Erlang Heroku RabbitMQ - heroku

Question

i run in terminal command
heroku config:get RABBITMQ_BIGWIG_RX_URL --app app1
give me a string
amqp://Ajwj23X3:nsi3sC#leaping-charlock-1.bigwig.lshift.net:18372/Hbau2x3d
I copy login,password,url,port to erlang code
-record(amqp_params_network, {username = <<"Ajwj23X3">>,
password = <<"nsi3sC">>,
virtual_host = <<"/">>,
host = "leaping-charlock-1.bigwig.lshift.net",
port = 18372,
channel_max = 0,
frame_max = 0,
heartbeat = 0,
connection_timeout = infinity,
ssl_options = none,
auth_mechanisms =
[fun amqp_auth_mechanisms:plain/3,
fun amqp_auth_mechanisms:amqplain/3],
client_properties = [],
socket_options = []}).
But when i run program and connection false
How correctly write amqp_params_network in erlang for heroku rabbitqm?

Answer 1

-record is the definition of the record type, and the values contained there are just defaults. It would be rather unusual to hard-code connection parameters as defaults for the record, even more so when the record definition is provided by an external library.
Instead, construct a record instance with the required data:
Params = #amqp_params_network{username = <<"Ajwj23X3">>,
password = <<"nsi3sC">>,
host = "leaping-charlock-1.bigwig.lshift.net",
port = 18372},
and use that instance when connecting:
{ok, Connection} = amqp_connection:start(Params),
