我是Python和Boto的新手。我已经使用boto成功连接并检索了结果
mws = MWSConnection(accessKeyId,secretKey,Merchant=merchantId)
response = mws.list_matching_products(MarketplaceId=marketplaceId,Query="Shopkins")
我正在尝试通过UPC查找项目，这是我的代码：
mws = MWSConnection(accessKeyId,secretKey,Merchant=merchantId)
response = mws.get_matching_product_for_id(MarketplaceId=marketplaceId,IdType="UPC",IdList="013138304582")
我已经在Amazon MWS暂存器中测试了UPC，以验证它确实产生了结果。但是当我使用boto运行此命令时，我得到：
InvalidParameterValue
line 53, in <module>
response = mws.get_matching_product_for_id(MarketplaceId=marketplaceId,IdType="UPC",IdList="013138304582")

response.reason, body)
boto.mws.exception.InvalidParameterValue: InvalidParameterValue: Bad Request
One or more parameter values in the request is invalid.
Found duplicate value for IdList: 1
这是他们网站上有关功能的Boto文档：
MWSConnection.get_matching_product_for_id(*args, **kw)
MWS GetMatchingProductForId/2011-10-01 API call; quota=20 restore=20.00 Returns a list of products and their attributes, based on a list of Product IDs that you specify.
Lists: IdList.Id Required: MarketplaceId+IdType+IdList
我不知道为什么会这样，我觉得这是我的某种语法问题，但似乎无法弄清楚该怎么做。在Amazon MWS暂存器中，它将请求详细信息显示为：
&IdType=UPC
&IdList.Id.1=013138304582 HTTP/1.1
我尝试将IdList更改为IdList.Id和IdList.Id.1-但这只是给我Python中的语法错误。我相信这对有经验的人来说是简单的解决方法。任何帮助都将不胜感激。
最佳答案
IdList是类型list而不是str：
response = mws.get_matching_product_for_id(MarketplaceId=marketplaceId,IdType="UPC",IdList=["013138304582"])
