Redirect to external URL with return in laravel

Question

I am trying to send one time password to a user using SMS INDIA HUB API. For that purpose I need to redirect to a URL format:

http://cloud.smsindiahub.in/vendorsms/pushs

Answer 1

For Laravel 5.x we can redirect with just

return redirect()->to($url);

Answer 2

Also, adding class

      use Illuminate\Http\RedirectResponse;

and after, like this:

 public function show($id){

    $link = Link::findOrFail($id);  // get data from db table Links

    return new RedirectResponse($link->url);  // and this my external link, 
 }

or -

 return  new RedirectResponse("http://www.google.com?andParams=yourParams"); 

For external links have to be used full URL string with 'http' in begin.
