Listing all objects on ECS via Atmos API returns 1002One or more arguments in the request were invalid.

Hi All,

I am struggling to get /rest/objects working on ECS via Atmos API.

When I run the following code on Atmos via Atmos API it works fine, it lists all the objects; however, when I run the same query against ECS I get the following error:

http://www.emc.com/cos/">1002One or more arguments in the request were invalid.

The script I am using is modified version of the one here:

Error 1032 while executing REST API Calls

I can get all the other commands working fine like /rest/objects?listabletags etc... it is only /rest/objects that does not work.

Also I have tried a similar shell script and results are the same

Perl Code:

#!/usr/bin/perl
use strict;
use Time::Local;
use MIME::Base64;
use Digest::SHA qw(hmac_sha1);

sub _MyUTCTime(){
my @Time=split(" ",scalar gmtime());
my ($Wkday,$Mon,$Day,$time,$year) = @Time;
my $UTCTime = $Wkday . ", " . $Day . " $Mon" . " $year " . $time . " GMT";
return $UTCTime;
}

my $UserID='/';
my $SharedSecret = 'xxxx';
my $Subtenantid='xxxxxxx';
my $HostName='https://xxxxxx:443';


my $url_atmos_path='/rest/objects';


my $combinestring = $HostName . $url_atmos_path;


print "$combinestring\n";





my $HTTPRequestMethod = 'GET';
my $ContentType = "application/octet-stream";
my $Range = "";
my $Date= _MyUTCTime;
my $CanonicalizedResource = '/rest/objects';




my $CanonicalizedEMCHeaders = 'x-emc-date:'.$Date."\n".'x-emc-subtenant-id:'.$Subtenantid."\n".'x-emc-uid:'.$UserID;

my $HashString = $HTTPRequestMethod . "\n" . $ContentType . "\n" . $Range . "\n". "\n".$CanonicalizedResource . "\n" . $CanonicalizedEMCHeaders;

print "StringToSign:\n$HashString\n";

my $DecodedSharedSecret = decode_base64($SharedSecret);

my $digest=hmac_sha1($HashString,$DecodedSharedSecret);

my $EMCSignature= encode_base64($digest, "");




my $cmd =  `curl -k -s -v -H "Content-Type:$ContentType" -H "x-emc-date:$Date" -H "x-emc-subtenant-id:$Subtenantid" -H "x-emc-uid:$UserID" -H "x-emc-signature:$EMCSignature" -X GET $combinestring`;

print "$cmd\n";


print "$CanonicalizedEMCHeaders\n";


print "$HashString\n";

Just to clarify, on ECS I am using 9023 port so that will be the "only" difference. Also, I have tried with and without subtenant-id in the header and same 1002 error occurs in both cases.

In addition, I just tested /rest/namespace query on its own and on Atmos it works fine but on ECS it returns:

http://www.emc.com/cos/">1001The server encountered an internal error. Please try again.

Same caveats apply i.e. tried with x-emc-subtenant-id header and without... no change.
