I know how to connect to broker by hbmqtt in script bash:

 hbmqtt_sub --url mqtt://guest:guest@localhost:15672 -t a/b

but in my code where i use hbmqtt library how can I set username and password

async def test_sub():
    client = MQTTClient()
    await client.connect(' mqtt://guest:guest@localhost:15672')
    await client.subscribe([
        ('a/b', QOS_1),
    ])

this code doesnt work!

What exactly doesn't work? – zr0gravity7 Dec 27 '21 at 07:47
it needs username and password in proper way, i use rabbitmq broker – amirhossein Dec 27 '21 at 07:58
are you try this? client.username_pw_set(username="name",password="pwd") – Sergey K Dec 27 '21 at 08:02
Maybe you mix up with port number? `5672` is default rabbitmq port. Also I see a extra whitespace in connection string at the start. – Yevhen Bondar Dec 27 '21 at 08:03
@СергейКрылов Does hbmqtt client have this attribute? – amirhossein Dec 27 '21 at 08:06
@Eugenij no it works in my browser on this port – amirhossein Dec 27 '21 at 08:07
@amirhossein Yes, you are right. Rabbitmq uses port `15672` for web UI and port `5672` for connection. Plz try `5672` in connection string – Yevhen Bondar Dec 27 '21 at 08:08
@Eugenij it gives me this error: hbmqtt.errors.HBMQTTException: Invalid fixed packet type 4 for ConnackPacket init – amirhossein Dec 27 '21 at 08:10

The error implies that the that RabitMQ is listening on that port is not MQTT as it is sending a response the client doesn't understand. – hardillb Dec 27 '21 at 09:37
@hardillb so how should I config it, should I make config file? – amirhossein Dec 27 '21 at 14:42
No idea, I don't use rabbitMQ. Do as I asked on your other question and include the details of how you have configured rabbitMQ so somebody that does can tell if it's correct – hardillb Dec 27 '21 at 15:57
