php - Laravel https请求错误提示：Invalid request (Unsupported SSL request)

在LNMP环境中生成私有证书并配置nginx，我现在可以访问https://localhost

在laravel 路由中添加一条

Route::get('/ssl', array('https' => true, function() {
        return View('welcome');
    })
);

再启动laravel

php artisan serve

当我访问https://localhost:8000时并不成功
提示错误

我应该怎么做才能让https能够访问？
