【问题描述】：

有没有办法重新加入嵌套字段，因为作为响应，它会分解成单独的对象。

实际反应：

{"id":"gid:\/\/shopify\/Product\/1755556806746","title":"A Book bind","description":"Energize is a pure Sativa formulation designed to stimulate, excite, and keep you productive","productType":"CARTRIDGE","vendor":"ACES","totalInventory":0,"featuredImage":null,"handle":"1g-energizedurban-cart-82-89"}
{"id":"gid:\/\/shopify\/Metafield\/4680431861850","namespace":"custom_fields","key":"thc_percentage","value":"aa","__parentId":"gid:\/\/shopify\/Product\/1755556806746"}
{"id":"gid:\/\/shopify\/Metafield\/4680431894618","namespace":"custom_fields","key":"cbd_percentage","value":"bb","__parentId":"gid:\/\/shopify\/Product\/1755556806746"}
{"id":"gid:\/\/shopify\/Metafield\/4680431960154","namespace":"custom_fields","key":"strain_name","value":"Strain","__parentId":"gid:\/\/shopify\/Product\/1755556806746"}

预期响应：

{"id":"gid:\/\/shopify\/Product\/1755556806746","title":"A Book bind","description":"Energize is a pure Sativa formulation designed to stimulate, excite, and keep you productive","productType":"CARTRIDGE","vendor":"ACES","totalInventory":0,"featuredImage":null,"handle":"1g-energizedurban-cart-82-89",
metafields:[{"id":"gid:\/\/shopify\/Metafield\/4680431861850","namespace":"custom_fields","key":"thc_percentage","value":"aa","__parentId":"gid:\/\/shopify\/Product\/1755556806746"},
{"id":"gid:\/\/shopify\/Metafield\/4680431894618","namespace":"custom_fields","key":"cbd_percentage","value":"bb","__parentId":"gid:\/\/shopify\/Product\/1755556806746"},

【解决方案1】：

Shopify 使用 JSON Lines (JSONL) 数据类型来输出批量操作的响应。

文件中的每一行都是连接中返回的一个节点对象。如果一个节点有一个嵌套连接，然后将每个子节点提取到下一行是它自己的对象。

因此，您需要遍历每一行并将其解析为脚本中的 JSON 对象。使用 __parentId 属性作为对父对象的引用。
如果需要，将其加入父对象，但您只能在收到响应后执行此操作。您不能强制 Shopify API 为您执行此操作。
