RabbitMQ Client

This Python code provides a convenient interface for interacting with RabbitMQ, a message broker that enables communication between different components of a distributed system. The library includes classes for basic RabbitMQ operations, message publishing, and RPC (Remote Procedure Call) implementation.

Installation

Before using this code, ensure that you have the required dependencies installed. You can install them using the following command:

pip install aio-pika

Usage

1. Initializing RabbitMQ Connection

import asyncio
from your_module import RabbitClient

async def main():
    rabbit_url = "amqp://guest:guest@localhost:5672/"
    
    # Start the RabbitMQ connection
    await RabbitClient.start(url=rabbit_url)

if __name__ == "__main__":
    loop = asyncio.new_event_loop()
    loop.create_task(main())
    loop.run_forever()

2. Adding Callbacks for Message Handling

import asyncio
from your_module import RabbitClient, Callback

async def handle_message(message):
    print(f"Received message: {message}")

async def main():
    rabbit_url = "amqp://guest:guest@localhost:5672/"
    
    # Add a callback for handling messages from a specific queue
    callback = Callback(callback=handle_message, queue="your_queue_name")
    RabbitClient.add_callback(callback)

    # Start the RabbitMQ connection
    await RabbitClient.start(url=rabbit_url)
    
if __name__ == '__main__':
    loop = asyncio.new_event_loop()
    loop.create_task(main())
    loop.run_forever()

3. Publishing Messages

import asyncio
from your_module import RabbitClient

async def main():
    rabbit_url = "amqp://guest:guest@localhost:5672/"
    
    # Start the RabbitMQ connection
    await RabbitClient.start(url=rabbit_url)
    
    # Publish a message to a specific routing key and exchange
    await RabbitClient.publish(routing_key="your_routing_key", message="Hello, RabbitMQ!", exchange="your_exchange")

if __name__ == '__main__':
    loop = asyncio.new_event_loop()
    loop.create_task(main())
    loop.run_forever()

4. RPC (Remote Procedure Call) Implementation

import asyncio
from your_module import RabbitRPC

async def main():
    rabbit_url = "amqp://guest:guest@localhost:5672/"
    
    # Start the RabbitMQ connection
    await RabbitRPC.start(url=rabbit_url)
    
    # Execute an RPC call
    response = await RabbitRPC.execute(routing_key="your_routing_key", exchange="your_exchange", param1="value1", param2="value2")
    print(f"RPC Response: {response.decode()}")

if __name__ == '__main__':
    loop = asyncio.new_event_loop()
    loop.create_task(main())
    loop.run_forever()

Notes

Ensure that RabbitMQ server is running and reachable at the specified URL.
Customize the placeholders ("your_module", "your_queue_name", "your_routing_key", "your_exchange", etc.) with your specific values and names.

Feel free to modify and integrate this library into your project according to your requirements.
