最近，我开始学习 Python。我计划为我们公司构建一个程序来管理来自所有亚马逊市场网站、我们自己的 Bigcommerce 商店和 eBay 的订单。
现在我可以使用 Boto 库成功向 Amazon US、Amazon Canada 和 Amazon Mexico 发送请求并获取所有订单信息。（Boto 是我能找到的唯一一个与亚马逊 MWS 完美配合的库）但是当我使用相同的方法向 Amazon.co.uk 发送请求时，它失败了。这是我用来发送请求的示例代码。
from boto.mws.connection import MWSConnection
MarketPlaceID = marketplaceid
MerchantID = merchantid
AccessKeyID = accesskeyid
SecretKey = secretkey
mws = MWSConnection(AccessKeyID,SecretKey)
mws.SellerId = MerchantID
mws.Merchant = MerchantID
mws.MarketplaceId = MarketPlaceID
orderstatus = ['PartiallyShipped','Unshipped', 'Shipped']
orders=mws.list_orders(LastUpdatedAfter = '2016-05-01T17:00:00Z', MarketplaceId = [MarketPlaceID],OrderStatus=orderstatus)
此代码非常适用于我们在亚马逊加拿大、亚马逊美国和亚马逊墨西哥的商店。但是当我将它用于 Amazon.co.uk. 时，我总是得到这些 AccessDenied 代码。（我 100% 确认所有的 marketplaceid、sellersid、accesskeyid 和 secretkeyid 都是正确的。）
AccessDenied

谁能告诉我如何通过 Python Boto 库或其他 Python 库提出连接到 Amazon.co.uk 的请求？任何帮助将不胜感激。
谢谢
