Crossbar Node with JSONRPC Message Handling

This code defines a function named `random_crossbar_function` that generates a component and registers it to a Crossbar node. The component receives messages via JSONRPC protocol and prints them.

Technology Stack : Crossbar

Code Type : Function

Code Difficulty : Intermediate
