so i constructed this in perl like this, seems working well

#!/usr/bin/perl -w
use HTTP::Tiny;
use POSIX qw(strftime);

my $ua = HTTP::Tiny->new;

$timestamp = strftime '%Y-%m-%dT%H:%M:%S', gmtime();
$ip = $ENV{'REMOTE_ADDR'};
$Nonce = int(rand(1000000));
$from = "sfsdfdf";
$message = "asdasd";
$to = "434534543";

my $url = "https://sms-intl.ap-southeast-1.aliyuncs.com";

my $data = {
    AccessKeyId  => "sdsadasdasd",
    Action    => "SendMessageToGlobe",
    Format      => "JSON",
    From => $from,
    Message => $message,
    RegionId => "default",
    SecureTransport => "true",
    SignatureMethod => "HMAC-SHA1",
    SignatureNonce => $Nonce,
    SignatureVersion => "1.0",
    SourceIp => $ip,
    Timestamp => $timestamp,
    To => $to,
    Version => "2018-05-01",
    Signature => "j7UIvC+9whf1KyLxTjv0K4aFCyc=",
};

my $params = $ua->www_form_urlencode( $data );

my $response = $ua->post( $url . '/?' . $params );

print "Content-type: text/html\n\n";
print $response->{content} . "\n";

sometimes i get Signature was already used

so my question is, does signature have to be random generated. coz thats the only error am facing only

coz when i run there direct code in through there system, it works well and wen i check debug report. in cloud account. i see signature changed
