[rabbitmq-discuss] How to specify user/pass

Mon Jul 2 23:22:10 BST 2012

Yeah, that works fine with internal authentication scheme of rabbitmq.

But what about https://github.com/simonmacmullen/rabbitmq-auth-backend-http
. I've installed the plugin successfully. 

Then I've put the following into ebin/rabbit.app as HTTP README says:

    [{description,"RabbitMQ"},

               {linger,{true,0}},
               {exit_on_close,false}]}]}]}.

Notice the:
 {rabbit, [{auth_backends, [rabbit_auth_backend_http]}]},
  {rabbitmq_auth_backend_http,
   [{user_path,     "http://some-server/auth/user"},
    {vhost_path,    "http://some-server/auth/vhost"},
    {resource_path, "http://some-server/auth/resource"}]}

The problem is that with the following send.py I cannot login to the
rabbitmq with HTTP server:
#!/usr/bin/env python
import pika

credentials = pika.PlainCredentials('test', 'test')
params = pika.ConnectionParameters(credentials=credentials,
host="localhost", virtual_host='/')
connection = pika.BlockingConnection(params)
channel = connection.channel()
channel.queue_declare(queue='')
channel.basic_publish(exchange='logs', routing_key='', body='Hello World!')
connection.close()

I specified the test:test username and password, since that's what I added
to the django application, which is included as an example to the HTTP
plugin. If I enter the GET request:
    http://127.0.0.1:8000/auth/user?username=test&password=test

everything is ok - the user is authenticated.

But when I try to login with the send.py script, the GET request isn't even
made. Now my question is: how to fix rabbitmq for rabbitmq to start making
GET requests to the http server or how to debug an issue?

Thank you
