I normally just use Laravel Cors for this.
It allows you to set up different cors settings for different paths in a configuration file.

Yeah, I gave up on doing this this way, because it does not work and I have spend too much time trying to figure it.
laravel-cors
solved my problem.
Can you show me your laravel-cors configuration, because it still doesn't work for me.
Please create an issue on Github if it doesn't work.
I am using Laravel 5.4 and didn't want to use a package so ended up writing my own middleware. The code looks like this:
<?php
namespace App\Http\Middleware;
use Closure;
class Cors
{
private static $allowedOriginsWhitelist = [
'http://localhost:8000'
];
// All the headers must be a string
private static $allowedOrigin = '*';
private static $allowedMethods = 'OPTIONS, GET, POST, PUT, PATCH, DELETE';
private static $allowCredentials = 'true';
private static $allowedHeaders = '';
/**
* Handle an incoming request.
*
* @param \Illuminate\Http\Request $request
* @param \Closure $next
* @return mixed
*/
public function handle($request, Closure $next)
{
if (! $this->isCorsRequest($request))
{
return $next($request);
}
static::$allowedOrigin = $this->resolveAllowedOrigin($request);
static::$allowedHeaders = $this->resolveAllowedHeaders($request);
$headers = [
'Access-Control-Allow-Origin' => static::$allowedOrigin,
'Access-Control-Allow-Methods' => static::$allowedMethods,
'Access-Control-Allow-Headers' => static::$allowedHeaders,
'Access-Control-Allow-Credentials' => static::$allowCredentials,
];
// For preflighted requests
if ($request->getMethod() === 'OPTIONS')
{
return response('', 200)->withHeaders($headers);
}
$response = $next($request)->withHeaders($headers);
return $response;
}
/**
* Incoming request is a CORS request if the Origin
* header is set and Origin !== Host
*
* @param \Illuminate\Http\Request $request
*/
private function isCorsRequest($request)
{
$requestHasOrigin = $request->headers->has('Origin');
if ($requestHasOrigin)
{
$origin = $request->headers->get('Origin');
$host = $request->getSchemeAndHttpHost();
if ($origin !== $host)
{
return true;
}
}
return false;
}
/**
* Dynamic resolution of allowed origin since we can't
* pass multiple domains to the header. The appropriate
* domain is set in the Access-Control-Allow-Origin header
* only if it is present in the whitelist.
*
* @param \Illuminate\Http\Request $request
*/
private function resolveAllowedOrigin($request)
{
$allowedOrigin = static::$allowedOrigin;
// If origin is in our $allowedOriginsWhitelist
// then we send that in Access-Control-Allow-Origin
$origin = $request->headers->get('Origin');
if (in_array($origin, static::$allowedOriginsWhitelist))
{
$allowedOrigin = $origin;
}
return $allowedOrigin;
}
/**
* Take the incoming client request headers
* and return. Will be used to pass in Access-Control-Allow-Headers
*
* @param \Illuminate\Http\Request $request
*/
private function resolveAllowedHeaders($request)
{
$allowedHeaders = $request->headers->get('Access-Control-Request-Headers');
return $allowedHeaders;
}
}
Then put this middleware in app/Http/Kernel.php
:
protected $middleware = [
// Other middleware classes ...
\App\Http\Middleware\Cors::class,
];
