laravel cors“类cors不存在”错误

Question

我遵循https://github.com/barryvdh/laravel-cors在我的应用程序上启用了CORS。

当我刷新我的页面(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中包含以下代码行

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

Routes.php

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

我猜在某个地方我需要调用这个包，比如使用包etc..but我找不到任何结果来帮助我解决问题。

请帮帮忙。

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上的readme.md缺少了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" or copy vendor/barryvdh/laravel-cors/config/cors.php to Barryvdh\Cors\ServiceProvider::class
• app/Http/Kernel.php -> 'providers'：config/cors.php
• config/app.php -> $routeMiddleware：

(<-如果需要)

现在cors中间件将为您的路由工作：

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

Answer 3

只需在app/Http/kernel.php中从受保护的$middlewareGroups中删除cors
