请问下大哥，统一下单配置里 notify_url 设置了

            'body' => '加油',
            'detail' => '加油',
            'trade_type' => 'JSAPI',
            'out_trade_no' => $out_trade_no,
            'total_fee' => 1, // 单位：分
            'notify_url' => 'http://xxx.xxxx.com/weixin/notify-callback',
            //'attach' => '加油',
            'spbill_create_ip' => Yii::$app->request->getUserIP(),
            'openid' => $info->id,
            'sub_mch_id' => $merchant->weixinsellerid,
            //'sub_appid'=> Yii::$app->params['WECHAT']['app_id'],
        ];

然后在

 public function actionNotifyCallback()
    {
        $response = Yii::$app->wechat->payment->handleNotify(function ($notify, $successful) {
            // 使用通知里的 "微信支付订单号" 或者 "商户订单号" 去自己的数据库找到订单
            $order = MarketOrder::find()->where(['orderno' => $notify->out_trade_no])->one();
            if (!$order) { // 如果订单不存在
                return 'Order not exist.'; // 告诉微信，我已经处理完了，订单没找到，别再通知我了
            }
            // 如果订单存在
            // 检查订单是否已经更新过支付状态
            if ($order->status == 1) { // 假设订单字段“支付时间”不为空代表已经支付
                return true; // 已经支付成功了就不再更新了
            }
            // 用户是否支付成功
            if ($successful) {
                // 不是已经支付状态则修改为已经支付状态
                $order->create_at = time(); // 更新支付时间为当前时间
                $order->status = 1;
            } else { // 用户支付失败
                $order->status = 2;
            }
            $order->save(false); // 保存订单
            return true; // 返回处理完成
        });
        $response->send();
    }

为什不能通知，操作我后端相关业务
