[question] How to run the server normally when running in REQ mode? about nng HOT 3 CLOSED

This protocol does not let you send directed messages to a specific client.

Thank you.
I'm trying a way, register through nng_pipe_notify, apply a new context in the callback function, associate the pipe with the context, keep the context to communicate with the specific client in the future.
But the problem is, how to associate the pipe with the newly created context?

Generally what you want to do isn't possible for ordinary applications. This kind of thing is the purview of protocol implementations -- you could see for example how REQ/REP do it, or how PAIRv1 does it.

The goal of Scalability Protocols is to solve these common kinds of problems for you, so that you don't have to do it yourself. Unfortunately, not everyone's scenario always fits, but a significant percentage of them do.
