最近Shopify发布了一种前往retrieving metafields with the Storefront API 的方法。为了获得对Shopify GraphQL Storefront API中的元字段的读取访问权限，我们必须将Shopify GraphQL Admin API中的元字段列入白名单。

我创建了2个本地插件：

gatsby-source-shopify-metafields，它使用graphql-request到产品上的确切元字段的updateMetafieldStorefrontVisibility。要进行updateMetafieldStorefrontVisibility突变，请执行cd plugins/gatsby-source-shopify-metafields && node lib.js。
gatsby-source-shopify是default gatsby-source-shopify插件的更新版本，其中编辑了queries.js，nodes.js和gatsby-node.js文件，以包含新可用的metafields字段。

运行updateMetafieldStorefrontVisibility之后，我可以使用curl查询产品元字段：

curl -X POST \
"https://shop-name.myshopify.com/api/graphql.json" \
-H "Content-Type: application/graphql" \
-H "X-Shopify-Storefront-Access-Token: XXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX" \
-d '
query {
  productByHandle(handle: "nike-air-max-720") {
    metafield(namespace: "global", key: "free_shipping") {
      value
    }
  }
}
'

响应：{"data":{"productByHandle":{"metafield":{"value":"true"}}}}
