Php - 使用Amazon API获取amazon产品的当前价格

Question

我已使用以下代码中的代码成功实施了亚马逊产品搜索：

I don't get prices with Amazon Product Advertising API

现在我正在尝试从亚马逊获取产品的当前价格。我只得到零售价。

例如，当我尝试使用amazon API获取产品价格http://www.amazon.com/gp/product/0743273567/ref=ox_sc_act_title_1?ie=UTF8&psc=1&smid=ATVPDKIKX0DER时，我得到以下值：

ListPrice] => Array
                    (
                        [0] => Array
                            (
                                [Amount] => 1500
                                [CurrencyCode] => USD
                                [FormattedPrice] => $15.00
                            )

                    )
....

[OfferSummary] => Array

                    (
                        [0] => Array
                            (

                            )

                    )

                                [FormattedPrice] => $2.50
                            )

                                                                [FormattedPrice] => $11.57
                                                            )

                                                    )

                                                [PercentageSaved] => 77 .....

零售价： $ 15.00 可以在ListPrice参数中看到，但我无法在api响应中找到当前价格： $ 7.70 。

我还尝试了各种ResponseGroup，例如：Offers，OfferFull，Large，Medium等。

请帮帮我。 在此先感谢！

这可能有点迟，但要获得当前价格，您需要包含商品响应组，然后从此节点获取当前价格

$price = htmlentities((string) $item->Offers->Offer->OfferListing->Price->Amount);

因为XML实际上看起来像这样

<Item> 
  <ASIN>B00KOKTZLQ</ASIN> 
  <OfferSummary> 
    <LowestNewPrice> 
      <Amount>3998</Amount> 
      <CurrencyCode>USD</CurrencyCode> 
      <FormattedPrice>$39.98</FormattedPrice> 
    </LowestNewPrice>  
    <TotalNew>4</TotalNew> 
    <TotalUsed>0</TotalUsed> 
    <TotalCollectible>0</TotalCollectible> 
    <TotalRefurbished>0</TotalRefurbished> 
  </OfferSummary> 
  <Offers> 
    <TotalOffers>1</TotalOffers> 
    <TotalOfferPages>1</TotalOfferPages>

从amazon docs开始，它表示Operation=ItemLookup会返回产品数据，并且您会从该回复中获得<LowestNewPrice><Amount>代码，该代码会为您提供所请求商品的最新价格。所以请参考亚马逊提供的文件。

希望这会对你有所帮助。

谢谢！

您可以轻松获得响应组的价格，例如： responseGroup（ '中，OfferSummary，VariationSummary'）

关键：VariationSummary有一个你可以找到的对象：

• LowestPrice
• HighestPrice
• LowestSalePrice
• HighestSalePrice

请注意，您可能无法在variationSummery对象中获得以上所有价格参数，因此请进行相应的检查。
