如何从 woocommerce rest API 获取特定的 json 字段

Question

我从我的WordPress网站上使用woocommercerest api获取了json数据，响应如下：

[{"id":4077,"name":"Work Benches","slug":"work-benches","parent":4076,"description":"","display":"default","image":null,"menu_order":0,"count":10,"_links":{"self":[{"href":"https://www.fynds.co.uk/wp-json/wc/v3/products/categories/4077"}],"collection":[{"href":"https://www.fynds.co.uk/wp-json/wc/v3/products/categories"}],"up":[{"href":"https://www.fynds.co.uk/wp-json/wc/v3/products/categories/4076"}]}},{"id":4802,"name":"Work Lights","slug":"work-lights","parent":4073,"description":"","display":"default","image":null,"menu_order":0,"count":23,"_links":{"self":[{"href":"https://www.fynds.co.uk/wp-json/wc/v3/products/categories/4802"}],"collection":[{"href":"https://www.fynds.co.uk/wp-json/wc/v3/products/categories"}],"up":[{"href":"https://www.fynds.co.uk/wp-json/wc/v3/products/categories/4073"}]}},{"id":4029,"name":"Work Safety Protective Equipment","slug":"work-safety-protective-equipment","parent":0,"description":"","display":"default","image":null,"menu_order":0,"count":53,"_links":{"self":[{"href":"https://www.fynds.co.uk/wp-json/wc/v3/products/categories/4029"}],"collection":[{"href":"https://www.fynds.co.uk/wp-json/wc/v3/products/categories"}]}},{"id":5248,"name":"Yoga & Pilates Blocks","slug":"yoga-pilates-blocks","parent":4296,"description":"","display":"default","image":null,"menu_order":0,"count":1,"_links":{"self":[{"href":"https://www.fynds.co.uk/wp-json/wc/v3/products/categories/5248"}],"collection":[{"href":"https://www.fynds.co.uk/wp-json/wc/v3/products/categories"}],"up":[{"href":"https://www.fynds.co.uk/wp-json/wc/v3/products/categories/4296"}]}},{"id":4556,"name":"Yoga & Pilates Mats","slug":"yoga-pilates-mats","parent":4296,"description":"","display":"default","image":null,"menu_order":0,"count":22,"_links":{"self":[{"href":"https://www.fynds.co.uk/wp-json/wc/v3/products/categories/4556"}],"collection":[{"href":"https://www.fynds.co.uk/wp-json/wc/v3/products/categories"}],"up":[{"href":"https://www.fynds.co.uk/wp-json/wc/v3/products/categories/4296"}]}}]

但是我只需要特定的属性，例如(id，名称，slug(。

我搜索了很多问题，但没有明确的答案，减少传入的 JSON 数据以使应用程序更快地工作的目的乌普特我试过 不呜 休息 API

https://*myweb*/wp-json/wp/v2/posts?filter[posts_per_page]=10&fields=id,title

成功了但是没有像这样使用woocommerce休息api：

https://www.***/wp-json/wc/v3/products?consumer_key=***&consumer_secret=****&per_page=10&field=id,name

Answer 1

其实有办法，但是你需要在 wooCommerce 中写一个钩子functions.php;)

假设以下 URL http://localhost/wp-json/wc/v3/products?fields=sku,name

诀窍是fields参数，它有一个逗号分隔的字段列表，您可以检索什么。

所以你在呜呜呜呜像这样：

add_filter( 'woocommerce_rest_prepare_product_object', 'my_woocommerce_rest_prepare_product_object', 10, 3 );
function my_woocommerce_rest_prepare_product_object( $response, $object, $request ) { 
    $data = $response->get_data();
    $newdata = [];
    foreach ( explode ( ",", $request['fields'] ) as $field ) {
        $newdata[$field] = $data[$field];
    }
    $response->set_data( $newdata );
    return $response;
}

和。。。瞧

 {
    "sku": "544392",
    "name": "ACIDET 3 EN 1 GALON",
    "_links": {
        "self": [
            {
                "href": "http://localhost/wp-json/wc/v3/products/35809"
            }
        ],
        "collection": [
            {
                "href": "http://localhost/wp-json/wc/v3/products"
            }
        ]
    }
},

    "sku": "544391",
    "name": "DESTAPADOR CANIERIA LEJIA GEL SELLO ROJOGL",
    "_links": {
        "self": [
            {
                "href": "http://localhost/wp-json/wc/v3/products/35808"
            }
        ],
        "collection": [
            {
                "href": "http://localhost/wp-json/wc/v3/products"
            }
        ]
    }
},
{
    "sku": "544389",
    "name": "ACIDET 3 EN 1 950ML",
    "_links": {
        "self": [
            {
                "href": "http://localhost/wp-json/wc/v3/products/35807"
            }
        ],
        "collection": [
            {
                "href": "http://localhost/wp-json/wc/v3/products"
            }
        ]
    }
},

。

希望这个帮助！！顺便说一句，我设计了这个解决方案，深入阅读了源代码。

我在 PazFernando 代码中添加了一个 IF，以防万一您可以在不指定字段的情况下发送 get 调用。

add_filter( 'woocommerce_rest_prepare_product_object', 'my_woocommerce_rest_prepare_product_object', 10, 3 );
function my_woocommerce_rest_prepare_product_object( $response, $object, $request ) 
{ 
   $data = $response->get_data();
   $newdata = [];
   if ($request['fields'] != null) 
   {
      foreach ( explode ( ",", $request['fields'] ) as $field ) 
      {
         $newdata[$field] = $data[$field];
      }
    
      $response->set_data( $newdata );
   }
   return $response;
}
