1.4. Terms and concepts

This section introduces the core API entities and describes how they operate together.

Table 1.1. API terms

EntityDescription

Container

A top-level container of connections.

Connection

A channel for communication between two peers on a network. It contains sessions.

Session

A context for sending and receiving messages. It contains senders and receivers.

Sender

A channel for sending messages to a target. It has a target.

Receiver

A channel for receiving messages from a source. It has a source.

Source

A named point of origin for messages.

Target

A named destination for messages.

Message

An application-specific piece of information.

Delivery

A message transfer.

AMQ Python sends and receives messages. Messages are transferred between connected peers over senders and receivers. Senders and receivers are established over sessions. Sessions are established over connections. Connections are established between two uniquely identified containers. Though a connection can have multiple sessions, often this is not needed. The API allows you to ignore sessions unless you require them.

A sending peer creates a sender to send messages. The sender has a target that identifies a queue or topic at the remote peer. A receiving peer creates a receiver to receive messages. The receiver has a source that identifies a queue or topic at the remote peer.

The sending of a message is called a delivery. The message is the content sent, including all metadata such as headers and annotations. The delivery is the protocol exchange associated with the transfer of that content.

To indicate that a delivery is complete, either the sender or the receiver settles it. When the other side learns that it has been settled, it will no longer communicate about that delivery. The receiver can also indicate whether it accepts or rejects the message.

1.5. Document conventions

In this document, sudo is used for any command that requires root privileges. You should always exercise caution when using sudo, as any changes can affect the entire system.

For more information about using sudo, see The sudo Command.

Chapter 2. Installation

This chapter guides you through the steps to install AMQ Python in your environment.

2.1. Prerequisites

To begin installation, use your subscription to access AMQ distribution files and repositories.

2.2. Installing on Red Hat Enterprise Linux

AMQ Python is distributed as a set of RPM packages for Red Hat Enterprise Linux. Follow these steps to install them.

  1. Use the subscription-manager command to subscribe to the required package repositories.

    Red Hat Enterprise Linux 6

    $ sudo subscription-manager repos --enable=amq-clients-2-for-rhel-6-server-rpms

    Red Hat Enterprise Linux 7

    $ sudo subscription-manager repos --enable=amq-clients-2-for-rhel-7-server-rpms

  2. Use the yum command to install the python-qpid-proton and python-qpid-proton-docs packages.

    $ sudo yum install python-qpid-proton python-qpid-proton-docs

Chapter 3. Getting started

This chapter guides you through a simple exercise to help you get started using AMQ Python.

3.1. Preparing the broker

The example programs require a running broker with a queue named examples. Follow these steps to define the queue and start the broker:

Procedure

  1. Install the broker.
  2. Create a broker instance. Enable anonymous access.
  3. Start the broker instance and check the console for any critical errors logged during startup.

    $ <broker-instance-dir>/bin/artemis run
    ...
    14:43:20,158 INFO  [org.apache.activemq.artemis.integration.bootstrap] AMQ101000: Starting ActiveMQ Artemis Server
    ...
    15:01:39,686 INFO  [org.apache.activemq.artemis.core.server] AMQ221020: Started Acceptor at 0.0.0.0:5672 for protocols [AMQP]
    ...
    15:01:39,691 INFO  [org.apache.activemq.artemis.core.server] AMQ221007: Server is now live
  4. Use the artemis queue command to create a queue called examples.

    <broker-instance-dir>/bin/artemis queue create --name examples --auto-create-address --anycast

    You are prompted to answer a series of questions. For yes or no questions, type N. Otherwise, press Enter to accept the default value.

3.2. Running Hello World

The Hello World example sends a message to the examples queue on the broker and then fetches it back. On success it prints Hello World! to the console.

Using a new terminal window, change directory to the AMQ Python examples directory and run the helloworld.py example.

$ cd /usr/share/proton-0.28.0/examples/python/
$ python helloworld.py
Hello World!

Chapter 4. Examples

This chapter demonstrates the use of AMQ Python through example programs.

See the Qpid Proton Python examples for more sample programs.

4.1. Sending messages

This client program connects to a server using <connection-url>, creates a sender for target <address>, sends a message containing <message-body>, closes the connection, and exits.

Example: Sending messages

from __future__ import print_function

import sys

from proton import Message
from proton.handlers import MessagingHandler
from proton.reactor import Container

class SendHandler(MessagingHandler):
    def __init__(self, conn_url, address, message_body):
        super(SendHandler, self).__init__()

        self.conn_url = conn_url
        self.address = address
        self.message_body = message_body

    def on_start(self, event):
        conn = event.container.connect(self.conn_url)
        event.container.create_sender(conn, self.address)

    def on_link_opened(self, event):
        print("SEND: Opened sender for target address '{0}'".format
              (event.sender.target.address))

    def on_sendable(self, event):
        message = Message(self.message_body)
        event.sender.send(message)

        print("SEND: Sent message '{0}'".format(message.body))

        event.sender.close()
        event.connection.close()

def main():
    try:
        conn_url, address, message_body = sys.argv[1:4]
    except ValueError:
        sys.exit("Usage: send.py <connection-url> <address> <message-body>")

    handler = SendHandler(conn_url, address, message_body)
    container = Container(handler)
    container.run()

if __name__ == "__main__":
    try:
        main()
    except KeyboardInterrupt:
        pass

Running the example

To run the example program, copy it to a local file and invoke it using the python command.

$ python send.py amqp://localhost queue1 hello

4.2. Receiving messages

This client program connects to a server using <connection-url>, creates a receiver for source <address>, and receives messages until it is terminated or it reaches <count> messages.

Example: Receiving messages

from __future__ import print_function

import sys

from proton.handlers import MessagingHandler
from proton.reactor import Container

class ReceiveHandler(MessagingHandler):
    def __init__(self, conn_url, address, desired):
        super(ReceiveHandler, self).__init__()

        self.conn_url = conn_url
        self.address = address
        self.desired = desired
        self.received = 0

    def on_start(self, event):
        conn = event.container.connect(self.conn_url)
        event.container.create_receiver(conn, self.address)

    def on_link_opened(self, event):
        print("RECEIVE: Created receiver for source address '{0}'".format
              (self.address))

    def on_message(self, event):
        message = event.message

        print("RECEIVE: Received message '{0}'".format(message.body))

        self.received += 1

        if self.received == self.desired:
            event.receiver.close()
            event.connection.close()

def main():
    try:
        conn_url, address = sys.argv[1:3]
    except ValueError:
        sys.exit("Usage: receive.py <connection-url> <address> [<message-count>]")

    try:
        desired = int(sys.argv[3])
    except (IndexError, ValueError):
        desired = 0

    handler = ReceiveHandler(conn_url, address, desired)
    container = Container(handler)
    container.run()

if __name__ == "__main__":
    try:
        main()
    except KeyboardInterrupt:
        pass

Running the example

To run the example program, copy it to a local file and invoke it using the python command.

$ python receive.py amqp://localhost queue1

Chapter 5. Using the API

This chapter explains how to use the AMQ Python API to perform common messaging tasks.

5.1. Basic operation

5.1.1. Handling messaging events

AMQ Python is an asynchronous event-driven API. To define how an application handles events, the user implements callback methods on the MessagingHandler class. These methods are then called as network activity or timers trigger new events.

Example: Handling messaging events

class ExampleHandler(MessagingHandler):
    def on_start(self, event):
        print("The container event loop has started")

    def on_sendable(self, event):
        print("A message can be sent")

    def on_message(self, event):
        print("A message is received")

These are only a few common-case events. The full set is documented in the API reference.

The event argument has attributes for accessing the object the event is regarding. Attributes with no relevance to a particular event are null.

Example: Accessing event objects

event.container
event.connection
event.session
event.sender
event.receiver
event.delivery
event.message

5.1.2. Creating a container

The container is the top-level API object. It is the entry point for creating connections, and it is responsible for running the main event loop. It is often constructed with a global event handler.

Example: Creating a container

handler = ExampleHandler()
container = Container(handler)
container.run()

Setting the container identity

Each container instance has a unique identity called the container ID. When AMQ Python makes a connection, it sends the container ID to the remote peer. To set the container ID, pass it to the Container constructor.

Example: Setting the container identity

container = Container(handler, "job-processor-3")

If the user does not set the ID, the library will generate a UUID when the container is constucted.

5.2. Network connections

5.2.1. Connection URLs

Connection URLs encode the information used to establish new connections.

Connection URL syntax

scheme://host[:port]

  • Scheme - The connection transport, either amqp for unencrypted TCP or amqps for TCP with SSL/TLS encryption.
  • Host - The remote network host. The value can be a hostname or a numeric IP address. IPv6 addresses must be enclosed in square brackets.
  • Port - The remote network port. This value is optional. The default value is 5672 for the amqp scheme and 5671 for the amqps scheme.

Connection URL examples

amqps://example.com
amqps://example.net:56720
amqp://127.0.0.1
amqp://[::1]:2000

5.2.2. Creating outgoing connections

To connect to a remote server, call the Container.connect() method with a connection URL. This is typically done inside the MessagingHandler.on_start() method.

Example: Creating outgoing connections

class ExampleHandler(MessagingHandler):
    def on_start(self, event):
        connection = event.container.connect("amqp://example.com")

    def on_connection_opened(self, event):
        print("Connection", **event.connection, "is open")

See the Section 5.4, “Security” section for information about creating secure connections.

5.2.3. Configuring reconnect

Reconnect allows a client to recover from lost connections. It is used to ensure that the components in a distributed system reestablish communication after temporary network or component failures.

AMQ Python enables reconnect by default. If a connection is lost or a connection attempt fails, the client will try again after a brief delay. The delay increases exponentially for each new attempt, up to a default maximum of 10 seconds.

To disable reconnect, set the reconnect connection option to False.

Example: Disabling reconnect

container.connect("amqp://example.com", reconnect=False)

To control the delays between connection attempts, define a class implementing the reset and next methods and set the reconnect connection option to an instance of that class.

Example: Configuring reconnect

class ExampleReconnect(object):
    def __init__(self):
        self.delay = 0

    def reset(self):
        self.delay = 0

    def next(self):
        if self.delay == 0:
            self.delay = 0.1
        else:
            self.delay = min(10, 2 * self.delay)

        return self.delay

container.connect("amqp://example.com", reconnect=ExampleReconnect())

The next method returns the next delay in seconds. The reset method is called once before the reconnect process begins.

5.2.4. Configuring failover

AMQ Python allows you to configure multiple connection endpoints. If connecting to one fails, the client attempts to connect to the next in the list. If the list is exhausted, the process starts over.

To specify multiple connection endpoints, set the urls connection option to a list of connection URLs.

Example: Configuring failover

urls = ["amqp://alpha.example.com", "amqp://beta.example.com"]
container.connect(urls=urls)

It is an error to use the url and urls options at the same time.

5.3. Message delivery

5.3.1. Sending messages

To send a message, override the on_sendable event handler and call the Sender.send() method. The sendable event fires when the Sender has enough credit to send at least one message.

Example: Sending messages

class ExampleHandler(MessagingHandler):
    def on_start(self, event):
        conn = event.container.connect("amqp://example.com")
        sender = event.container.create_sender(conn, "jobs")

    def on_sendable(self, event):
        message = Message(self.message_body)
        event.sender.send(message)

5.3.2. Tracking sent messages

When a message is sent, the sender can keep a reference to the delivery object representing the transfer. After the message is delivered, the receiver accepts or rejects it. The sender is notified of the outcome for each delivery.

To monitor the outcome of a sent message, override the on_accepted and on_rejected event handlers and map the delivery state update to the delivery returned from send().

Example: Tracking sent messages

def on_sendable(self, event):
    message = Message(self.message_body)
    delivery = event.sender.send(message)

def on_accepted(self, event):
    print("Delivery", event.delivery, "is accepted")

def on_rejected(self, event):
    print("Delivery", event.delivery, "is rejected")

5.3.3. Receiving messages

To receive a message, create a receiver and override the on_message event handler.

Example: Receiving messages

class ExampleHandler(MessagingHandler):
    def on_start(self, event):
        conn = event.container.connect("amqp://example.com")
        receiver = event.container.create_receiver(conn, "jobs")

    def on_message(self, event):
        print("Received message", event.message, "from", event.receiver)

5.3.4. Acknowledging received messages

To explicitly accept or reject a delivery, use the Delivery.update() method with the ACCEPTED or REJECTED state in the on_message event handler.

Example: Acknowledging received messages

def on_message(self, event):
    try:
        process_message(event.message)
        event.delivery.update(ACCEPTED)
    except:
        event.delivery.update(REJECTED)

By default, if you do not explicity acknowledge a delivery, then the library accepts it after on_message returns. To disable this behavior, set the auto_accept receiver option to false.

5.4. Security

5.4.1. Securing connections with SSL/TLS

AMQ Python uses SSL/TLS to encrypt communication between clients and servers.

To connect to a remote server with SSL/TLS, use a connection URL with the amqps scheme.

Example: Enabling SSL/TLS

container.connect("amqps://example.com")

5.4.2. Connecting with a user and password

AMQ Python can authenticate connections with a user and password.

To specify the credentials used for authentication, set the user and password options on the connect method.

Example: Connecting with a user and password

container.connect("amqps://example.com", user="alice", password="secret")

5.4.3. Configuring SASL authentication

AMQ Python uses the SASL protocol to perform authentication. SASL can use a number of different authentication mechanisms. When two network peers connect, they exchange their allowed mechanisms, and the strongest mechanism allowed by both is selected.

Note

The client uses Cyrus SASL to perform authentication. Cyrus SASL uses plug-ins to support specific SASL mechanisms. Before you can use a particular SASL mechanism, the relevant plug-in must be installed. For example, you need the cyrus-sasl-plain plug-in in order to use SASL PLAIN authentication.

To see a list of Cyrus SASL plug-ins in Red Hat Enterprise Linux, use the yum search cyrus-sasl command. To install a Cyrus SASL plug-in, use the yum install PLUG-IN command.

By default, AMQ Python allows all of the mechanisms supported by the local SASL library configuration. To restrict the allowed mechanisms and thereby control what mechanisms can be negotiated, use the allowed_mechs connection option. It takes a string containing a space-separated list of mechanism names.

Example: Configuring SASL authentication

container.connect("amqps://example.com", allowed_mechs="ANONYMOUS")

This example forces the connection to authenticate using the ANONYMOUS mechanism even if the server we connect to offers other options. Valid mechanisms include ANONYMOUS, PLAIN, SCRAM-SHA-256, SCRAM-SHA-1, GSSAPI, and EXTERNAL.

AMQ Python enables SASL by default. To disable it, set the sasl_enabled connection option to false.

Example: Disabling SASL

event.container.connect("amqps://example.com", sasl_enabled=False)

5.4.4. Authenticating using Kerberos

Kerberos is a network protocol for centrally managed authentication based on the exchange of encrypted tickets. See Using Kerberos for more information.

  1. Configure Kerberos in your operating system. See Configuring Kerberos to set up Kerberos on Red Hat Enterprise Linux.
  2. Enable the GSSAPI SASL mechanism in your client application.

    container.connect("amqps://example.com", allowed_mechs="GSSAPI")
  3. Use the kinit command to authenticate your user credentials and store the resulting Kerberos ticket.

    $ kinit USER@REALM
  4. Run the client program.

5.5. More information

For more information, see the API reference.

Chapter 6. File-based configuration

AMQ Python can read the configuration options used to establish connections from a local file named connect.json. This enables you to configure connections in your application at the time of deployment.

The library attempts to read the file when the application calls the container connect method without supplying any connection options.

Note

This feature is currently unavailable on Microsoft Windows.

6.1. File locations

If set, AMQ Python uses the value of the MESSAGING_CONNECT_FILE environment variable to locate the configuration file.

If MESSAGING_CONNECT_FILE is not set, AMQ Python searches for a file named connect.json at the following locations and in the order shown. It stops at the first match it encounters.

  1. $PWD/connect.json, where $PWD is the current working directory of the client process
  2. $HOME/.config/messaging/connect.json, where $HOME is the current user home directory
  3. /etc/messaging/connect.json

6.2. File format

The connect.json file contains JSON data, with additional support for JavaScript comments.

Many of the options have default values, so a simple example need only provide a few details:

Example: A simple connect.json file

{
    "host": "example.com",
    "user": "alice",
    "password": "secret"
}

SASL and SSL/TLS options are nested under "sasl" and "tls" namespaces:

Example: A connect.json file with SASL and SSL/TLS options

{
    "host": "example.com",
    "user": "ortega",
    "password": "secret",
    "sasl": {
        "mechanisms": ["SCRAM-SHA-1", "SCRAM-SHA-256"]
    },
    "tls": {
        "cert": "/home/ortega/cert.pem",
        "key": "/home/ortega/key.pem"
    }
}

6.3. Configuration options

The option keys containing a dot (.) represent attributes nested inside a namespace.

Chapter 7. Interoperability

This chapter discusses how to use AMQ Python in combination with other AMQ components. For an overview of the compatibility of AMQ components, see the product introduction.

7.1. Interoperating with other AMQP clients

AMQP messages are composed using the AMQP type system. This common format is one of the reasons AMQP clients in different languages are able to interoperate with each other.

When sending messages, AMQ Python automatically converts language-native types to AMQP-encoded data. When receiving messages, the reverse conversion takes place.

7.2. Interoperating with AMQ JMS

AMQP defines a standard mapping to the JMS messaging model. This section discusses the various aspects of that mapping. For more information, see the AMQ JMS Interoperability chapter.

JMS message types

AMQ Python provides a single message type whose body type can vary. By contrast, the JMS API uses different message types to represent different kinds of data. The table below indicates how particular body types map to JMS message types.

For more explicit control of the resulting JMS message type, you can set the x-opt-jms-msg-type message annotation. See the AMQ JMS Interoperability chapter for more information.
