conn, err := amqp.Dial("amqp://guest:guest@localhost:5672/") if err != nil { log.Fatalf("Failed to connect to RabbitMQ: %v", err) } defer conn.Close()In this example, we use the amqp.Dial method to establish a connection to an AMQP server running on the local machine, using the default login credentials of 'guest' and 'guest'. If there's an error during the connection process, we use log.Fatalf to print an error and terminate the program. Finally, we defer a call to conn.Close() to ensure that the connection is closed when the program exits. The Connection class provides many other useful methods as well, including a method for opening channels, a method for retrieving server properties, and a method for checking the connection status. Overall, the github.com/streadway/amqp package library is a powerful and flexible tool for building AMQP-based messaging systems in Go.
