I’ve got a Phoenix application we’ve been running for some time. We now need to add AMQP as a message source. The AMQP messages will generally match the Phoenix routes in functionality. But we have substantial business logic in the Phoenix pipelines and controllers that we can’t easily refactor at this time.
In Phoenix app test code, we can use Phoenix.ConnTest to build up conn structs and dispatch calls to our Phoenix endpoints without actually going through TCP/HTTP.
Is it possible to use Phoenix.ConnTest at deployed runtime from our AMQP message subscriber, create a matching HTTP request in the form of a conn struct, and then use ConnTest.dispatch/4 or /5 to invoke our application endpoint so that the HTTP pipelines and business logic can be executed? Then extract the response from the returned conn struct and build a reply AMQP message?
