Enable CORS via Middleware in Laravel

If you don’t have any idea what CORS is, then please skip this.

	<?php
	namespace App\Http\Middleware;
	use Closure;
	use Illuminate\Http\Response;
	class CORS
	{
	/**
	* Handle an incoming request.
	*
	* @param \Illuminate\Http\Request $request
	* @param \Closure $next
	* @return mixed
	*/
	public function handle($request, Closure $next)
	{
	$origin = request()->headers->get('origin', '*');
	$headers = [
	'Access-Control-Allow-Methods' => 'GET, PUT, POST, DELETE, OPTIONS',
	'Access-Control-Allow-Headers' => 'Content-Type, X-Auth-Token, Origin, Authorization, apitoken, ApiToken',
	'Access-Control-Allow-Origin' => $origin,
	'Access-Control-Allow-Credentials' => 'true',
	];
	if ($request->getMethod() == "OPTIONS") {
	return response('', 200)->withHeaders($headers);
	}
	$response = $next($request);
	foreach ($headers as $key => $value) {
	$response->header($key, $value);
	}
	return $response;
	}
	}
