I wrote receiver as below:
import pika
connection = pika.BlockingConnection(pika.ConnectionParameters(host='localhost'))
ch = connection.channel()
ch.exchange_declare(exchange='ex1', exchange_type='fanout')
ch.queue_declare(queue='q1',exclusive=True)
ch.queue_bind(exchange='ex1',queue='q1')
print("wating for log")
def callback(ch, method, properties, body):
print(f'This is from reciver {body}')
ch.basic_consume(queue='q1',on_message_callback=callback, auto_ack=True)
ch.start_consuming()
and i got this error when run it:
Traceback (most recent call last):
