如何修复 HTTP 错误 503：服务不可用错误

Question

执行命令：

amazon = bottlenose.Amazon(AMAZON_ACCESS_KEY,AMAZON_SECRET_KEY,AMAZON_ASSOC_TAG)
response = amazon.ItemLookup(ItemId='B007OZNUCE')

我得到了错误：

    response = amazon.ItemLookup(ItemId='B007OZNUCE')

缺少地区，根据您使用的国家/地区添加“DE”或“ES”之类的内容。

默认为“美国”：

amazon = bottlenose.Amazon(AWS_ACCESS_KEY_ID, AWS_SECRET_ACCESS_KEY, AWS_ASSOCIATE_TAG, Region='FR')

另外：您是否已在“亚马逊”客户门户中检查了您要使用的国家/地区的“平台 API”访问权限是否启用了 API？

• 法国：https://partenaires.amazon.fr/assoc_credentials/home

• 英国：https://affiliate-program.amazon.co.uk/assoc_credentials/home

• 美国：https://affiliate-program.amazon.com/assoc_credentials/home

对我来说，它显示为非活动状态，因此，这可能是请求被拒绝的原因。

感谢您的意见！

同样的代码现在神奇地工作了。似乎 api 密钥在创建后没有立即启用。
