Laravel中的API路由出错

Question

我在Laravel的API路由上遇到错误。我用过Dingo包。成功安装，在app.php中添加，由artisan生成api.php。

在路由器文件中，代码是： -

use Dingo\Api\Routing\Helpers;

$api = app('Dingo\Api\Routing\Router');
/*$api = app('Dingo\Api\Facade\Route');*/


$api->version('v1', function($api){
    $api->get('hello', function(){
        return "Hello !!!!!";
    });
});

在检查与php artisan api：routes时，我得到这样的路线/ api / routes /。但是，当我点击网址时，有一个很长的错误： -

Answer 1

我得到了答案。我在尝试使用localhost。我为API_DOMAIN和API_PREFIX提供了值。但是，必须知道在这种情况下不需要API_DOMAIN。
