laravel cors“类cors不存在”错误

Question

我已经关注https://github.com/barryvdh/laravel-cors在我的应用程序上启用CORS。

当我刷新页面（REST端点）时，我收到以下消息： -

Class cors does not exist

我运行了以下命令： -

composer require barryvdh/laravel-cors 0.7.x

并在我的composer.json中有以下行

"barryvdh/laravel-cors": "0.7.x"

routes.php文件

Route::group(['middleware' => 'cors'], function($router){
    $router->get('names/{id}', 'NameController@showEmpDetail');
    $router->resource('names', 'NameController');
});

我猜这个地方我需要调用包，比如使用包等等。但是我找不到任何结果来帮助我。

请帮忙。

谢谢

Answer 1

尝试添加

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

至

 /app/Http/Kernel.php $routeMiddleware

Answer 2

https://github.com/barryvdh/laravel-cors的readme.md缺少Laravel 5的几个步骤。以下是完整的说明：

• composer require barryvdh/laravel-cors 0.7.x
• php artisan vendor:publish --provider="Barryvdh\Cors\ServiceProvider"或复制vendor/barryvdh/laravel-cors/config/cors.php到config/cors.php
• config / app.php - >'providers'：Barryvdh\Cors\ServiceProvider::class
• app / Http / Kernel.php - > $ routeMiddleware：'cors' => \Barryvdh\Cors\Middleware\HandleCors::class
• php artisan cache:clear（

现在，cors中间件将适用于您的路由：

Route::group(['middleware' => 'cors'], function(Router $router){
    $router->get('api', 'ApiController@index'); // <- your route here
});

Answer 3

您需要在终端中运行此命令

php artisan vendor:publish --provider="Barryvdh\Cors\ServiceProvider"

Answer 4

更改app \ Providers \ RouteServiceProvider.php中的mapApiRoutes（）方法，不要将'cors'放在前缀函数中，只需将'api'作为参数

protected function mapApiRoutes()
{
    Route::prefix('api')
         ->middleware('api')
         ->namespace($this->namespace)
         ->group(base_path('routes/api.php'));
}
