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.
Before using this code, ensure that you have the required dependencies installed. You can install them using the following command:
pip install aio-pika
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()
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()
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()
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()
- 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.
