400 Bad Request respond from non default region

[tal5ab]

Hi
I am trying to download a file from few S3 buckets
Files from Location: US West (Oregon) (us-west-2) works fine (This is Amazone default region)
But when i try to get from Location: EU (Frankfurt) (eu-central-1) i get Amazon::S3: Amazon responded with 400 Bad Request

How do i tell this module my bucket is located in non default region?
There is no mention of this in the docs as far as i can see

my code

	my $s3 = Amazon::S3->new({
			aws_access_key_id     => $accessKey,
			aws_secret_access_key => $secret_access_key,
			retry                 => 1,
	});
		my $bucket = $s3->bucket($bucket_name);
		my $response = $bucket->get_key_filename($path_to_file,'GET',$destination_file) or die $s3->err . ": ". $s3->errstr;

When you create a new S3 client object, use argument host:

* host *
   The S3 host endpoint to use. Defaults to 's3.amazonaws.com'. 
   This allows you to connect to any S3-compatible host.

Net::Amazon::S3->new( { host => 's3.ca-central-1.amazonaws.com' , aws_access_key_id...} )

Thank you for such a fast respond
But i tried all 3 possible EU URLs:
s3.eu-central-1.amazonaws.com
s3-eu-central-1.amazonaws.com
s3.dualstack.eu-central-1.amazonaws.com

	my $s3 = Amazon::S3->new({
			host				  => 's3.dualstack.eu-central-1.amazonaws.com',
			aws_access_key_id     => $accessKey,
			aws_secret_access_key => $secret_access_key,
			retry                 => 1,
	});

None of them worked
Still getting 400

You are using Amazon::S3, not Net::Amazon::S3

I strongly recommend you to adapt your code to use Net::Amazon::S3 on version 0.80 (before this version, I can't recommend either!)

	my $s3 = Net::Amazon::S3->new({
			host				  => 's3-eu-central-1.amazonaws.com',
			aws_access_key_id     => $accessKey,
			aws_secret_access_key => $secret_access_key,
			retry                 => 1,
	});

's3-eu-central-1.amazonaws.com' seems wrong; have you tried 's3.eu-central-1.amazonaws.com' ?

The problem is the Frankfurt region uses AWS signatures version 4, I don't believe this module implements them, yet.
