NAME

Yars::Client - Yet Another RESTful-Archive Service Client

VERSION

version 0.94

SYNOPSIS

my $r = Yars::Client->new;

# Send and retrieve content.
my $location = $y->send(content => 'hello, world') or die $y->errorstring;
say $y->retrieve(location => $location);

# Alternatively, use names and md5s explicitly.
my $location = $y->send(content => 'hello there', name => "greeting");
my $md5 = $y->res_md5;
say $y->retrieve(filename => 'greeting', md5 => $md5);

# Upload a file.
$r->upload($filename) or die $r->errorstring;
print $r->res->headers->location;

# Download a file.
$r->download($filename, $md5) or die $r->errorstring;
$r->download($filename, $md5, '/tmp');   # download it to the /tmp directory
$r->download("http://yars/0123456890abc/filename.txt"); # Write filename.txt to current directory.

# More concise version of retrieve.
my $content = $r->get($filename,$md5);

# Delete a file.
$r->remove($filename, $md5) or die $r->errorstring;

# Compute the URL of a file based on the md5 and the buckets.
print $r->location($filename, $md5);

print "Server version is ".$r->status->{server_version};
my $usage = $r->disk_usage();      # Returns usage for a single server.
my $nother_usage = Yars::Client->new(url => "http://host1:9999")->disk_usage();
my $status = $r->servers_status(); # return a hash of servers, disks, and their statuses

# Mark a disk down.
my $ok = $r->set_status({ root => "/acps/disk/one", state => "down" });
my $ok = $r->set_status({ root => "/acps/disk/one", state => "down", host => "http://host2" });

# Mark a disk up.
my $ok = $r->set_status({ root => "/acps/disk/one", state => "up" });

# Check a manifest file or list of files.
my $details = $r->check_manifest( $filename );
my $check = $r->check_manifest( "-c", $filename );
my $check = $r->check_manifest( "--show_corrupt" => 1, $filename );
my $ck = $r->check_files({ files => [
    { filename => $f1, md5 => $m1 },
    { filename => $f2, md5 => $m2 } ] });
