Due to a security reasons browsers won't allow you to access other websites content until you specify with cors headers.
For more information on cors https://developer.mozilla.org/en-US/docs/Web/HTTP/CORS
Fix:
quick solution: in public/index.php add the following headers
header('Access-Control-Allow-Origin: *');
header('Access-Control-Allow-Methods: POST, GET, OPTIONS, PUT, DELETE');
header('Access-Control-Allow-Headers: Content-Type, X-Auth-Token, Origin, Authorization');
For better control and good practice use this package:

Hi, We used the command you shared but actually we faced the above issue only while connecting with web socket. Other than that we can be able to fetch the data. – Arun Pandian May 06 '19 at 07:45
