MCP Python worker extension for Azure Functions.

Azure Functions Extensions Bindings ServiceBus library for Python

This library allows ServiceBus Triggers in Python Function Apps to recognize and bind to client types from the Azure ServiceBus sdk.

The SDK types can be generated from:

• ServiceBus Triggers

The supported ServiceBus SDK types include:

• ServiceBusReceivedMessage

Source code | Package (PyPi) | Samples

Getting started

Prerequisites

• Python 3.9 or later is required to use this package. For more details, please read our page on Python Functions version support policy.

• You must have an Azure subscription and a ServiceBus Resource to use this package.

Install the package

Install the Azure Functions Extensions Bindings ServiceBus library for Python with pip:

pip install azurefunctions-extensions-bindings-servicebus

Bind to the SDK-type

The Azure Functions Extensions Bindings ServiceBus library for Python allows you to create a function app with a ServiceBus Trigger and define the type as a ServiceBusReceivedMessage. Instead of receiving a ServiceBusMessage, when the function is executed, the type returned will be the defined SDK-type and have all the properties and methods available as seen in the Azure ServiceBus library for Python.

import logging
import azure.functions as func
import azurefunctions.extensions.bindings.servicebus as servicebus

app = func.FunctionApp(http_auth_level=func.AuthLevel.FUNCTION)

@app.service_bus_queue_trigger(arg_name="receivedmessage",
                               queue_name="QUEUE_NAME",
                               connection="SERVICEBUS_CONNECTION")
def servicebus_queue_trigger(receivedmessage: servicebus.ServiceBusReceivedMessage):
    logging.info("Python ServiceBus queue trigger processed message.")
    logging.info("Receiving: %s\n"
                 "Body: %s\n"
                 "Enqueued time: %s\n"
                 "Lock Token: %s\n"
                 "Locked until : %s\n"
                 "Message ID: %s\n"
                 "Sequence number: %s\n",
                 receivedmessage,
                 receivedmessage.body,
                 receivedmessage.enqueued_time_utc,
                 receivedmessage.lock_token,
                 receivedmessage.locked_until,
                 receivedmessage.message_id,
                 receivedmessage.sequence_number)

Troubleshooting

General

The SDK-types raise exceptions defined in Azure Core.

This list can be used for reference to catch thrown exceptions. To get the specific error code of the exception, use the error_code attribute, i.e, exception.error_code.

Next steps

More sample code

Get started with our ServiceBus samples.

Several samples are available in this GitHub repository. These samples provide example code for additional scenarios commonly encountered while working with Azure ServiceBus:

• servicebus_samples_single - Examples for using the ServiceBusReceivedMessage type:

  • From ServiceBus Queue Trigger (Single Message)
  • From ServiceBus Topic Trigger (Single Message)

• servicebus_samples_batch - Examples for interacting with batches:

  • From ServiceBus Queue Trigger (Batch)
  • From ServiceBus Topic Trigger (Batch)
