如何从 WC API 端点请求中删除数据？

Question

我正在将订单数据发送到第三方履行软件。它们默认与 WooCommerce REST API 集成。但是，最近对我的网站和订单数据的一些更改添加了额外的订单元数据。现在，当抓取相同数量的订单时，请求总是以 504 超时。请求现在大得不合理，为了解决这个问题，我决定通过减少请求产生的不相关和不必要的数据来进行优化。此外，我必须能够一次处理 100 个，我不能减少过滤器限制，它由 3rd 方应用程序自动设置。

问题中的端点

wc-api/v2/orders?status=processing&page=1&filter%5Blimit%5D=100

此端点抓取前 100 个正在处理的订单并将它们显示为一段 JSON。

要删除的内容

1. customer_user_agent
2. 头像_url
3. cogs_cost
4. cogs_total_cost

这是我得到的最远的

我找到了以下钩子，但无法触发任何东西。

woocommerce_rest_prepare_shop_order_object
woocommerce_rest_prepare_shop_order

function remove_user_agent_from_rest_api( $response, $object, $request ) {
    unset($response->data['customer_user_agent']);
    return $response;
}

function test_rest_api() {
add_filter( "woocommerce_rest_pre_insert_shop_order", "remove_user_agent_from_rest_api", 10, 2 );
add_filter( "woocommerce_rest_pre_insert_shop_order_object", "remove_user_agent_from_rest_api", 10, 2 );
}

add_action( 'rest_api_init', 'test_rest_api', 0 );

这是性能调整问题吗？

这是来自 new relic 的示例跟踪和来自我的 NGINX 错误日志的示例。我可以调整什么来让服务器保持足够长的时间来处理这个请求。

Answer 1

我注意到第一个问题是您的过滤器只传递了 2 个变量，而它们应该传递 3 个。

add_filter( "woocommerce_rest_pre_insert_shop_order", "remove_user_agent_from_rest_api", 10, 3 );

应该这样做。
