topic subscription always bind to amq.topic exchange

[ericln]

I am trying to use bus.subscribe('', func...), I am wondering how i can assign the exchange name ? i tried it on the bus creation in the options params, but nothing seems to work

any idea?

This is probably a bug, in that it is defaulting to 'amq.topic' whenever subscribe options don't have the exchangeName provided. A better solution would probably be for me to assign this.exchangeName = options.exchangeName || options.bus.exchangeName; in pubsubqueue.js.

If you don't mind the syntax (temporarily, at least) you should be able to do something like the following to set the exchange in the internal pubsubqueue:

bus.publish('routing.key', { my: 'message' }, { exchangeName: 'new.topic.exchange' });

I'll take a look at updating

servicebus/bus/rabbitmq/pubsubqueue.js

Line 30 in 281a375

this.exchangeName = options.exchangeName || 'amq.topic';

to default to the bus exchangeName, when an override option is not provided.

Let me know how that works for you.
