我尝试使用behaviors（）函数只允许索引操作，但现在它也被拒绝了

任何人都可以解决并解释规则返回。

<?php

namespace api\modules\v1\controllers;

use yii\rest\ActiveController;
use yii\filters\AccessControl;

/**
 * Doctor Controller API
 */
class DoctorController extends ActiveController
{
    public $modelClass = 'api\modules\v1\models\Doctor';

    public function behaviors()
    {
        return [
            'access' => [
                'class' => \yii\filters\AccessControl::className(),
                'only' => ['index'],
                'rules' => [
                    [
                        'allow' => false,
                        'verbs' => ['POST']
                    ],
                    [
                        'allow' => true,
                        'actions' => ['index'],
                        'verbs' => ['GET'],
                        'roles' => ['?'],
                    ],
                    [
                        'allow' => true,
                        'roles' => ['?'],
                    ],
                    // everything else is denied
                ],
            ],
        ];
    }
}
