具有13位ISBN的Amazon AWS ItemLookup

Question

我曾经能够做13位数的ISBN查找,但现在我做不到.

这是对13位ISBN的查询:9780073380957.

http://ecs.amazonaws.com/onca/xml?AWSAccessKeyId=&ItemId = 9780073380957&Operation = ItemLookup&ResponseGroup = Images%2CItemAttributes&Service = AWSECommerceService&Timestamp = 2009-12-16T14%3A30%3A02Z&Version = 2009-06-01&Signature =

返回:f6770ab1-9b3e-48d3-9492-750e8d773c1b0.0053760000000000TrueNewShipASINAmazon19780073380957ImagesItemAttributes1-SubmissionDateAllAWS.InvalidParameterValue9780073380957不是ItemId的有效值.请更改此值,然后重试您的请求.

但是,同一本书的10位数ISBN有效:

http://ecs.amazonaws.com/onca/xml?AWSAccessKeyId=&ItemId = 0073380954&Operation = ItemLookup&ResponseGroup = Images%2CItemAttributes&Service = AWSECommerceService&Timestamp = 2009-12-16T14%3A44%3A10Z&Version = 2009-06-01&Signature =

我正在使用pyaws,如果这有任何区别.

Answer 1

事实证明,我需要将IdType指定为"ISBN",将SearchIndex指定为"Books".

这是现在的工作查询:

http://ecs.amazonaws.com/onca/xml?AWSAccessKeyId=[my_key]&IdType=ISBN&ItemId=9780073380957&Operation=ItemLookup&ResponseGroup=Images%2CItemAttributes&SearchIndex=Books&Service=AWSECommerceService&Timestamp=2009-12-16T14%3A51%3A21Z&Version=2009-06-01&Signature = [签名]
