Phalcon routing correctly pattern

Help with routing settings, there is the following request template with frontend: /books/([0-9]+)/book-authors/([0-9]+)/images

There is a controller located in namespace: Shop\Controllers\Books\BookAuthors\ImagesController

The controller has an indexAction method.

In routing.php I specify the following:

$router = new Router(false);

$router->removeExtraSlashes(true);
$router->setDefaultNamespace('Shop\Controllers');
$router->setDefaultController('index');
$router->setDefaultAction('index');

$router->addGet('/books/([0-9]+)/book-authors/([0-9]+)/images', [
     'namespace' => 'Shop\Controllers\Books\BookAuthors',
     'bookId' => 1,
     'authorId' => 2,
     'controller' => 'images',
     'action' => 'index',
]);
return $router;

As a result, we get that the redirect always goes to the default controller. Please tell me how to fix...

I tried to debug and check why the template does not fit, but when I checked regex101 on the site, everything matches there and should work, but for some reason it does not work in phalcon. Application return every time "not found"

Solution

The route works fine, although you can try this for simplicity and clarity:

$router->addGet('/books/{bookId:[0-9]+}/book-authors/{authorId:[0-9]+}/images', 
 [
   'controller' => 'images',
   'action'     => 'index'
 ]
);

And in your ImagesController define indexAction as:

public function indexAction(int $bookId, int $authorId)
{
    echo "BookId: $bookId and AuthorId: $authorId";
}

For /books/10/book-authors/22/images the result should be:

BookId: 10 and AuthorId: 22
