我一直在为Amazon产品API调试ASIN gem，该API使用HTTPI.get（url）它工作正常，直到最近，HTTPI.get（url）请求返回以下错误：

HTTPI GET request to webservices.amazon.com (excon)
got response='<?xml version="1.0"?>
<ItemSearchErrorResponse xmlns="http://ecs.amazonaws.com/doc/2011-08-01/"><Error>
<Code>SignatureDoesNotMatch</Code>
<Message>The request signature we calculated does not match the signature you provided. Check your AWS Secret Access Key and signing method. Consult the service documentation for details.</Message></Error>
<RequestId>b73cc1c9-a682-453f-a8c8-1fcc5d1f3767</RequestId></ItemSearchErrorResponse>'

我的httpi gem是v2.2.4 我还尝试了使用HTTParty.get（url），效果很好

是什么导致了这种情况？

这是一个HTTPI版本控制问题

httpi2.0.0工作正常，但最新版本2.2.4存在此问题
