> RabbitMQ Consumer does not pick up REPLY_TO
> -------------------------------------------
>
> Key: CAMEL-7009
> URL: https://issues.apache.org/jira/browse/CAMEL-7009
> Project: Camel
> Issue Type: Bug
> Components: camel-rabbitmq
> Affects Versions: 2.12.1
> Reporter: Jason Foster
> Assignee: Willem Jiang
> Fix For: 2.12.2
>
>
> When using RPC in RabbitMQ, the producer sets up an exclusive queue and
> specifies that queue as the reply_to on outgoing messages. When the consumer
> in camel-rabbitmq receives the messages, the reply_to isn't available on the
> exchange, so no RPC calls can be completed.
> The following Python script (from RabbitMQ In Action) produces the message
> with a reply_to property:
> import time, json, pika
> creds_broker = pika.PlainCredentials("guest", "guest")
> conn_params = pika.ConnectionParameters("localhost",
> virtual_host = "/",
> credentials = creds_broker)
> conn_broker = pika.BlockingConnection(conn_params)
> channel = conn_broker.channel()
> msg = json.dumps({"client_name": "RPC Client 1.0",
> "time" : time.time()})
> result = channel.queue_declare(exclusive=True, auto_delete=True)
> msg_props = pika.BasicProperties()
> msg_props.reply_to = result.method.queue
> channel.basic_publish(body=msg,
> exchange="talentsprout.rpc",
> properties=msg_props,
> routing_key="ping")
> print "Sent 'Ping' RPC call. Waiting for reply..."
> def reply_callback(channel, method, header, body):
> """Receives RPC server replies."""
> print "RPC Reply --- " + body
> channel.stop_consuming()
> channel.basic_consume(reply_callback,
> queue=result.method.queue,
> consumer_tag=result.method.queue)
> channel.start_consuming()
> The following route in Camel would consume messages from this queue:
>
> from("rabbitmq://192.168.213.130/talentsprout.rpc?queue=ping&routingKey=ping&durable=False&autoDelete=False&autoAck=False&username=guest&password=guest")
> .log("Headers: ${headers}");
> The log statement from that route shows that no reply_to header is added.
> Without this feature, RPC from external producers cannot work.
