如何将产品类别添加到每个line_items woocomerce rest api

Question

使用当前的Woocommerce文档，我可以从网站上的woocommerce检索所有订单。

"line_items" => array:2 [▼
0 => array:14 [▼
  "id" => 1
  "name" => "Multi Tool"
  "product_id" => 227
  "variation_id" => 0
  "quantity" => 1
  "tax_class" => ""
  "subtotal" => "15.00"
  "subtotal_tax" => "0.00"
  "total" => "15.00"
  "total_tax" => "0.00"
  "taxes" => []
  "meta_data" => []
  "sku" => ""
  "price" => 15
]
1 => array:14 [▶]

问题是，api没有为每个产品提供类别，它只响应line_items下的product_ id。有没有我可以在每个产品下添加一个自定义字段，名为类别，每个产品的类别名称？

您必须使用以下过滤器更改Orders API的响应。

add_filter( 'woocommerce_rest_prepare_shop_order_object', 
'custom_change_shop_order_response', 20, 3 );
function custom_change_shop_order_response( $response, $object, $request ) {
//here you can customize the product response of the order
}
