Amazon web services 使用ASIN时Amazon api未显示价格

我需要从amazon jp获得最畅销的书籍及其详细信息

到目前为止，我可以买到最畅销的书，但它只为每一项提供

ASIN

和

TITLE

<TopSeller>
<ASIN>4047318752</ASIN>
<Title>艦これ白書 -艦隊これくしょん オフィシャルブック-</Title>
</TopSeller>

这是有效的，只是没有列出价格，我只是省略了另一个

响应组

如果你有另一个想法，获得最畅销的书的细节和价格。我非常高兴看到它

应赛博美赞臣的要求：

我想我找到了答案，尝试将您的回复组更改为

responseGroup（'Large，VariationSummary'）

然后通过

$response->Items->Item->VariationSummary->LowestPrice->Amount

---

添加VariationSummary使我能够获取缺少它们的少数项目的价格

您使用了错误的响应组。请看一下这篇文章，这是同一个问题，我给出了答案。您建议响应组“变体”在api响应中除了asin之外没有给我任何东西。但是你告诉了我aws api中的不一致性，我在那里补充了你的答案作为感谢。你能在这里发布请求和响应（XML）吗，在请求中设置“变体”RG。可能变体响应组根本不可用。我编辑了帖子以包含您的请求。从您的请求中，我看到您正在调用“&Operation=ItemSearch”操作，而不是“&Operation=ItemLookup”。您必须调用ItemLookup操作（正如您在初始示例中所做的那样）才能获取“变体”响应组。请修改您的请求并再次发布回复。
