How to read websocket response in linux shell

Question

curl \"wss://ws-feed.gd         


        

Answer 1

You can connect to your server using Telnet also

     telnet 120.22.37.128 6870

Once you connect you can send request in Json format

     {"requestType":"hi"}     

Here 6870 is port port and to open port you need to run

     sudo ufw allow 6870 

And to check pm2 logs you required to use below command

    pm2 logs 0

Hope this hepls.
