所以我在弄清楚为什么会出现特定错误时遇到了一些麻烦. [注意：我已经屏蔽了我的AccessKey和Signature参数]
以下网址返回ONE产品的有效xml.
http://ecs.amazonaws.com/onca/xml?AWSAccessKeyId=[myAccessKey]&IdType=ASIN&ItemId=B002UD52WQ&Operation=ItemLookup&ResponseGroup=Medium&Service=AWSECommerceService&Timestamp=2010-07-27T23:17:57.000Z&Signature=[mySignature]
但是,当我使用下面的url通过逗号分隔ASIN ID查找多个ASIN时,我收到错误
http://ecs.amazonaws.com/onca/xml?AWSAccessKeyId=[myAccessKey]&IdType=ASIN&ItemId=B002UD52WQ,B002C0CZEU&Operation=ItemLookup&ResponseGroup=Medium&Service=AWSECommerceService&Timestamp=2010-07-27T23:17:57.000Z&Signature=[mySignature]
错误信息：
The request signature we calculated
does not match the signature you
provided. Check your AWS Secret Access
Key and signing method. Consult the
service documentation for details
任何人都知道为什么会这样吗？提前致谢.
文档可以找到HERE“要一次查找多个项目,请用逗号分隔项目标识符.”
解决方法
傻,但你必须对逗号进行URL编码.希望这有助于那里的人.
