I just set up a RabbitMQ add-on in heroku. After developing my app to queue up and consume messages running on a local instance, I deployed it to Heroku and have not been able to connect successfully yet. The username/password & hostname/port/vhost are all from heroku config. If I change the username or password, the error changes to ProbableAuthenticationError which makes me believe the authentication is at least correct, but likely an issue with my vhost or some other missing configuration. I haven't seen any similar questions on SO or after an hour of Googling that didn't address my issue.
I have tried both the RABBITMQ_BIGWIG_RX_URL and RABBITMQ_BIGWIG_TX_URL environment variables for both sending and consuming, and no combination seems to work. Below is the code I have for attempting to connect.
url = 'small-laurel-24.bigwig.lshift.net'
port = 10019
vhost = '/notmyrealvhost'
credentials = pika.PlainCredentials('username', 'password')
parameters = pika.ConnectionParameters(url, port, vhost, credentials=credentials)
connection = pika.BlockingConnection(parameters)
Is there something I'm missing or any way to figure out what specifically is configured wrong? I'm at a loss here. Much thanks in advance!
I am running pika 0.9.14, python 2.7.3.
I ended up solving my problem by using the URLParameters class on pika to parse the URL from Heroku's environment variable.
This takes the string like
amqp://username:password@small-laurel-24.bigwig.lshift.net:10018/notmyrealvhost and parses everything as needed. I was unnecessarily complicating things by doing it myself.
