我有一个例子，当productsearch亚马逊目录中的返回预期的产品，但listCatalogItems它没有。我不确定第一个是否可以在 API 中访问，但我认为应该有一个类似的替代方案。

https://sellercentral-europe.amazon.com/product-search/search?q=461439-001

这将调用https://sellercentral-europe.amazon.com/productsearch/search?query=461439-001&page=1URL：

{
    "numberOfPages": 1,
    "numberOfResults": 3,
    "indexSummaries": [...],
    "products": [{
        "asin": "B07HGQV1MS",
        "detailPageURL": "http://www.amazon.co.uk/dp/B07HGQV1MS",
        "imageUrl": "https://m.media-amazon.com/images/I/51NbiwOo98L._SS160_.jpg",
        "title": "HP Z600 Dual LGA1366 System Board 461439-001 460840-002 (Certified Refurbished)",
        ...
    }, ...],
    "debugInfo": []
}

现在，当使用 Node.js 使用 SP API 搜索相同的东西时，我们会得到完全不同的东西：

const getASINFromPartNumber = async partNumber => {
  const res = await sellingPartner.callAPI({
    operation: "listCatalogItems",
    endpoint: "catalogItems",
    query: {
      MarketplaceId: ['A1F83G8C2ARO7P'],
      Query: partNumber
    }
  })
  const asin = findValue(res, "Items.0.Identifiers.MarketplaceASIN.ASIN")
  return asin
}

const asin = await getASINFromPartNumber("461439-001")

这是回应：

> console.log(res.Items[0])
< { Identifiers:
<    { MarketplaceASIN: { MarketplaceId: 'A1F83G8C2ARO7P', ASIN: 'B079184W1J' } },
<   AttributeSets:

<        PartNumber: '651687-001',

<   Relationships: [],
<   SalesRankings:
<    [ { ProductCategoryId: 'pc_display_on_website', Rank: 34592 },
<      { ProductCategoryId: '430435031', Rank: 213 } ] }

为什么我们在相同的输入下得到完全不同的结果？换句话说，通过将部件号作为输入来获取 ASIN 的最佳方法是什么？
