======================Then========================
github.com/smartystreets/go-aws-auth HAVE bug for regoin, auto regoin can't v4
some just change source code
go\src\github.com\smartystreets\go-aws-auth\awsauth.go
func Sign
signVersion := awsSignVersion[service]
signVersion=4 //add this line in here. let api just use v4
Now ok to use this code.
