【问题】
AWS中,想要查询某个产品,一共还剩多少个可以买。
【解决过程】
1.知道是用ItemLookup。
2.参考:
【记录】申请AWS的AWSAccessKeyId(AWS Access Key ID)
找到了API的页面:
http://docs.aws.amazon.com/AWSECommerceService/latest/DG/ProgrammingGuide.html
3.找到了:
AWS Documentation » Amazon Product Advertising API Docs » Developer Guide » Programming Guide » Returning Price and Availability Information » Returning Prices » Offer Summaries Offer SummariesThe OfferSummary response group returns summary information about offers, including:
For example, the following response snippet shows the lowest prices for an item in New and Used condition. <OfferSummary> <LowestNewPrice> <Amount>801</Amount> <CurrencyCode>USD</CurrencyCode> <FormattedPrice>$8.01</FormattedPrice> </LowestNewPrice> <LowestUsedPrice> <Amount>799</Amount> <CurrencyCode>USD</CurrencyCode> <FormattedPrice>$7.99</FormattedPrice> </LowestUsedPrice> <TotalNew>45</TotalNew> <TotalUsed>20</TotalUsed> <TotalCollectible>0</TotalCollectible> <TotalRefurbished>0</TotalRefurbished> </OfferSummary> |
【总结】
用其中的TotalNew和TotalUsed,相加,即可得出还有多少个。
