NAME

Amazon::SQS::Simple - OO API for accessing the Amazon Simple Queue Service

SYNOPSIS

    use Amazon::SQS::Simple;

    my $access_key = 'foo'; # Your AWS Access Key ID
    my $secret_key = 'bar'; # Your AWS Secret Key
    
    # Create an SQS object
    my $sqs = new Amazon::SQS::Simple($access_key, $secret_key);

    # Create a new queue
    my $q = $sqs->CreateQueue('queue_name');

    # Send a message
    $q->SendMessage('Hello world!');

    # Retrieve a message
    my $msg = $q->ReceiveMessage();
    print $msg->MessageBody() # Hello world!

    # Delete the message
    $q->DeleteMessage($msg->ReceiptHandle());

    # Delete the queue
    $q->Delete();

INTRODUCTION

Amazon::SQS::Simple is an OO API for the Amazon Simple Queue Service.

IMPORTANT

This version of Amazon::SQS::Simple defaults to work against version 2008-01-01 of the SQS API.

Earlier API versions may or may not work.

Actions dropped in recent versions will be dropped. Sometimes compatiblity among the Actions is not possible, e.g. Delete in 2007-05-01 takes a MessageId and in 2008-01-01 takes a ReceiptHandle. We change the request parameters based on the SQS API version, it is up to the caller to pass the correct value.

Bear in mind that earlier SQS versions are slated for deprecation - see aws.amazon.com for details.

CONSTRUCTOR

new($access_key, $secret_key)

Constructs a new Amazon::SQS::Simple object

$access_key is your Amazon Web Services access key. $secret_key is your Amazon Web Services secret key. If you don't have either of these credentials, visit http://aws.amazon.com/.

You may specify an optional named argument for the version of the SQS API you wish to use. This allows loading older data. E.g.:

 my $sqs = new Amazon::SQS::Simple($access_key, $secret_key, Version => '2007-05-01');

This is not guaranteed to work for all older versions. See IMPORTANT above.

METHODS

GetQueue($queue_endpoint)

Gets the queue with the given endpoint. Returns a Amazon::SQS::Simple::Queue object. (See Amazon::SQS::Simple::Queue for details.)

CreateQueue($queue_name, [%opts])

Creates a new queue with the given name. Returns a Amazon::SQS::Simple::Queue object. (See Amazon::SQS::Simple::Queue for details.)

Options for CreateQueue:

DefaultVisibilityTimeout => SECONDS

Set the default visibility timeout for this queue

ListQueues([%opts])

Gets a list of all your current queues. Returns an array of Amazon::SQS::Simple::Queue objects. (See Amazon::SQS::Simple::Queue for details.)

Options for ListQueues:

QueueNamePrefix => STRING

Only those queues whose name begins with the specified string are returned.

FUNCTIONS

No functions are exported by default; if you want to use them, export them in your use line:

    use Amazon::SQS::Simple qw( timestamp );
timestamp($seconds)

Takes a time in seconds since the epoch and returns a formatted timestamp suitable for using in a Timestamp or Expires optional method parameter.

STANDARD OPTIONS

The following options can be supplied with any of the listed methods.

AWSAccessKeyId => STRING

The AWS Access Key Id to use with the method call. If not provided, Amazon::SQS::Simple uses the value passed to the constructor.

SecretKey => STRING

The Secret Key to use with the method call. If not provided, Amazon::SQS::Simple uses the value passed to the constructor.

Timestamp => TIMESTAMP

All methods are automatically given a timestamp of the time at which they are called, but you can override this value if you need to. The value for this key should be a timestamp as returned by the Amazon::SQS::Simple::timestamp() function.

You generally do not need to supply this option.

Expires => TIMESTAMP

All methods are automatically given a timestamp of the time at which they are called. You can alternatively set an expiry time by providing an Expires option. The value for this key should be a timestamp as returned by the Amazon::SQS::Simple::timestamp() function.

You generally do not need to supply this option.

ACKNOWLEDGEMENTS

Bill Alford wrote the code to support basic functionality of older API versions in release 0.9.
