I've been debugging ASIN gem for Amazon product API which uses HTTPI.get(url) It was working fine until most recently, the HTTPI.get(url) request returns the following error:
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>'
My httpi gem is v2.2.4 I also tried using HTTParty.get(url) which works fine
What could've caused this?
This turned out to be a HTTPI versioning problem.
HTTPI 2.0.0 works properly, but latest version 2.2.4 has this issue
