我正在尝试使用亚马逊产品附属API，这是一个非常令人困惑的体验

我已经注册了AWS，所以我有我的
ACCESS\u KEY\u ID
和
SECRET\u ACCESS\u KEY
此外，我还注册了
https://affiliate-program.amazon.com/
并已获得我的
跟踪ID

现在，当尝试使用此URL发出请求时

http://ecs.amazonaws.com/onca/xml?
AWSAccessKeyId=AKIAI4E9BPWYGSC7VNZQ
&ItemId=0545010225
&Operation=ItemLookup
&ResponseGroup=Small
&Service=AWSECommerceService
&Timestamp=2014-03-05T15%3A55%3A46Z
&Version=2009-03-31
&Signature=mb6Stjz4I5GHV51bxVyACS4T%2FwGjplkVymW8eLDoh4Q%3D
&AssociateTag=sample026-20
我犯了一个错误

<Error>
    <Code>SignatureDoesNotMatch</Code>
    <Message>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.</Message>
</Error>
我已经提供了所需的所有参数，但不确定为什么信息不匹配。 如果我从URL中删除
AssociateTag
参数，则会出现以下错误：

<Error>
   <Code>AWS.MissingParameters</Code>
   <Message>Your request is missing required parameters. Required parameters include AssociateTag.</Message>
</Error>

AssociateTag
是否与我注册后收到的
跟踪ID
有所不同

我正在尝试获取示例代码表单
http://aws.amazon.com/code/Product-Advertising-API/2478
执行。除非有更好的选择……

它适合我。你的签名可能有问题。AssociateTag是您注册会员后获得的“会员ID”，而不是任何跟踪ID。我为Amazon.co.uk Associates注册
