How to use TLS in Play!Framework WebSockets (“wss://”)

Question

I cannot use wss:// in my simple WebSocket app created with Play!Framework 2.2. It echoes the message back. The endpoint is like this

def indexW         


        

Answer 1

Did you try enabling https support on the Play server? It looks like you're trying to connect to the http port using wss, that can never work, you need to enable https, and then change the URL not just to wss, but also to use the https port.

To start a Play server with ssl turned on:

activator run -Dhttps.port=9443

Then connect to wss://localhost:9443/ws2.
