How to define content-type with Code Igniter REST_Controller
I'm not sure if the config sets the format. But a simple work around might be just to use the output class to set the header content type, something like:
$this->output ->set_content_type('application/json') ->set_output(json_encode(array('foo' => 'bar')));(Taken from the manual: here)
While setting contect_type at each functions helps, this can be made generic at controller level by setting this at constructor.
public function __construct() { parent::__construct(); ... $this->output->set_content_type('application/json');}So you would simply set the output at each function level
$this->output->set_output('{"message":"Failure"}');This worked for me.
