I tried:

return $response->withStatus( 404 )->withRedirect( '/message' );

or

return $response->withRedirect( '/message', 404 );

but the response returned always has a code of 200. How to enforce 404?

Answer 1

You cannot redirect the status code 404. For redirection valid only 3xx. When the browser receives the header Location:, it makes a new request to the given URL. This means that you can redirect the route that returns 404.

$app->get("/test", function ($request, $response, $arguments) {
    return $response->withRedirect("/message");
});

$app->get("/message", function ($request, $response, $arguments) {
    return $response->write("Oh noes!")->withStatus(404);
});

The above code will redirect you to a response with a status code 404.

$ curl --include --location http://0.0.0.0:8080/test
