I already solved this situation in PHP Model Relationship And Thanks!

public function getExchangeGoodsList() {
    $gameGoodsConfigModel = new GameGoodsConfigModel();
    $config = $gameGoodsConfigModel::all();
    $goodsExchangeRuleList = [];
    foreach ($config as $key => $obj) {
        $itemArr = module_to_array($obj);
        $itemArr['pay_goods'] = module_to_array($obj->goods);
        $itemArr['goal_goods'] = module_to_array($obj->goalGoods);
        array_push($goodsExchangeRuleList, $itemArr);
    }
}
