Laravel 5.2 CORS，GET无法与预检选项一起使用

可怕的CORS错误：

跨域请求被阻止：同源策略禁止读取http：// localhost / mysite / api / test上的远程资源。（原因：CORS标头“ Access-Control-Allow-Origin”缺失）。

Laravel路线：

$router->group(['prefix' => 'api', 'middleware' => 'cors'], function ($router) {
    $router->get('/test', 'MyController@myMethod');
});

Laravel Cors Middlware：

public function handle($request, Closure $next)
    {
        header('Access-Control-Allow-Origin: *');

        // ALLOW OPTIONS METHOD
        $headers = [
            'Access-Control-Allow-Methods' => 'POST, GET, OPTIONS, PUT, DELETE',
            'Access-Control-Allow-Headers' => 'Content-Type, X-Auth-Token, Origin, Authorization'
        ];
        if ($request->getMethod() == "OPTIONS") {
            // The client-side application can set only headers allowed in Access-Control-Allow-Headers
            return Response::make('OK', 200, $headers);
        }

        $response = $next($request);
        foreach ($headers as $key => $value)
            $response->header($key, $value);
        return $response;
    }

Laravel内核：

 protected $routeMiddleware = [
        'auth' => \App\Http\Middleware\Authenticate::class,
        'auth.basic' => \Illuminate\Auth\Middleware\AuthenticateWithBasicAuth::class,
        'guest' => \App\Http\Middleware\RedirectIfAuthenticated::class,
        'throttle' => \Illuminate\Routing\Middleware\ThrottleRequests::class,
        'cors' => \App\Http\Middleware\CORS::class
    ];

相关的.htaccess：

RewriteCond %{HTTP:Authorization} .
RewriteRule .* - [E=HTTP_AUTHORIZATION:%{HTTP:Authorization}]

相关的Vue.js：

 new Vue({
        el: '#app',
        data: {
           //data here
        },
        http: {
            headers: {
                "Authorization": "Basic " + "apiKeyHere"
            }
        },
        methods: {
            mymethod: function (e)
            {
                e.preventDefault();
                this.$http.get('http://localhost/mysite/api/test').then(
                        function (response)
                        {
                          //do something
                        }
                )
            }
        }
    });

如果我取出Authorization标头选项，则请求有效。

我也尝试过https://github.com/barryvdh/laravel-cors，但仍然没有任何乐趣。任何帮助表示赞赏！
