Amazon E-Commerce Service の SubscriptionId が AWSAccessKeyId に変更

  http://hail2u.net/blog/coding/from-subscriptionid-to-awsaccesskeyid.html

  Amazon Web Services にログインして,右上の
 Your Web Services Account
  にマウスを合わせて,View Access Key Identifiers を選択すると,Access Key ID が表示される.

  Subscription ID もあったので見てみてると,

Since you created your AWS account before October 10, 2005,
you have an AWS Subscription ID. If you have already built an
AWS application using your Subscription ID, you may continue
using your Subscription ID. If you are building a new AWS
application, we encourage you to use your Secret Access Key
and Access Key ID instead.

  とのことで,今後は,Access Key ID (AWSAccessKeyId) が推奨されるそうです.

  試しに,手元のアプリケーションの SubscriptionId を,リクエストも含めて AWSAccessKeyId に変更してみたら,問題なくいけました.
