Php 控制器功能在yii2中不工作

我是Yii的新手，我被以下问题困扰着。下面是我编写的一个简单代码，用于搜索给定ID并将关联的表行返回给用户。

use yii\rest\ActiveController;
use yii\web\Response;
use common\models\Restaurant;
use common\models\Address;

class DeliveryCostController extends ActiveController{

public $modelClass = 'common\models\Restaurant';


public function actionGetFixedCost($restaurantID = NULL){

    $restaurant = Restaurant::findOne(['id'=>$restaurantID]);
    if ($restaurant !== null) {
        return [
            'restaurant ID' => $restaurant['id'],
            'restaurant Name' => $restaurant['name'],
            'Fixed Delivery Cost' => $restaurant['fixed_delivery_cost']
        ];
    }else{
        return [
            'Status' => 'Failed',
            'Message' => 'Restaurant with ID ' . $restaurantID.' Not Found'
        ];
    }
}
}
?>

我尝试通过以下方式访问此控制器：

http://localhost/food/api/web/deliverycost/getFixedCost?restaurantID=24

但我得到了以下错误页面

    An Error occurred while handling another error:
    yii\base\InvalidRouteException: Unable to resolve the request "site/error". in C:\xampp\htdocs\food\vendor\yiisoft\yii2\base\Module.php:532

根据Yii2 ruoting惯例规则，您应该使用“获取固定成本”

PS与站点/控制器相关的消息i中的错误

检查站点/控制器中是否也有此代码

/**
 * @inheritdoc
 */
public function actions()
{
    return [
        'error' => [
            'class' => 'yii\web\ErrorAction',
        ],
    ];
}

---

请更新您的问题并添加相关的url调用，同时显示您的站点控制器code@scaisEdge做到了

/**
 * @inheritdoc
 */
public function actions()
{
    return [
        'error' => [
            'class' => 'yii\web\ErrorAction',
        ],
    ];
}
