etag¶

  # show the etag of an existing object (if fetched by listing
  # a bucket)
  print $object->etag . "\n";

delete¶

  # to delete an object
  $object->delete;

exists¶

  # to see if an object exists
  if ($object->exists) { ... }

get¶

  # to get the vaue of an object
  my $value = $object->get;

get_decoded¶

  # get the value of an object, and decode any Content-Encoding and/or
  # charset; see decoded_content in HTTP::Response
  my $value = $object->get_decoded;

get_filename¶

  # download the value of the object into a file
  my $object = $bucket->object( key => 'images/my_hat.jpg' );
  $object->get_filename('hat_backup.jpg');

last_modified, last_modified_raw¶

  # get the last_modified data as DateTime (slow)
  my $dt = $obj->last_modified;
  # or raw string in form '2015-05-15T10:12:40.000Z' (fast)
  # use this form if you are working with thousands of objects and
  # do not actually need an expensive DateTime for each of them
  my $raw = $obj->last_modified_raw;

key¶

  # show the key
  print $object->key . "\n";

put¶

  # to create a new object
  my $object = $bucket->object( key => 'this is the key' );
  $object->put('this is the value');

  # to create a new object which is publically-accessible with a
  # content-type of text/plain
  my $object = $bucket->object(
    key          => 'this is the public key',
    acl_short    => 'public-read',
    content_type => 'text/plain',
  );
  $object->put('this is the public value');

You may also set Content-Encoding using "content_encoding", and Content-Disposition using "content_disposition".

You may specify the S3 storage class by setting "storage_class" to either "standard", "reduced_redundancy", "standard_ia", or "onezone_ia"; the default is "standard".

put_filename¶

  # upload a file
  my $object = $bucket->object(
    key          => 'images/my_hat.jpg',
    content_type => 'image/jpeg',
  );
  $object->put_filename('hat.jpg');

  # upload a file if you already know its md5_hex and size
  my $object = $bucket->object(
    key          => 'images/my_hat.jpg',
    content_type => 'image/jpeg',
    etag         => $md5_hex,
    size         => $size,
  );
  $object->put_filename('hat.jpg');

You may also set Content-Encoding using "content_encoding", and Content-Disposition using "content_disposition".

You may specify the S3 storage class by setting "storage_class" to either "standard", "reduced_redundancy", "standard_ia", or "onezone_ia"; the default is "standard".

User metadata may be set by providing a non-empty hashref as "user_metadata".

query_string_authentication_uri¶

  # use query string authentication, forcing download with custom filename
  my $object = $bucket->object(
    key          => 'images/my_hat.jpg',
    expires      => '2009-03-01',
  );
  my $uri = $object->query_string_authentication_uri({
    'response-content-disposition' => 'attachment; filename=abc.doc',
  });

size¶

  # show the size of an existing object (if fetched by listing
  # a bucket)
  print $object->size . "\n";

uri¶

  # return the URI of a publically-accessible object
  my $uri = $object->uri;

initiate_multipart_upload¶

  #initiate a new multipart upload for this object
  my $object = $bucket->object(
    key         => 'massive_video.avi'
  );
  my $upload_id = $object->initiate_multipart_upload;

put_part¶

  #add a part to a multipart upload
  my $put_part_response = $object->put_part(
     upload_id      => $upload_id,
     part_number    => 1,
     value          => $chunk_content,
  );
  my $part_etag = $put_part_response->header('ETag')

  Returns an L<HTTP::Response> object. It is necessary to keep the ETags for
  each part, as these are required to complete the upload.

complete_multipart_upload¶

  #complete a multipart upload
  $object->complete_multipart_upload(
    upload_id       => $upload_id,
    etags           => [$etag_1, $etag_2],
    part_numbers    => [$part_number_1, $part_number2],
  );

  The etag and part_numbers parameters are ordered lists specifying the part
  numbers and ETags for each individual part of the multipart upload.

user_metadata¶

  my $object = $bucket->object(key => $key);
  my $content = $object->get; # or use $object->get_filename($filename)

  # return the user metadata downloaded, as a hashref
  my $user_metadata = $object->user_metadata;

To upload an object with user metadata, set "user_metadata" at construction time to a hashref, with no "x-amz-meta-" prefixes on the key names. When downloading an object, the "get", "get_decoded" and "get_filename" ethods set the contents of "user_metadata" to the same format.
