如果你要設定一支 API 是可以跨網域存取的，在 Laravel 11.x（好像是 9.x 之後版本就可以了），可以用以下方法：
首先生成 config/cors.php 的檔案
php artisan config:publish cors
裡面大概會長這樣：
return [
/*
|--------------------------------------------------------------------------
| Cross-Origin Resource Sharing (CORS) Configuration
|--------------------------------------------------------------------------
|
| Here you may configure your settings for cross-origin resource sharing
| or "CORS". This determines what cross-origin operations may execute
| in web browsers. You are free to adjust these settings as needed.

*/
'paths' => ['api/*', 'sanctum/csrf-cookie'],
'allowed_methods' => ['*'],
'allowed_origins' => ['*'],
'allowed_origins_patterns' => [],
'allowed_headers' => ['*'],
'exposed_headers' => [],
'max_age' => 0,
'supports_credentials' => false,
];
再把 allowed_origins 改成要可以存取的網域就可以了，可以使用正規表達式定義規則，比如我要讓我 wingzero.tw 下的子網域都可以，就可以這樣寫：
'allowed_origins_patterns' => [
'~^https://.*\.wingzero\.tw$~',
'~^https://wingzero\.tw$~',
],
給大家參考。
