laravel的跨域问题

大家好，我的前端是vue的，调用后端时涉及到跨域，在参考了这一篇之后，
博客：Laravel 跨域解决方案
我是这么写的，
1 新建一个中间件

php artisan make:middleware EnableCrossRequestMiddleware

2 书写中间件内容

<?php
namespace App\Http\Middleware;
use Closure;
class EnableCrossRequestMiddleware
{
    /**
     * Handle an incoming request.
     *
     * @param  \Illuminate\Http\Request $request
     * @param  \Closure $next
     * @return mixed
     */
    public function handle($request, Closure $next)
    {
        $response = $next($request);
        $origin = $request->server('HTTP_ORIGIN') ? $request->server('HTTP_ORIGIN') : '';
        $allow_origin = [
            'http://localhost:8081',
            'http://192.168.0.102:8081',
            'http://laraedu.yyii.info' 
        ];
        if (in_array($origin, $allow_origin)) {
            $response->header('Access-Control-Allow-Origin', $origin);
            $response->header('Access-Control-Allow-Headers', 'Origin, Content-Type, Cookie, X-CSRF-TOKEN, Accept, Authorization, X-XSRF-TOKEN');
            $response->header('Access-Control-Expose-Headers', 'Authorization, authenticated');
            $response->header('Access-Control-Allow-Methods', 'GET, POST, PATCH, PUT, OPTIONS');
            $response->header('Access-Control-Allow-Credentials', 'true');
        }
        return $response;
    }
}

3 然后在内核文件注册该中间件
在 App\Http\Kernel 类的 $middleware 属性添加，这里注册的中间件属于全局中间件

 protected $middlewareGroups = [
        'web' => [
            \App\Http\Middleware\EncryptCookies::class,
            \Illuminate\Cookie\Middleware\AddQueuedCookiesToResponse::class,
            \Illuminate\Session\Middleware\StartSession::class,
            // \Illuminate\Session\Middleware\AuthenticateSession::class,
            \Illuminate\View\Middleware\ShareErrorsFromSession::class,
            \App\Http\Middleware\VerifyCsrfToken::class,
            \Illuminate\Routing\Middleware\SubstituteBindings::class,
            \App\Http\Middleware\EnsureEmailIsVerified::class,      
        ],

        'api' => [
            \App\Http\Middleware\AcceptHeader::class,
            \App\Http\Middleware\EnableCrossRequestMiddleware::class, // <<--- 加这一行
            'throttle:60,1',
            'bindings',
        ],
    ];

然后本地调用，
首页没报跨域问题，登录时报跨域问题

线上，首页就报跨域问题，

如蒙指教，非常感谢！
