Response::json() - Laravel 5.1

use the helper function in laravel 5.1 instead:

return response()->json(['name' => 'Abigail', 'state' => 'CA']);

This will create an instance of \Illuminate\Routing\ResponseFactory. See the phpDocs for possible parameters below:

/**
* Return a new JSON response from the application.
*
* @param string|array $data
* @param int $status
* @param array $headers
* @param int $options
* @return \Symfony\Component\HttpFoundation\Response 
* @static 
*/
public static function json($data = array(), $status = 200, $headers = array(), $options = 0){

    return \Illuminate\Routing\ResponseFactory::json($data, $status, $headers, $options);
}

After enough googling I found the answer from controller you need only a backslash like return \Response::json(['success' => 'hi, atiq']); . Or you can just return the array return array('success' => 'hi, atiq'); which will be rendered as json in Laravel version 5.2 .

You need to add use Response; facade in header at your file.

Only then you can successfully retrieve your data with

return Response::json($data);
