WooCommerce

使用 WooCommerce 扩展，我们可以通过 GraphQL 获取 WooCommerce 商品数据。

WooCommerce 商品类型

字段 woocommerceProducts 返回 WooCommerceProductUnion 类型，由 4 种可能的商品类型组成：

WooCommerceSimpleProduct
WooCommerceExternalProduct
WooCommerceGroupProduct
WooCommerceVariableProduct

根据各类型的不同，可查询的字段也会有所差异。

WooCommerce 商品接口

由于 2 种不同的商品类型（以及商品变体）可能共享某些字段，这些字段被添加到各商品类型可以选择实现的接口中。

例如，Shippable 适用于支持配送的商品，Priceable 适用于有价格的商品（变体商品没有 price 字段，由其变体提供），Taxable 适用于支持税务设置的商品，以此类推。

接口	说明
`WooCommerceProduct`	所有商品类型共享的字段（即由全部 4 种类型实现）
`WooCommerceProductOrProductVariation`	所有商品类型及商品变体共享的字段
`WooCommerceCrossSellableProduct`	支持定义"交叉销售"商品的商品
`WooCommerceDownloadableProductOrProductVariation`	支持可下载文件的商品（及商品变体）
`WooCommercePriceableProductOrProductVariation`	具有 `price` 字段的商品（及商品变体）
`WooCommerceShippableProductOrProductVariation`	支持配送设置的商品（及商品变体）
`WooCommerceTaxableProduct`	支持税务设置的商品
`WooCommerceWithStockManagementProductOrProductVariation`	支持库存管理的商品（及商品变体）

获取商品数据

以下 Query 获取所有商品类型的数据，并查询每种商品类型的所有字段：

Query 特定商品类型

可以通过在字段 woocommerceProducts 中筛选商品类型来查询特定商品类型：

query FilterProductsByType {
  woocommerceProducts(filter: { types: [simple, external, variable] }) {
    __typename
    ... on WooCommerceProduct {
      id
      name
      sku
    }
    ... on WooCommercePriceableProductOrProductVariation {
      price
    }
  }
  woocommerceProductsCount(filter: { types: [simple, external, variable] })
}

或者使用对应该类型的字段：

woocommerceSimpleProduct and woocommerceSimpleProducts
woocommerceExternalProduct and woocommerceExternalProducts
woocommerceGroupProduct and woocommerceGroupProducts
woocommerceVariableProduct and woocommerceVariableProducts

简单商品

此 Query 获取简单商品的数据：

query FetchSimpleProducts {
  woocommerceSimpleProducts {
    __typename
    id
    name
    sku
  }
  woocommerceSimpleProductsCount
}

外部商品

此 Query 获取外部商品的数据，包括外部 URL 和按钮文本：

query FetchExternalProducts {
  woocommerceExternalProducts {
    __typename
    id
    name
    sku
    externalURL
    buttonText
  }
  woocommerceExternalProductsCount
}

组合商品

此 Query 获取组合商品的数据，包括子商品：

query FetchGroupProducts {
  woocommerceGroupProducts {
    __typename
    id
    name
    sku
    children {
      id
      name
    }
    childrenCount
  }
  woocommerceGroupProductsCount  
}

可变商品

此 Query 获取可变商品的数据，包括变体：

query FetchVariableProducts {
  woocommerceVariableProducts {
    __typename
    id
    name
    sku
    variations {
      id
      name
      price
    }
    variationsCount
  }
  woocommerceVariableProductsCount
}

对于可变商品，也可以直接查询变体：

query GetProductVariations {
  woocommerceProductVariations {
    id
    name
    sku
    price
    parent {
      id
      name
      sku
    }
    priceFormatted
    regularPrice
    regularPriceFormatted
    salePrice
    salePriceFormatted
    stockStatus
    stockQuantity
    attributes {
      taxonomy
      termSlug
      termObject {
        id
        name
        slug
      }
    }
  }
}

使用筛选条件进行 Query

可以按各种条件对商品进行筛选、排序和分页：

query GetFilteredProducts {
  woocommerceProducts(pagination: { limit: -1 }, filter: { 
    types: [simple, external], 
    visibility: visible, 
    categoriesBy: { ids: [81] },
    tagsBy: { slugs: ["apple"] },
  }) {
    id
    name
    status
    type
    isVisible
    catalogVisibility
    categories(sort: { by: ID, order: DESC }) {
      id
      name
      slug
    }
    tags {
      id
      name
      slug
    }
  }
}
