Does not handle keys with multiple consecutive "/" characters

[kpeters-cbsi]

Using version 0.87.

I'm trying to retrieve a key similar to "foo//bar/baz/bak/20210208160007". Using the AWS S3 CLI, the following works:

aws s3api head-object --bucket my-bucket --key "foo//bar/baz/bak/20210208160007"

But using Net::Amazon::S3, the following code snippet dies:

use strict;
use warnings;

use Net::Amazon::S3;
use Data::Dumper;

my $bucket = 'my-bucket';
my $key = 'foo//bar/baz/bak/20210208160007';

my $s3 = Net::Amazon::S3->new( {use_iam_role => 1, retry => 1} );
my $b = $s3->bucket($bucket);
my $res = $b->get_key($key) or do {
    my $err = '';
    if ($s3->err) {
        $err .= $s3->err . ': ';
    }
    if ($s3->errstr) {
        $err .= $s3->errstr;
    }
    die $err if $err;
    die "s3 did not indicate the cause of the error";
};

Looking at this a bit, I noted that Net::Amazon::S3::Request::_build_signed_request will replace multiple consecutive / chars with a single /. While I think this is related, simply commenting out that line didn't cut it.

along with mentioned L160 in _build_signed_request you have to comment _simplify_uri call (L172) in V4Implementation.pm;

According https://docs.aws.amazon.com/general/latest/gr/sigv4-create-canonical-request.html
multi slash sequence is not allowed in CanonicalUri, so I'll try to treat key as single string (Request::Object L17)

	return super . $self->s3->_urlencode($self->key);

Hm, I read documentation once again and now I noticed a note "do not normalize uri for S3" ... will be fixed in v0.991
