Amazon::S3::Thin::ResponseParser - A parser for S3 XML responses
use Amazon::S3::Thin; use Amazon::S3::Thin::ResponseParser; my $s3client = Amazon::S3::Thin->new({ aws_access_key_id => $aws_access_key_id, aws_secret_access_key => $aws_secret_access_key, region => $region, # e.g. 'ap-northeast-1' }); my $response_parser = Amazon::S3::Thin::ResponseParser->new(); my $res = $s3_client->list_objects($bucket); die $res->status_line if $res->is_error; my ($list_objects, $error) = $response_parser->list_objects($res->content); die $error->{message} if $error; # Print a list of the object keys in the bucket: print join "\n", map { $_->{key} } @{$list_objects->{contents}};
Amazon::S3::Thin::ResponseParser parses an XML response from S3 API.
This module provides a helper for the list_objects API which provide by Amazon::S3::Thin.
list_objects
This will create a new instance of Amazon::S3::Thin::ResponseParser.
If you specify the xml => $xml argument, you can replace the XML parser. The $xml should be an instance of XML::LibXML.
xml => $xml
$xml
my $res = $s3_client->get_object($bucket, $key); if ($res->is_error) { my $error = $response_parser->error($res->content); if ($error->{code} eq 'NoSuchKey') { die 'no such key'; } else { warn $error->{code}, $error->{message}; } }
This takes an XML response as $content and it will return an error. The $content should be valid XML formed Error Responses.
$content
$error is a hashref that looks like following form.
$error
{ code => 'NoSuchKey', message => 'The resource you requested does not exist', resource => '/mybucket/myfoto.jpg', request_id => '4442587FB7D0A2F9', };
This takes an XML response as $content and it will return a list of objects and an error if the $content has Error Responses. The $content should be valid XML formed GET Bucket (List Objects) Version 2 or GET Bucket (List Objects) Version 1.
$list_objects is a hashref that looks like following form. undef is returned if there is the $error.
$list_objects
{ common_prefixes => [], contents => [ { etag => 'fba9dede5f27731c9771645a39863328', key => 'my-image.jpg', last_modified => '2009-10-12T17:50:30.000Z', owner => { display_name => '', id => '' }, size => 434234, storage_class => 'STANDARD' }, ], delimiter => '', encoding_type => '', is_truncated => 0, max_keys => 1000, name => 'bucket', prefix => '', # v1 marker => '', next_marker => '', # v2 continuation_token => '', next_continuation_token => '', key_count => 205, start_after => '', };
$error is a hashref that looks like following form. undef is returned if there is the $list_objects.
