Follow this section of the book: http://book.cakephp.org/3.0/en/views/json-and-xml-views.html and don’t forget to enable http://book.cakephp.org/3.0/en/development/routing.html#file-extensions

After that access your controller action with .json in the url. For example: $controller/teste.json

I believe this is more like you want:

    $this->RequestHandler->respondAs('json');
    $this->response->type('application/json');  
    $this->autoRender = false; 
    echo json_encode($any_content);
