android - 如何从 woocommerce Rest api 获取特定的 json 字段

Question

我已经使用 woocommerce Rest api 从我的 WordPress 网站获取了 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，name，slug)。

我搜索了很多问题，但没有明确的答案， 减少传入的json数据的目的是让应用程序运行得更快 更新 我已经尝试过没有 woocommerce Rest api

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

成功了 但不能像这样使用 woocommerce Rest api:

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

其实有办法，但是需要在woocommerce的functions.php中写一个hook；)

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，您要检索这些字段。

所以你在 woocommerce 中 Hook 了这种行为......类似的东西:

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;
}

还有...瞧

            }
        ],
        "collection": [
            {

            }
        ]
    }

            }
        ],
        "collection": [
            {
                "href": "http://localhost/wp-json/wc/v3/products"
            }
        ]
    }
},

                "href": "http://localhost/wp-json/wc/v3/products/35807"
            }
        ],
        "collection": [
            {
                "href": "http://localhost/wp-json/wc/v3/products"
            }
        ]
    }
},

...

希望这有帮助!顺便说一句，我设计了这个解决方案，深入阅读源代码。
