查找产品时出现Amazon Simple Product API错误

Question

from amazon.api import AmazonAPI

AMAZON_ACCESS_KEY = "A******************A"
AMAZON_SECRET_KEY = "7***********************E"
AMAZON_ASSOC_TAG = "j*****-20"

amazon = AmazonAPI(AMAZON_ACCESS_KEY, AMAZON_SECRET_KEY, AMAZON_ASSOC_TAG, region='US')
print(amazon)
#product = amazon.lookup(ItemId='B002RL8FBQ')

当我运行上面的代码时,它工作正常,我从打印功能获得此输出: <amazon.api.AmazonAPI object at 0x7fb6e59f7b38>

因此,我的访问密钥,密钥和关联标记一切正常.

但是,如果我取消注释最后一行,#product = amazon.lookup(ItemId='B00EOE0WKQ')那么我会收到此错误回溯:

Traceback (most recent call last):

    product = amazon.lookup(ItemId='B00EOE0WKQ')

我已经按照官方github的指示来访问https://github.com/yoavaviram/python-amazon-simple-product-api,我正在使用的代码将会看到我使用的"用法"子标题github页面,因此我不确定出了什么问题.

有关添加的信息,我正在使用虚拟环境,并显示我在这里安装了正确的软件包是我的pip冻结:

(myvenv) darren@my_comp:~/Python_projects/amazon_wp$ pip3 freeze
bottlenose==0.6.3
lxml==3.6.0
python-amazon-simple-product-api==2.1.0
python-dateutil==2.5.3
six==1.10.0

此外,我已经尝试了几个不同的asin数量的有效产品,我得到相同的错误消息.

我在ubuntu 14.04上使用python 3.4

我认为，问题出在地区。请从此处选择有效值。解释可能是 AWS 可以验证您的凭证，但当涉及“真实”调用时，它会失败，因为“美国”不是有效区域......
