NAME

Amazon::SQS::Client - client interface to Amazon Simple Queue Service

SYNOPSIS

# create an HTTP client
my $client = Amazon::SQS::Client->new( $AWS_ACCESS_KEY_ID, $AWS_SECRET_ACCESS_KEY );

# send a message
my $response = $client->sendMessage(
  { QueueUrl    => $AWS_QUEUE_URL,
    MessageBody => $message
  }
);

DESCRIPTION

Amazon::SQS::Client is the implementation of a service API to Amazon's Simple Queue Service.

NOTE: The classes that implement the SQS Perl framework were originally provided by AWS back in the day when Perl was an important part of the AWS development stack. Fast forward to 2024 and Perl is no longer a supported language in the AWS SDK ecosystem. These modules "work" and provide a fairly simple toolset for working with SQS. There are more popular and perhaps more supported packages available for interacting with SQS. See "SEE ALSO" for recommended alternatives. You may however find this implementation lighter in weight than other implementations.

DETAILS

Amazon Simple Queue Service (Amazon SQS) offers a reliable, highly scalable hosted queue for storing messages as they travel between computers.

By using Amazon SQS, developers can simply move data between distributed application components performing different tasks, without losing messages or requiring each component to be always available. Amazon SQS works by exposing Amazon's web-scale messaging infrastructure as a web service. Any computer on the Internet can add or read messages without any installed software or special firewall configurations. Components of applications using Amazon SQS can run independently, and do not need to be on the same network, developed with the same technologies, or running at the same time.

METHODS AND SUBROUTINES

new

new( aws-access-key-id, aws-secret-access-key, [token], [options] )

aws-access-key-id

The AWS access key your were given when you signed up for AWS services.

You can create a new account by visiting "http://aws.amazon.com/".

aws-secret-access-key

The AWS secret access key you were given when you signed up for AWS services.

token

Pass the session token as the third argument on as SecurityToken in the options hash described below.

options

options is an optional hash reference containing the options listed below.

ServiceURL

default: https://queue.amazonaws.com

Set the ServiceUrl when you want to use a mocking service like LocalStack.
UserAgent

default: LWP::UserAgent
SignatureVersion

default: 2

Note: Signature Version 4 is supported by AWS::Signature4. If you use the Signature 4 signing facility, make sure your ServiceURL includes the region endpoint. Ex: https://sqs.us-east-1.amazonaws.com.
SecurityToken

For temporary credentials, add the security token returned from the AWS Security Token Service.
ServiceVersion

default: 2012-11-05
MaxErrorRetry

default: 3
credentials

An instance of a class (e.g. Amazon::Credentials) which supports the getters:
```
get_aws_access_key_id
get_aws_secret_access_key
get_token
```
You are encouraged to use this option rather than sending the credentials in the constructor.

createQueue

createQueue( request )

The CreateQueue action creates a new queue, or returns the URL of an existing one. When you request CreateQueue, you provide a name for the queue. To successfully create a new queue, you must provide a name that is unique within the scope of your own queues. If you provide the name of an existing queue, a new queue isn't created and an error isn't returned. Instead, the request succeeds and the queue URL for the existing queue is returned.

Exception: if you provide a value for DefaultVisibilityTimeout that is different from the value for the existing queue, you receive an error.

See "http://docs.amazonwebservices.com/AWSSimpleQueueService/2009-02-01/SQSDeveloperGuide/Query_QueryCreateQueue.html".

Returns an Amazon::SQS::Model::CreateQueueResponse object.

Throws an Amazon::SQS::Exception. Use eval to catch it.

See Amazon::SQS::Model::ChangeMessageVisibilityRequest for valid arguments.

deleteMessage
