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.
    |
    | To learn more: https://developer.mozilla.org/en-US/docs/Web/HTTP/CORS
    |
    */

    '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。
