If your Slim Framework application has a route that matches the current HTTP request URI but NOT the HTTP request method, the application invokes its Not Allowed handler and returns a HTTP/1.1 405 Not Allowed response to the HTTP client.
Each Slim Framework application has a default Not Allowed handler. This handler sets the Response status to 405, it sets the content type to text/html, it adds a Allowed: HTTP header with a comma-delimited list of allowed HTTP methods, and it writes a simple explanation to the Response body.
A Slim Framework application’s Not Allowed handler is a Pimple service. You can substitute your own Not Allowed handler by defining a custom Pimple factory method with the application container.
// Create Slim
$app = new \Slim\App();
// get the app's di-container
$c = $app->getContainer();
$c['notAllowedHandler'] = function ($c) {
return function ($request, $response, $methods) use ($c) {
return $c['response']
->withStatus(405)
->withHeader('Allow', implode(', ', $methods))
->withHeader('Content-type', 'text/html')
->write('Method must be one of: ' . implode(', ', $methods));
};
};N.B Check out Not Found docs for pre-slim creation method using a new instance of
\Slim\Container
In this example, we define a new notAllowedHandler factory that returns a callable. The returned callable accepts three arguments:
\Psr\Http\Message\ServerRequestInterface instance\Psr\Http\Message\ResponseInterface instanceThe callable MUST return an appropriate \Psr\Http\Message\ResponseInterface instance.
