Laravel 5.2 CORS，不要使用飞行前选项

Question

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

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;
    }

 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
    ];

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

 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
                        }
                )
            }
        }
    });

如果我取出授权头选项，请求就会工作。

我也试过https://github.com/barryvdh/laravel-cors，但仍然没有乐趣。任何帮助都很感激！

显然不是理想的解决方案，但它是有效的。我已经在routes.php文件的顶部添加了以下内容：

header('Access-Control-Allow-Origin: *');
header( 'Access-Control-Allow-Headers: Authorization, Content-Type' );

如果不用黑客就能工作就好了...唉。

更新：原来是IIS相关的。我最终在web.config文件中设置了头部，现在CORS不用攻击routes.php文件就可以工作了。

<httpProtocol>
    <customHeaders>
       <add name="Access-Control-Allow-Headers" value="Origin, Authorization, X-Requested-With, Content-Type, Accept" />
       <add name="Access-Control-Allow-Methods" value="POST,GET,OPTIONS,PUT,DELETE" />
    </customHeaders>
</httpProtocol>

      <outboundRules>
          <clear />
                <rule name="AddCrossDomainHeader">
                    <match serverVariable="RESPONSE_Access_Control_Allow_Origin" pattern=".*" />
                    <conditions logicalGrouping="MatchAll" trackAllCaptures="true">
                        <add input="{HTTP_ORIGIN}" pattern="(http(s)?://((.+\.)?somesite\.com|(.+\.)?anothersite\.org))" />
                    </conditions>
                    <action type="Rewrite" value="{C:0}" />
                </rule>
      </outboundRules>
