子域名上Laravel10的CORS出现问题

主要原因是当前的浏览器符合同源策略，不允许跨域访问资源，因此需要设置CORS。可通过在Laravel项目的中间件(Middleware)中引入barryvdh/laravel-cors包来解决此问题。以下是代码示例：

1.安装barryvdh/laravel-cors：

composer require barryvdh/laravel-cors

2.在app/Http/Kernel.php的$middlewareGroups中，添加以下代码：

'cors' => \Barryvdh\Cors\HandleCors::class,

3.在需要设置CORS的路由中，添加以下代码：

Route::middleware('cors')->group(function () { // your routes here });

或者，你也可以在所有路由中启用CORS，只需要在$middlewareGroups中将全局中间件\Barryvdh\Cors\HandleCors::class添加到web组中：

protected $middlewareGroups = [ 'web' => [ // ... \Barryvdh\Cors\HandleCors::class, ],

    'api' => [
        \Barryvdh\Cors\HandleCors::class,
        'throttle:60,1',
        \Illuminate\Routing\Middleware\SubstituteBindings::class,
    ],
];

4.在config/cors.php中，进行CORS参数的设置：

return [

/*
|--------------------------------------------------------------------------
| Laravel CORS Options
|--------------------------------------------------------------------------
|
| The allowed_methods and allowed_headers options are case-insensitive.
|
 */

'allowed_origins' => ['*'],

'allowed_origins_patterns' => [],

'allowed_headers' => ['*'],

'allowed_methods' => ['*'],

'exposed_headers' => [],

'max_age' => 0,

'supports_credentials' => false,

];

以上操作完成后，就可以愉快地在子域名上使用Laravel 10了！
