java - 尝试使用 Amazon Product Affiliate API 时出错

Question

我正在尝试使用亚马逊产品附属 API，这真是一次令人困惑的体验。

我已注册 AWS，因此拥有我的 ACCESS_KEY_ID 和 SECRET_ACCESS_KEY 此外，我还已注册 https://affiliate-program.amazon.com/ 并获得了我的跟踪 ID

现在尝试使用此 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

我收到错误

<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>

我已提供所需的所有参数，但不确定为什么信息不匹配。如果我从 URL 中删除 AssociateTag 参数，则会收到以下错误:

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

AssociateTag 与我注册 amazon link 后收到的跟踪 ID 是否不同？

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

这对我有用。您的签名可能有问题。 AssociateTag 是您注册成员(member)后获得的“关联 ID”，而不是任何跟踪 ID。我与 Amazon.co.uk Associates 签约。
