VERSION
version 0.99
SYNOPSIS
use Net::Amazon::S3;

ok($bucket->add_key("key", "data"));
ok($bucket->add_key("key", "data", {
content_type => "text/html",

ok($bucket->add_key("key", "data", {
encryption => 'AES256',

# the err and errstr methods just proxy up to the Net::Amazon::S3's
# objects err/errstr methods.

DESCRIPTION
This module represents an S3 bucket. You get a bucket object from the Net::Amazon::S3
object.
METHODS
new
Create a new bucket object. Expects a hash containing these two arguments:
bucket
account
add_key
Takes three positional parameters:
key
value
configuration
A hash of configuration data for this key.
acl
encryption
any additional HTTP header
See Net::Amazon::S3::Operation::Object::Add::Request for details
Returns a boolean.
add_key_filename
Use this to upload a large file to S3. Takes three positional parameters:
key
filename
configuration
A hash of configuration data for this key. (See synopsis);
Returns a boolean.
copy_key
Creates (or replaces) a key, copying its contents from another key elsewhere in S3. Takes
the following parameters:
key The key to (over)write
source
Where to copy the key from. Should be in the form "/bucketname/keyname"/.
conf
Optional configuration hash. If present and defined, the configuration (ACL and
headers) there will be used for the new key; otherwise it will be copied from the
source key.
edit_metadata
Changes the metadata associated with an existing key. Arguments:
key The key to edit
conf
The new configuration hash to use
head_key KEY
Takes the name of a key in this bucket and returns its configuration hash
query_string_authentication_uri KEY, EXPIRES_AT
my $uri = $bucket->query_string_authentication_uri (
key => 'foo',
expires_at => time + 3_600, # valid for one hour
);
my $uri = $bucket->query_string_authentication_uri (
key => 'foo',
expires_at => time + 3_600,
method => 'PUT',
);
Returns uri presigned with your credentials.
When used with Signature V4 you have to specify also HTTP method this presigned uri will
be used for (default: "GET")
Method provides authenticated uri only for direct object operations.
Method follows API's "CALLING CONVENTION".
Recognized positional arguments (mandatory).
key
expires_at
Expiration time (epoch time).
Optional arguments
method
Default: "GET"
Intended HTTP method this uri will be presigned for.
Signature V2 doesn't use it but Signature V4 does.
See <https://docs.aws.amazon.com/AmazonS3/latest/dev/PresignedUrlUploadObject.html>
get_key $key_name [$method]
Takes a key name and an optional HTTP method (which defaults to "GET". Fetches the key
from AWS.
On failure:
Returns undef on missing content, throws an exception (dies) on server errors.
On success:
Returns a hashref of { content_type, etag, value, @meta } on success. Other values from
the server are there too, with the key being lowercased.
get_key_filename $key_name $method $filename
Use this to download large files from S3. Takes a key name and an optional HTTP method
(which defaults to "GET". Fetches the key from AWS and writes it to the filename. THe
value returned will be empty.
On failure:
Returns undef on missing content, throws an exception (dies) on server errors.
On success:
Returns a hashref of { content_type, etag, value, @meta } on success
delete_key $key_name
Removes $key from the bucket. Forever. It's gone after this.
Returns true on success and false on failure
delete_bucket
Delete the current bucket object from the server. Takes no arguments.
Fails if the bucket has anything in it.
This is an alias for "$s3->delete_bucket($bucket)"
list
List all keys in this bucket.
see "list_bucket" in Net::Amazon::S3 for documentation of this method.
list_all
List all keys in this bucket without having to worry about 'marker'. This may make
multiple requests to S3 under the hood.
see "list_bucket_all" in Net::Amazon::S3 for documentation of this method.
get_acl
Takes one optional positional parameter
key (optional)
If no key is specified, it returns the acl for the bucket.
Returns an acl in XML format.
set_acl
Takes a configuration hash_ref containing:
acl_xml (cannot be used in conjunction with acl_short)
An XML string which contains access control information which matches Amazon's
published schema. There is an example of one of these XML strings in the tests for
this module.
acl_short (cannot be used in conjunction with acl_xml)
You can use the shorthand notation instead of specifying XML for certain 'canned'
types of acls.
(from the Amazon API documentation)
private: Owner gets FULL_CONTROL. No one else has any access rights. This is the
default.
public-read:Owner gets FULL_CONTROL and the anonymous principal is granted READ
access. If this policy is used on an object, it can be read from a browser with no
authentication.
public-read-write:Owner gets FULL_CONTROL, the anonymous principal is granted READ and
WRITE access. This is a useful policy to apply to a bucket, if you intend for any
anonymous user to PUT objects into the bucket.
authenticated-read:Owner gets FULL_CONTROL, and any principal authenticated as a
registered Amazon S3 user is granted READ access.
key (optional)
If the key is not set, it will apply the acl to the bucket.
Returns a boolean.
get_location_constraint
Retrieves the location constraint set when the bucket was created. Returns a string (eg,
'EU'), or undef if no location constraint was set.
err
The S3 error code for the last error the object ran into
errstr
A human readable error string for the last error the object ran into
add_tags
# Add tags for a bucket
$s3->add_tags ({
bucket => 'bucket-name',
tags => { tag1 => 'value-1', tag2 => 'value-2' },
});
# Add tags for an object
$s3->add_tags ({
bucket => 'bucket-name',
key => 'key',
tags => { tag1 => 'value-1', tag2 => 'value-2' },
});
Takes configuration parameters
key (optional, scalar)
If key is specified, add tag(s) to object, otherwise on bucket.
tags (mandatory, hashref)
Set specified tags and their respective values.
version_id (optional)
Is specified (in conjunction with "key") add tag(s) to versioned object.
Returns "true" on success.
Returns "false" and sets "err"/"errstr" otherwise.
delete_tags
# Add tags for a bucket
$s3->delete_tags ({
bucket => 'bucket-name',
});
# Add tags for an object
$s3->delete_tags ({
bucket => 'bucket-name',
key => 'key',
version_id => $version_id,
});
Takes configuration parameters
key (optional, scalar)
If key is specified, add tag(s) to object, otherwise on bucket.
version_id (optional)
Is specified (in conjunction with "key") add tag(s) to versioned object.
Returns "true" on success.
Returns "false" and sets "err"/"errstr" otherwise.
