Python language binding for IronMQ. IronMQ is an elastic message queue for managing data and event flow within cloud applications and between systems. See How It Works

Getting Started

Get credentials

To start using iron_mq_python, you need to sign up and get an OAuth2 token.

Go to http://iron.io/ and sign up.
Get an OAuth2 Token at http://hud.iron.io/tokens

Install iron_mq_python

pip install iron-mq

or just copy iron_mq.py and include it in your script:

from iron_mq import *

Configure

ironmq = IronMQ()

will try reasonable defaults, accepting following optionally:

ironmq = IronMQ(host="mq-aws-us-east-1.iron.io",
                project_id="500f7b....b0f302e9",
                token="Et1En7.....0LuW39Q",
                protocol="https", port=443,
                api_version=1,
                config_file=None)

The Basics

Listing queues

ironmq.queues()

returns list of queues names

we get queue by name:

queue = ironmq.queue("test_queue")

Push a message(s) on the queue:

queue.post("Hello world")

Message can be described by dict:

message = {
    "body" : "Test Message",
    "timeout" : 120, # Timeout, in seconds. After timeout, item will be placed back on queue. Defaults to 60.
    "delay" : 5, # The item will not be available on the queue until this many seconds have passed. Defaults to 0.
    "expires_in" : 2*24*3600 # How long, in seconds, to keep the item on the queue before it is deleted.
}
queue.post(message)

We can post several messages at once:

queue.post("more", "and more", "and more")
queue.post(*[str(i) for i in range(10)])

Pop a message off the queue:

queue.get(max=10, timeout=None) # {"messages": [{'id': '..', 'body': '..'}, ..]}

Set max to the number of messages to return, 1 by default. An optional timeout parameter can be used to specify a per-message timeout, or the timeout the message was posted with will be used.

When you pop/get a message from the queue, it will NOT be deleted. It will eventually go back onto the queue after a timeout if you don't delete it (default timeout is 60 seconds).

Get message by id

queue.get_message_by_id("xxxxxxxx")

Delete a message from the queue:

queue.delete(message_id)

Delete a message from the queue when you're done with it.

Delete multiple messages in one API call:

queue.delete_multiple("xxxxxxxxx", "xxxxxxxxx");

Delete multiple messages specified by messages id array.

Clear a queue:

queue.clear()

Get queue size, id, total_messages and whole info

queue.info()
 # {u'id': u'502d03d3211a8f5e7742d224',
 # u'name': u'queue12',
 # u'reserved': 0,
 # u'size': 15,
 # u'total_messages': 17}
queue.size() # 15
queue.name
queue.total_messages() # 17
queue.id() # u'502d03d3211a8f5e7742d224'

Peek at messages

To view messages without reserving them, use peek:

msgs = queue.peek(max=10) # {"messages": [{'id': '..', 'body': '..'}, ..]}

Touch a message

To extend the reservation on a reserved message, use touch. The message reservation will be extended by the message's timeout.

queue.touch(msg_id)

Release a reserved message

To release a message that is currently reserved, use release:

queue.release(msg_id, delay=30) # message will be released after delay seconds, 0 by defaults

Delete a queue

To delete a queue, use delete_queue:

queue.delete_queue()

Push Queues

Update Queue Information

To update the queue's push type and subscribers, use update:

queue.update(subscribers=["http://endpoint1.com", "https://end.point.com/2"], push_type"unicast")

Add subscribers to a push queue

queue.add_subscribers(*["http://endpoint1.com", "https://end.point.com/2"])

Remove subscribers from a push queue

queue.remove_subscribers(*["http://endpoint1.com", "https://end.point.com/2"])

Get the push statuses of a message

queue.get_message_push_statuses(message_id) # {"subscribers": [{"retries_delay": 60, "retries_remaining": 2, "status_code": 200, "status": "deleted", "url": "http://endpoint1.com", "id": "52.."}, {..}, ..]}

Delete a pushed message

If you respond with a 202 status code, the pushed message will be reserved, not deleted, and should be manually deleted. You can get the message ID and subscriber ID from the push message's headers.

queue.delete_message_push_status(message_id, subscriber_id)

Pull queues

Add alerts to a queue

fixed_desc_alert = {'type': 'fixed', 'direction': 'desc', 'trigger': 1000, 'queue': 'q'}
progressive_asc_alert = {'type': 'progressive', 'direction': 'asc', 'trigger': 10000, 'queue': 'q'}
queue.add_alerts(*[fixed_desc_alert, progressive_asc_alert])

Update alerts in a queue

progressive_asc_alert = {'type': 'progressive', 'direction': 'asc', 'trigger': 5000, 'queue': 'q'}
queue.update_alerts(*[progressive_asc_alert])

Remove alerts from a queue

q.remove_alerts(*['5305d3b5a3e920763013c796', '513015d32b5a3e763013c796'])

Remove single alert from a queue

q.remove_alert('5305d3b5a3e920763013c796')
